Answer:
A, B, and D
Step-by-step explanation:
Only the functions that have x by itself between the absolute value signs (A, B, and D) are symmetric with respect to the y-axis .
Placing a constant outside the absolute value signs moves the function up or down the y-axis but retains the symmetry.
Adding a constant inside the absolute value signs (as in C and E) moves the axis of symmetry to the left or right of the y-axis.
In the diagram, both A and B are symmetric with respect to the y-axis, but C has been shifted three units to the left.
Ms. Kendrick plans to buy a laptop for $1,345 in 12 weeks. She has already saved $145. How much should she save each week so she can buy the laptop?
Subtract how much she has saved from the total
1345 - 145 = 1200
She needs to save $1,200 in 12 weeks, now divide thow much she needs to save by the number of weeks to find how much she needs to save each week:
1200 / 12 = 100
She needs to save $100 per week.

12 An expression is shown. 83.31 x 6.2 What is the value of the expression?
A. 505.422
B. 506.522
C. 513.422
D. 515.522
please explain thank you.
Answer:
Step-by-step explanation:
In this type of problem it's reasonable to use a calculator for the computation. Here, 83.31·6.2 = 516.522. Double check to ensure that you've copied all of the possible answer choices correctly.
The value of the expression is 516.522, which corresponds to option B.
To solve the expression 83.31 * 6.2, we need to multiply the two numbers. Here is the step-by-step calculation:
Multiply 83.31 by 6.2 without considering the decimal places: 8331 * 62 = 516,522.
Count the total number of decimal places in the factors. In this case, 83.31 has two decimal places, and 6.2 has one, so there are three decimal places in total.
Place the decimal point in the result (516,522) to reflect the combined number of decimal places from the factors: 516.522.
Therefore, the value of the expression 83.31 x 6.2 is 516.522, which corresponds to option B.
x/-9 ≥ 3
Solve for x
Your answer must be simplified
(x/-9 is supposed to be a fraction)
Answer:
x ≤ -27
Step-by-step explanation:
x/-9 ≥ 3
well since theres division and we want to separate the x's and the naked numbers by themselves were going to have to multiply
x ≥ 3 x -9
x ≥ - 27 (but since theres a negative the symbol ≥ is going to switch)
x ≤ -27
TIP: remember we always do the opposite when switching a numbers place for example if we have +9 if we switch it place to the other side its going to become -9, same thing with multiplication and division.
example:
3 + x = 5 or 3x = 5
x = 5 - 3 x = 5/3
~batmans wife dun dun dun...aka ~serenitybella
The solution to the inequality (x/-9) ≥ 3 in fraction form is x ≤ -27.
The relationship between the two values which are either greater or lesser than each other but not equal is called inequality.
The primary application of inequality is to compare two numbers on a number line.
The inequality can be solved as:
(x/-9) ≥ 3
Multiply both sides of the inequality by -9. The multiplication of a number with a negative sign changes the direction of the inequality.
The equation can be written as:
[tex]\dfrac{-9x}{-9} \leq -9(3)[/tex]
x ≤ -27
Thus, the solution to the inequality (x/-9) ≥ 3 is x ≤ -27.

two cars are traveling in the same direction. The first car is going 40 mi/h, and the second car is going 55 mi/h. the first car left 3 hours before the second car. which equation could you solve to find how many hours it will take for the second car to catch up to the first car?
Answer:
8 hours
Step-by-step explanation:
first car: speed=40, time=(t+3), distance=s1
second car: speed=55, time=t, distance=s2
speed=distance/time
distance=speed×time
s1=40×(t+3)
s2=55×t
since the cars would travel the same distance; s1=s2
40(t+3) = 55t
40t+120 = 55t
15t = 120
t=8
Find the average rate of change for f (x)=x2+7x+10 from x=0 to x=2
Answer:
9
Step-by-step explanation:
[tex] average~rate~of~change = \dfrac{f(x_2) - f(x_1)}{x_2 - x_1} [/tex]
[tex] x_1 = 0 [/tex]
[tex] x_2 = 2 [/tex]

[tex] average~rate~of~change = \dfrac{18}{2} [/tex]
[tex] average~rate~of~change = 9 [/tex]
Answer:

A shipment to a warehouse consist of 4500 MP3 players. The manager chooses a random sample of 50 MP3 players and finds 2 are defective. How many MP3 players in the shipment are likely to be defective?
There are likely approximately 180 defective MP3 players in a shipment of 4,500 units.
The question asks how many MP3 players in a shipment of 4,500 units are likely to be defective given that a random sample of 50 MP3 players found 2 defective ones. To estimate the number of defective players in the entire shipment, we can use proportion. If 2 out of 50 MP3 players are defective, we set up a proportion to estimate the likely number of defectives in the entire 4,500 units.
Assuming the sample is representative of the whole shipment, the proportion would be:
2 (defective in sample) / 50 (sample size) = x (estimated defectives in shipment) / 4,500 (shipment size)
To solve for x, the likely number of defective MP3 players, we cross-multiply and divide:
2 / 50 = x / 4,500
50x = 2 * 4,500
50x = 9,000
x = 9,000 / 50
x = 180
Therefore, using the sample proportion, we would expect there to be approximately 180 defective MP3 players in the shipment.

Answer:
Mark the triangle the same on the bottom, that leaves the rectangle, both ends of the rectangle is 2.5 in. for the rest, just use a ruler.
Step-by-step explanation:
On the Richter scale, the magnitude, M, of an earthquake is given by M= 2/3logE/Eo, where E is the energy released by the earthquake measured in joules, and Eo is the energy released by a very small reference earthquake. Eo has been standardized to 10^4.4 joules.
Part A
The earthquake in Haiti in 2010 released 2.0*10^15 joules. What was its magnitude on the Richter scale?
Part B
If the energy release of one earthquake is 10,000 times that of another, how much larger is the Richter scale reading of the larger earthquake than the smaller?
Answer:
See below
Step-by-step explanation:
Part A
Formula
M = 2/3 * log(E/Eo)
Givens
M = ??
E = 2 * 10^15 joules
Eo = 10^4.4
Solution
M = (2/3) * log(2 * 10^15 / 10^4.4)
M = (2/3 ) log (7.96 * 10 ^ 11)
M = (2/3) * 11.901
M = 7.934
Part B
What the question is saying is that E/Eo = 10000
You don't have to figure out exact values.
M = 2/3 * log(10000)
M = 2/3 * 4
M = 8/3 or 2 2/3 or 2.66667
If you have choices, please list them.
Answer:
A ; M = 7.267
B ; M = 2.667
Step-by-step explanation:
Formula
M = (2/3) log (E/Eo)
M = 2/3 * log (2 * 10^15/10^(4.4) )
M = 2/3 * log( 7.9621* 10^10)
M = 2/3 * 10.901
M = 7.267 on the Richter scale.
Part B
Suppose that you use Eo and your base. Eo is 10^4.4
Now the new earthquake is E = 10000 * Eo
So what you get now is M = (2/3)* Log(10000 * Eo / Eo )
M = 2/3 * log(10000)
M = 2/3 of 4
M = 8/3
M = 2.6667
What this tells you is that if the original reading was (say) 6 then the 10000 times bigger reading would 8.266667

Carla spent two-fifths of her savings on a bracelet and had 9 left over. How many dollars did Carla's bracelet cost?
Final answer:
Carla spent two-fifths of her savings on a bracelet and had $9 left. Her original savings were $22.50, so the bracelet cost $9.
Explanation:
Carla spent two-fifths of her savings on a bracelet and had $9 left over. To determine the cost of Carla's bracelet, we need to let s represent her original savings. According to the problem, the remaining savings after purchasing the bracelet is s - (2/5)s = $9.
To solve for the cost of the bracelet, we can set up the equation (2/5)s = s - $9. By multiplying both sides by 5/2 to isolate s, we get:
s = (5/2) * ($9)
s = $22.50
So her original savings were $22.50. This means Carla spent (2/5) * $22.50 on the bracelet. Calculating this gives:
Cost of bracelet = (2/5) * $22.50
Cost of bracelet = $9
Thus, Carla's bracelet cost $9.
a certain rectangle has an area of x^2+7x+12. Factor the trinomial to find the length and width of the rectangle. (Please show the steps for working this out)
Answer:
(x + 3)(x + 4)
Step-by-step explanation:
To factor the trinomial
Consider the factors of the constant term ( + 12) which sum to give the coefficient of the x- term ( + 7)
The factors are + 3 and + 4, since
3 × 4 = 12 and 3 + 4 = 7, hence
x² + 7x + 12 = (x + 3)(x + 4)
Thus length can be x + 3 or x + 4 and
the width can be x + 4 or x + 3

what is the value of 6x=5y- 35
Answer:
ok
Step-by-step explanation:
The value of x, given the equation, can be found to be (5y - 35) / 6.
How to solve for x ?To find the value of x in the equation 6x = 5y - 35, you need to isolate x.
Start with the equation:
6 x = 5 y - 35
To isolate x, divide both sides of the equation by 6:
( 6 x ) / 6 = ( 5 y - 35 ) / 6
Simplify both sides:
x = ( 5 y - 35 ) / 6
So, the value of x is ( 5 y - 35 ) / 6.

A quadrilateral has vertices with coordinates (-3,1),(0,3),(5,2) and (-1,-2). Which type of quadrilateral is this?
AB and DC are parallel to each other and both are perpendicular to AD. So the quadrilateral is a right angled trapezoid. Hope this helps! :)
Final answer:
The given quadrilateral cannot be classified into a specific type.
Explanation:
The given quadrilateral has vertices with coordinates (-3,1), (0,3), (5,2), and (-1,-2). To determine the type of quadrilateral, we can find the slopes of the opposite sides. If the slopes are equal, the quadrilateral is a parallelogram. If the slopes are perpendicular, the quadrilateral is a rectangle. If both conditions are satisfied (equal slopes and perpendicular slopes), then the quadrilateral is a square.
Using the formula for slope between two points, we find:
Slope of the first side: (-3,1) to (0,3) -> m1 = (3 - 1) / (0 - (-3)) = 2/3
Slope of the second side: (-1,-2) to (-3,1) -> m2 = (1 - (-2)) / (-3 - (-1)) = 3/2
Slope of the third side: (-3,1) to (5,2) -> m3 = (2 - 1) / (5 - (-3)) = 1/8
Slope of the fourth side: (0,3) to (5,2) -> m4 = (2 - 3) / (5 - 0) = -1/5
Since the slopes of opposite sides are neither equal nor perpendicular, the given quadrilateral is neither a parallelogram, rectangle, nor a square. Therefore, the type of quadrilateral cannot be determined.
a cone has a volume of 6 cubic inches. what is the volume of a cylinder that the cone fits exactly inside of
Answer:
= 18 cubic inches
Step-by-step explanation:
The volume of a cone is given by the formula;
V = 1/3 × base area × height
While that of cylinder is given by the formula;
Volume = Base area × height
Since we need the cylinder to fit exactly inside the cone, then it means that their bases are the same and heights are the same.
Therefore;
The cone has three times less volume compared to the cylinder.
Thus;
Volume of the cylinder = Volume of cone × 3
= 6 In³ × 3
= 18 cubic inches

Which number is greater than (>) 6.841?
Answer:6.95
6.95= 6.95>6.841
6.8= 6.800<6.841
6.786<6.841
6.839<6.841
Answer:
6.95
Step-by-step explanation:
We can find the answer by analyzing the options and deducing which is greater or less.
That is, if we have the number 6.841, the number 6.95 must be greater because it has 9 intead of an 8, which makes it a bigger number.
We can also make a division between the original number and the number that we want to know if it is greater or less, and if the division is less than 1 it means that the number is greater, and if the division is greater than 1 it means that the number is smaller.
6.841/6.8 = 1.006 ⇒⇒ 6.8 is smaller than 6.841
6.841/6.786 = 1.008 ⇒⇒ 6.786 is smaller than 6.841
6.841/6.839 = 1.0003 ⇒⇒ 6.839 is smaller than 6.841
6.841/6.95= 0.98 ⇒⇒ 6.95 is greater than 6.841
one third the difference of two number is 12. if the larger number is 9, what is the sum of the two numbers
x=smaller number
y=larger number
x+y=12
y=3x-6
Let's begin with the first equation...
x+y=12
Let's substitute...
x+(3x-6)=12
4x-6=12
Let's add 6 to both sides as we proceed to isolate x...
6+4x-6=12+6
4x=18
Let's divide both sides by 4...
(4x)/4=18/4
x=9/2=4.5---smaller number
12-4.5=7.5s larger number
Answer:
The sum of the two numbers is -18.
Step-by-step explanation:
You can work your way through the problem starting with ...
1/3 the difference of two numbers is 12
Since 3 times 12 is 36, the difference of the two numbers is 36.
Then you are told ...
the larger number is 9
so the smaller number will be 9 less the difference, or ...
smaller number = 9 - 36 = -27.
Now, you know both numbers, so you know there sum is ..
9 + (-27) = -18 . . . . . sum of the two numbers
_____
You can work it also using L for the larger number, D for the difference. Then the smaller number is (L-D) and the sum is ...
sum = L + (L -D) = 2L - D
Filling in the values given for the larger number and the difference, you have ...
sum = 2·9 - 3·12 = 18 -36 = -18 . . . . . as before
