The answer will mostly be true if you know the answers
I think the answer is A) 16 inches because they are basically a dilation of the pre-image.
Answer:
y = (x - 2)² - 9 Vertex form
y = x² - 4x - 5 Standard form
Step-by-step explanation:
vertex = (h, k) = (2, -9)
Vertex form
y = a(x - h)² + k
y = a(x - 2)² - 9
find "a" using point (5, 0)
0 = a(5 - 2)² - 9
0 = a(3)² - 9
0 = 9a - 9
9 = 9a
a = 1
y = (x - 2)² - 9
Standard form
y = (x² - 4x + 4) - 9
y = x² - 4x - 5
Answer:
61 cm for each book shelf.
Step-by-step explanation:
First it gives you the width of the boxes so you add them together
132 + 108 + 94 = 334
so 334 cm has already been used out of 456 cm.
Next you will 456 - 334 = 122 cm left over
if they are building 2 book cases you with take what cm's you have left and divide it by 2
122 / 2 = 61
So that means each book case will be 61 cm's wide
