Answer:
y = 6x
Step-by-step explanation:
For a vertical stretch, you simply multiply x by the factor you want to stretch it by. 3x • 2 is 6x.
Answer:
d. 64
Step-by-step explanation:
x^2+16x
The coefficient of the x term is 16
Divide by 2
16/2 =8
Then square it
8^2 = 64
We add 64
x^2 +16x +64
(x+8)^2
Answer:
Step-by-step explanation:
The two angles are formed from 2 intersecting lines. The angles are called vertically opposite angles. They are equal
4x + 21 = 85 Subtract 21
4x = 85 - 21 Combine
4x = 64 Divide by 4
x = 64/4
x = 16
Which of what? you didn't put the question.
First look at the given numbers, especially 123 degrees which if you add up the other side it equals 180 degrees so:
180-123= 57
Ok now you know two sides of the triangle and you know that all the 3 sides add up to 360 degrees so:
57+75= 132
180-132= 48
