Answer:
see below
Step-by-step explanation:
y = 8x − 9
y = 4x − 1
Since the two equations are both equal to y set them equal to each other
8x -9 = 4x-1
Subtract 4x from each side
8x - 9 -4x = 4x-1-4x
4x -9 = -1
Add 9 to each side
4x-9+9 = -1+9
4x = 8
Divide by 4
4x/4 = 8/4
x=2
Now find y
y =4x-1
y = 4(2) -1
y = 8-1
y = 7
(2,7)
The solution to the system of equations is where the two lines intersect. When the two lines are graphed, they will intersect at (2,7)
Answer:
the total difference in height will be 22 inches
Step-by-step explanation:
since the slope is 0.5 inch per foot, and the patio is 44 feet wide, the end of the patio will be 0.5 x 44 = 22 inches lower
the slope measures how much the height (Y axis) will change as the length (X axis) increases by 1 unit. In this case, since the height decreases as the length increases the slope is negative.
