Answer:
x=2
y= -2.5
Step-by-step explanation:
x int
1.) set y to 0 (5x -4(0)=10
solve for 5x=10
y int
1.) set x to 0
solve for -4y=10

Step-by-step explanation:
It is saying that 80/100 which is .80, so 50*80%= 40
The coordinates are 8, -3.
Answer:
-4, 5
Step-by-step explanation:
y=f(x)
to find the x intercepts then y must be 0
0=f(x), solutions are x=-8, x=1
when 0=f(x+4), you simply add 4 to each intercept's x coordinate
-8+4=-4
1+4=5
-4, 5
