Step-by-step explanation:
-4/3x-6=-26
The first step is to add 6 to each side
-4/3x-6+6=-26+6
-4/3x =-20
Now multiply by -3/4 to isolate x.
-3/4 * -4/3x = -3/4 * -20
x = 60/4
x = 15

A relation is plotted as a linear function function on the coordinate plane starting at point E at (0,27) and ending at point F at (5, -8) what is the rate of change for the linear function and what is its initial value ? Select from the drop down menus to correctly complete the statement.
The rate of change for the linear function is choose -7, 0, 7, 27 and the initial value is, choose, -8 , -5, 0, 27
Thank You!!! :)
Answer:
see explanation
Step-by-step explanation:
the rate of change is the measure of the slope m of the line
To calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 27) and (x₂, y₂ ) = (5, - 8)
m = [tex]\frac{-8-27}{5-0}[/tex] = [tex]\frac{-35}{5}[/tex] = - 7 ← rate of change
the initial value is the y-coordinate of the starting point
That is y = 27 ← starting value
The rate of change for the linear function is -7 and the initial value is 27.

Ramon bought a bicycle for $478. The value of the bicycle is expected to decrease at a rate of 6.5% each year. Which function equation represents the value of the bicycle after t years? f(t)=478(0.935)^t
f(t)=478(0.065)^t
f(t)=478(6.5)^t
f(t)=478(1.065)^t
Answer:
Correct choice is A
Step-by-step explanation:
Note that 6.5% is 0.065 as decimal.
Ramon bought a bicycle for $478. The value of the bicycle is expected to decrease at a rate of 6.5% each year, then the function that represents the situation is
[tex]y=478\cdot (1-0.065)^t=478\cdot (0.935)^t,[/tex]
where t is time (in years).
Options C and D are false, because functions are increasing, option B is false, because this function represents how much will the value decrease.
Answer:
The correct answer is A
f(t)=478(0.935)^t
Determine the measure of q in sin q =0.4848 to the nearest degree.
Answer:
see explanation
Step-by-step explanation:
there are 2 possible values for q
Since sin q > 0 then q is in the first or second quadrant
sin q = 0.4848, then
q = [tex]sin^{-1}[/tex](0.4848) ≈ 29° ← first quadrant
or q = 180° - 29° = 151° ← second quadrant

which of the following is not true in a dialation?
The statement outlined in the question is not related to mathematical dilation, hence it is not true. In mathematics, a dilation is a transformation that modifies the size of a figure, but not its shape. It can enlarge or reduce the figure while preserving orientation and parallelism of lines.
Explanation:The question is about dilation in the context of mathematics, particularly geometry. Here, the provided option, 'The contraction of the uterus during childbirth and lactation will not take place, causing problems and complications in the mother,' is not related to mathematical dilation. So, the statement is not true in a dilation.
In Mathematics, dilation is a transformation that changes the size of a figure without altering its shape. It can be a reduction (making the figure smaller) or an enlargement (making the figure larger). The characteristics of dilation include preserving the shape, altering the size, and maintaining the same orientation and parallelism of lines.

Find the value of x when the expression 6x+9 equals 3x+6
Answer: 1=x
Step-by-step explanation:
6x+9=3x+6 -6 -6
6x+3=3x -6x -6x 3=-3x 3 divided by 3 is one 1=x I hope this helps sorry if its incorrect i havent done this in a while
Answer:
x = -1
Step-by-step explanation:
Subtract 3x from both sides
6x + 9 - 3x = 3x + 6 - 3x
3x + 9 = 6
Subtract 9 from both sides
3x + 9 - 9 = 6 - 9
3x = -3
Divide both sides by 3
3x/3 = -3/3
x = -1

The number p and −1.2 are additive inverses. Drag and drop −1.2 and p to their correct positions on the number line. Drag and drop the label “Sum” to the sum of −1.2 and p.
Answer:
Value of p is 1.2.
Now drag and drop the values as per explanation.
Step-by-step explanation:
Additive inverse of any number means a number which can be added to the original number to get
Two numbers are said to be additive inverse of each other if sum of both numbers is 0. For example if 5 is the given number then -5 will be it's additive inverse. So to find additive inverse, we basically change the sign of number.
Given number p is additive inverse off -1.2 so p must be 1.2.
Sum will obviously be 0.
So to graph them on number line, we make a point at -1.2, 1.2 and at 0 for their sum.

500
Step-by-step explanation:
Either Table L or Table M shows a proportional relationship. (Table L) - X -1,0,1,2 and Y= -2,0,2,4. (Table M- )X= -1,0,1,2, and Y= -4,0,6,9. Plot the points from the table that shows a proportional relationship.
Answer: Table L shows a proportional relationship.
Step-by-step explanation:
in table L, the ordered pairs are: (-1,-2),(0,0),(1,2),(2,4)
in table M, the ordered pairs are: (-1,-4),(0,0),(1,6),(2,9)
Notice that in table L, the increment for x values is consistent which is adding 1 and the increment for y values is consistent too which is adding 2. That's why table L is proportional.
In table M, the increment for x values is 1 but there is no consistent increment for y values.
What is the equation of the line with a y-intercept of -3 and slope of 2? Write the equation in slope intercept form.
Answer:
Y=2x-3
Step-by-step explanation:
Hi there! :)
Answer:
y = 2x - 3
Step-by-step explanation:
The slope intercept equation looks like this : y = mx + b
Where "m" is the slope and "b" is the y-intercept.
Your y-intercept = -3 → SO, b = -3
Your slope = 2 → SO, m = 2
Replace the values of "b" and "m" in the equation, and you're done:
y = mx + b
y = 2x - 3
There you go! I really hope this helped, if there's anything just let me know! :)
A breakfast cereal is available in four different sizes. Which is the best buy ?
A. 10-ounce box for $2.80
B. 16-ounce box for $3.75
C. 24-ounce box for $4.50
D. 30-ounce box for $5.25
Answer:
D. 30-ounce box for $5.25 is the best buy
Step-by-step explanation:
To determine which is the better buy, we need to determine the unit rate for each. We will take the price and divide by the number of ounces. The best price is the smallest price per ounce.
A. 10-ounce box for $2.80
$2.80/10 = $.28 per ounce
B. 16-ounce box for $3.75
$3.75/16 = $.234375 per ounce
Rounding to the nearest cent
$.23 per ounce
C. 24-ounce box for $4.50
$4.50/24 = $.1875 per ounce
Rounding to the nearest cent
$.19 per ounce
D. 30-ounce box for $5.25
$5.25/30 =$.175 per ounce
Rounding to the nearest cent
$.18 cent per ounce
The grill was regularly priced at $58, but Jared had a coupon for 25% off. How much money did Jared save by using his coupon?
Answer:
He saves $14.50
Step-by-step explanation:
We can find the discount by multiplying the price by the percentage off
58* .25 = 14.50
He saves $14.50
Answer:
14.50
Step-by-step explanation:
You are not asked for the final price. You are asked for the amount saved. Don't confuse the two.
If he gets 25% off then you multiply (25/100) times 58 to get the amount saved.
(25/100) * 58 = 14.50
So his reduction is $14.50
A school paid $45.00 for 8 toothbrushes and 4 tubes of toothpaste. If each tube of toothpaste cost $4.50, how much did each toothbrush cost? Round to the nearest cent.
Answer:
$3.38
Step-by-step explanation:
The formula is 45= 8x + 4t. Each tube of toothpaste is 4.50, so times four is 18. So they spent 18 dollars on toothpaste, and the rest on toothbrushes. There are 27 dollars left, and 8 toothbrushes, so divide and each toothbrush is $3.375, or $3.38
Answer:
$3.38 PLEASE GIVE BRAINLIEST
Step-by-step explanation:
4.50(4) + 8x = $45.00
$18 + 8x = 45.00
8x = 45 - 18
8x = 27
x = 27 ÷ 8
x = 3.375 rounded to nearest cent is $3.38

Answer each question. What is 35% of 90x? What percent of 16x is 9x?
Answer:
35% of 90x = 31.5
16x is 9x =
Step-by-step explanation:
35 /100 x 90 = 31.5
Answer:
31.5x; 56.25%
Step-by-step explanation:
For the first question:
We can write 35% as 0.35; this is because 35% = 35/100 = 0.35. Taking a percentage of a quantity means we multiply; this gives us
0.35(90x) = 31.5x
For the second question:
To find the percentage the second quantity is of the first one, we divide:
9x/16x = 0.5625
This is the same as 56.25%.
