Answer:
x= 2
y = 20
Step-by-step explanation:
y = 6x + 8
y = –4x – 2
y = 4 (6x + 8
)
y = 6 (–4x – 2)
y = 24x + 32
y = –24 -12
___________
y = 20
input that back into the equation to find x
20 = 6x + 8
20 - 8 = 6x
12 = 6x
x= 2
height:length
1:2
x feet: 5 feet
You know the length and the ratio of the dimensions. From the ratio you know that the length is twice the height. So height = 5/2 = 2.5 ft.
