4. The value of the x-intercept for the graph 4x - 5y =40 is:

x = 10

Step-by-step explanation:

To find the x- intercept let y = 0 in the equation and solve for x

Given

4x - 5y = 40, then

4x - 5(0) = 40, that is

4x = 40 ( divide both sides by 4 )

x = 10

Thus the y- intercept = 10 ⇒ (10, 0) ← coordinates of y- intercept

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19
