write the coordinates of the vertices after a reflection over the line x=-2
d(-10,0)
e(-10,2)
f(-5,2
g(-5,0)
Given:
The vertices are d(-10,0), e(-10,2), f(-5,2) and g(-5,0).
To find:
The coordinates of the vertices after reflection over the line x=-2.
Solution:
If figure reflected over the line x=a, then
[tex](x,y)\to (2a-x,y)[/tex]
Here, the figure is reflected over the line x=-2, then
[tex](x,y)\to (2(-2)-x,y)[/tex]
[tex](x,y)\to (-4-x,y)[/tex] ...(i)
Now,
For point d,
[tex](-10,0)\to (-4-(-10),0)[/tex]
[tex](-10,0)\to (-4+10,0)[/tex]
[tex](-10,0)\to (6,0)[/tex]
Similarly,
For point e,
[tex](-10,2)\to (-4-(-10),2)=(6,2)[/tex]
For point f,
[tex](-5,2)\to (-4-(-5),2)=(1,2)[/tex]
For point g,
[tex](-5,0)\to (-4-(-5),0)=(1,0)[/tex]
Therefore, the coordinates of vertices after a reflection over the line x=-2 are d prime (6,0), e prime (6,2), f prime, (1,2) and g prime (1,0).

When the question asks for rate of growth in a linear equation, we are going to look for slope. Slope formula is (y2-y1)/(x2-x1). We are given the points (2,5) and (5,8).
Now we can plug them into our formula:
(5-8)/(2-5)
-3/-3
1
Therefore, our rate of growth, or slope, is 1.

How many units away are each of the points from the y-axis?
O 2
O 3
O 4
O 5
PLEASE HURRY
Answer:
A. 2
Step-by-step explanation:
Point A is on the y-axis is y = -2.
-2 is 2 units away from 0, which is the y-axis.
Point B also, on the y-axis, is y = 2.
2 is also 2 units apart from the y-axis, which is y = 0.
Therefore, both points are 2 units away from the y-axis.

7x + 24 = 3x + 92
4x + 24 = 92
4x = 68
x = 17
then...
<A = 7(17) + 24
119 + 24
<A = 143 degrees
Answer:
then m<A=7×17+24=143
Step-by-step explanation:
7x +24=3x+92(corresponding angles )
7x_3x=92_24
4x=68
x=68÷4
x=17
Alicia runs for exercist. If Alicia runs 8 miles in 6 days, how many days does it take her to run 36 miles? A 32 b 48 c 24 d 27
Answer:
It takes 27 days
Step-by-step explanation:
We will cross multiply
8/36 = 6/x
216= 8x --- next we will isolate our variable x, therefore you'll divide both sides by 8
216/8 = 8x/8
x = 27

11 Three friends rode their bikes last week.
• Christine rode her bike 27 kilometers.
• Philip rode his bike 12 kilometers less than Christine.
Nathan rode his bike 3 times as far as Philip.
Which equation represents n, the distance in kilometers Nathan rode his bike?
A (27 + 12) = 3 = n
B (27-12) x 3 = n
C (27 - 12) 43=n
D (27+12) 3-n

Explain how the location of the vertex and the direction of the opening (upwards or downwards) affects the domain and range of the quadratic function. Use complete sentences.
Answer:
Following are the solution to this question:
Step-by-step explanation:
Its vertex position, as well as the position of its opening, influence its quadratic function set. Its y-coordinate of its vertex (v) and then all values of current above it are included in scope whenever the direction of openings becomes up therefore, the lowest y-value becomes possible.
It implies the scope is y >=v. If it sets up, then, y-coordinate of its vertex was its highest y value available, from all y-values above too y <= v. The scope of a quadratic function, as it will continue forever to left and right, from the negative to positive infinity.plsss help me:(! Write a real world problem for each inequality 5x – 50 100

Find the slope of the line that passes through the ordered pairs (-2,8) and (-9,19)
Answer:
slope: -11/7
Step-by-step explanation:
Slope is equal to the change in yy over the change in xx, or rise over run.
m=change in ychange in xm=change in ychange in x
The change in xx is equal to the difference in x-coordinates (also called run), and the change in yy is equal to the difference in y-coordinates (also called rise).
m=y2−y1x2−x1m=y2-y1x2-x1
Substitute in the values of xx and yy into the equation to find the slope.
m=19−(8)−9−(−2)m=19-(8)-9-(-2)
Simplify.
m=−11/7
Answer:
[tex]m=-1\frac{4}{7}[/tex]
Step-by-step explanation:
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(-2,\:8\right),\:\\\left(x_2,\:y_2\right)=\left(-9,\:19\right)\\\\m=\frac{19-8}{-9-\left(-2\right)}\\\\m=\frac{11}{-9+2}\\\\m=\frac{11}{-7} \\\\m=-\frac{11}{7}\\\\m=-1\frac{4}{7}[/tex]
Cameron wants to buy a skateboard. he has $89, Which is $17 more than he needs. Which equation can be used to determine how much the skateboard costs
Answer:
The answer to this question is $72. The equation is x + 17 = 89
Step-by-step explanation:
Equation: x + 17 = 89
Cameron has $89 so 89 would go behind the equal sign.
He has 17 dollars more than he needs. Whenever more is used that usually indicates that it will be a plus sign. So we will do + 17 = 89.
Finally we need to add the x to complete the equation. This will be shown as x + 17 = 89.
If you solve this equation it will equal x = 72.
If this helped you please subscribe to The Game Rater. Thank you.
Answer:
89-17
Step-by-step explanation:
To find how much Cameron’s skateboard costs you need to take away 17 from your starting amount as you have more. Meaning we subtract the 17 to find how much the skateboard costs.
