Consider the graph of the quadratic function y = –2(x + 2)2 – 1 with no real zeros. What number can be added to the right side of the equation to change it to a function with one real root?
Answer:
The number is +1
Step-by-step explanation:
we have
[tex]y=-2(x+2)^2-1[/tex]
This is the equation of a vertical parabola with vertex at point (-2,-1)
The function has no real zeros
we know that
If the number +1 is added to the equation on the right side
then
[tex]y=-2(x+2)^2-1+1[/tex] -------> [tex]y=-2(x+2)^2[/tex]
Is a translation one unit up
The vertex of the parabola will be the point (-2,0) and the function will have one real root

Rolando tossed a coin 4 times
Which of the following is a list of all the possible outcomes with 2 or 3 heads?
A. Y
B. Z
C. W
D. X
The possible outcomes of tossing a coin 4 times with 2 or 3 heads can be represented using a tree diagram.
Explanation:The possible outcomes of tossing a coin 4 times can be represented using a tree diagram. Each toss has 2 possible outcomes, either a head (H) or a tail (T). Starting with the first toss, there are 2 branches representing each possible outcome. For the second toss, each branch splits into 2 more branches representing the possible outcomes of the second toss, and so on. To find the outcomes with 2 or 3 heads, we need to count the paths on the tree diagram where there are 2 or 3 branches labeled as heads (H).
Let's label the paths as follows:
Y: HHTT
Z: HTHT
W: HTTH
X: TTHH
These are the possible outcomes with 2 or 3 heads. Therefore, the answer is option B. Z.

The sum of a number, n, and 8 is multiplied by -4, and the result is 12. What is the number?
Answer: -11
Step-by-step explanation:
(n+8)* -4= 12
-8 -8
n* -4= 12
/-4 /-4
n= -11
Based on the calculations, the unknown number (n) is equal to -11.
How to find an unknown number?In this exercise, you're required to find an unknown number (n). Thus, we would translate the word problem into an algebraic expression as follows:
The sum of a number (n) and 8:
n + 8
Multiplying by -4, we have:
(n + 8) × -4 = 12
-4n - 32 = 12
-4n = 12 + 32
-4n = 44
n = -11.

Answer:
The correct answer option is C. Graph Z.
Step-by-step explanation:
We are given that a cereal company finds that the more it spends on advertising, the more boxes of cereal it sells.
It means that the advertising is directly proportional to the number of boxes of cereal sold.
Therefore, the sales of the cereal company can be represented by graph Z where the value of y increases as the value of x increases.

Answer:
B 6x - 4y = 2
Step-by-step explanation:
Stand form of a linear equation is
Ax + By =C
8 - 4(x-y) = 2x+6
Distribute the -4
8 -4x +4y = 2x+6
Subtract 2x from each side
8 -4x-2x +4y = 2x-2x+6
8 -6x +4y = 6
Subtract 8 from each side
8-8-6x+4y = 6-8
-6x+4y = -2
We like to have x with a positive coefficient
Multiply by -1

Answer:
90 cm^2
Step-by-step explanation:
The scale factor between triangle ABC and triangle PQR is 4:6 or 2:3
The scale factor is 2/3
When relating areas, we use the scale factor squared
Area of ABC = scale factor squared * Area of PQR
40 = (2/3) ^2 Area of PQR
40 =4/9 Area of PQR
Multiply each side by 9/4
40 *9/4 = 9/4 *4/9 * Area of PQR
90 = Area of PQR
When we work with lengths of similar figures, we multiply by the scale factor.
When we work with areas of similar figures, we have a length and a width, so we are really multiplying by the scale factor two times, or the scale factor squared.
A = l*w
A = SF (l) * SF (w)
= SF ^2 lw
So the area of the new figure is the scale factor squared times the area of the old figure.
A new = SF^2 A old
To get from the old figure to the new figure we multiply by 6/4 or 3/2
A new = (3/2)^2 (40)
A new = 9/4 * 40
= 90

Step-by-step explanation:
To solve the situation, find the speed per hour they were driving by dividing the distance they drove by the time it took.
Alyssa drove 105 miles in 3.5 hours or 105/3.5 = 30 miles per hour.
Caleb drove 168 miles in 4 hours or 168/4 = 42 miles per hour.
Since they both left at the same time and drove the same 210 miles to the beach, Caleb arrived first since he was driving faster.
He arrived in 210/42 = 5 hours.
Alyssa arrived in 210/30 = 7 hours.
He arrived 2 hours before her.

All of the points are in the right places! :P
Answer:
All four points are in the right place.
Step-by-step explanation:
Here's what you need to check.
The coordinate of each point is a set of two number in a round bracket.
The first number is the x-coordinate of that point. That's the place of the point on the x-axis.The second number is the y-coordinate of that point. That's the place of the point on the y-axis.Taking point A (9, 7) as an example.
x-coordinate of A: 9.y-coordinate of A: 7.The x-axis is the horizontal axis. Find the tick with number "9" on the horizontal x-axis. Draw a vertical line through that tick. The x-coordinate of all points on that vertical line is 9. The y-axis is the vertical axis. Find the tick with number "7" on the vertical y-axis. Draw a horizontal line through that tick. The y-coordinate of all points on that horizontal line is 7.The two lines should intersect at some point on the grid. The x-coordinate of the place where they intersect is 9, and the y-coordinate will be 7. The intersect is the position of point A.Repeat these steps for the rest of the four points. See if every single point is in their place.

HELP PLEASE! what is the inverse of the function f(x)=2x+1
Answer:
The inverse function is a) h(x) = 1/2x - 1/2
Step-by-step explanation:
To find the inverse of any function, start by switching the x and f(x) values.
f(x) = 2x + 1
x = 2f(x) + 1
Now solve for the new f(x). The result will be your inverse function.
x = 2f(x) + 1
x - 1 = 2f(x)
(x - 1)/2 = f(x)
h(x) = 1/2x - 1/2
The inverse of the function f(x)=2x+1 is found by switching x and y in the function to create a new equation, rearranging that equation to solve for y, resulting in the inverse f^-1(x)=(x-1)/2.
Explanation:
To find the inverse of the function f(x)=2x+1, you first switch the roles of x and y in the function.
Instead of f(x)=2x+1, you would write it as x=2y+1. Then, you solve for y in this new equation. To do that, you first subtract 1 from both sides of the equation, giving you x-1=2y. Then, you divide each side by 2: y=(x-1)/2.So, the inverse of the function is f^-1(x)=(x-1)/2.

The cost, in dollars, of a single-story home can be approximated using the formula C- kiw, where i is the approximate length of the home and w is the approximate width of the home. Find the units for the coefficient k.
Its dollar per square foot
The unit for the coefficient 'k' in the equation 'C= kiw', given that 'C' is the cost in dollars and 'i' and 'w' are the dimensions of the home in an area-unit such as feet or meters, should be dollars per square foot or dollars per square meter.
Explanation:The question is asking to find the unit for the coefficient k in the equation 'C= kiw' where 'C' represents the cost of a single-story home, 'i' is the length of the home, and 'w' is the width of the home. In this equation, the cost 'C' is in dollars, and the length 'i' and width 'w' are likely in feet or meters (units of length).
Therefore, the coefficient 'k' must have the units that make the equation dimensionally consistent. In other words, the units of 'k' must be such that when multiplied by area ('iw' is an area), the result is cost. So, the unit for 'k' in this context would be dollars per square foot or dollars per square meter, depending on the units used for 'i' and 'w'.

Step-by-step explanation:
Since it is greater than or equal to, the graph line is a solid line.
Then, since we know that it is greater than, we know that we can shade above the graph line.
To check this, all you have to do is choose a random point in the shaded region and plug it in the equation. If it checks out, it is correct.
Answer:
Graph represented by option C is the correct choice.
Step-by-step explanation:
We are asked to graph an inequality [tex]y\geq2x-3[/tex].
The boundary line of our given inequality will be a solid line as we have greater than or equal to [tex]\geq[/tex] sign.
The boundary line of our given inequality would be [tex]y=2x-3[/tex].
Now, we will test point (0,0) to shade in the correct region as:
[tex]0\geq2(0)-3[/tex]
[tex]0\geq0-3[/tex]
[tex]0\geq-3[/tex]
Since the point (0,0) is a solution for our given inequality, therefore, the shaded area of our inequality will include point (0,0).
