Answer:
1
Step-by-step explanation:
3x+2y=8
x=2y
3(2y)+2y=8
6y+2y=8
8y=8
y=1
x=2(1)
x=2
x-1=2-1
x-y=1
Answer:
y = 12
x = 10/3
Step-by-step explanation:
y = -3.6x + 12
From this equation, which is in slope intercept form (y = mx+b), we already know that b represents the y-intercept, so that means the y-intercept is 12.
To find the x-intercept, we need to make y equal 0 to find x. So:
0 = -3.6x + 12
-3.6x = -12
x = 3.33333 --> 3 1/3
x = 10/3
Answer:
Step-by-step explanation:
The center is at (2,-7). The radius is 2.
(x-2)² + (y+7)² = 2²
These points are reflective off of the y-axis. (9,2/5) reflected over the y-axis is (9,-2/5)
The area of the side walk would be 5.5ft^2. Hope this helps
