Answer:
5(x^2−8
Step-by-step explanation:
There you go
Answer:
The scale factor is 0.5
It is a reduction
Step-by-step explanation:
∵ The length of the side of the first Δ = 3.4
∵ The length of the side of the second Δ = 1.7
∵ 1.7/3.4 = 1/2 = 0.5
∴ The scale factor is 0.5
∵ The second Δ is smaller than the first Δ
∴ It is a reduction
You can use the slope formula to get this, y=3/4x+1/4
To find the midpoint, you can think of it logically or use the formula. I will explain logically. To do this, first find the distance between the x values and the y values. The distance in x values is 4 and the distance in y values is 2. Then to get the middle, you should divide each by 2 and then add those values to the one that is lower and more onto the left so you get the midpoint as (-5,7)
