Answer:

This is true when f is less than 83 and false when f is equal to or greater than 83

Step-by-step explanation:

67>f-15

Add 15 to each side

67+15>f-15+15

83 > f

This is true when f is less than 83 and false when f is equal to or greater than 83

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes.y=-2/5x+11/5

ivanzaharov [21]

Answer:

y-intercept (0,11/5)

x-intercept (11/2,0)

Step-by-step explanation:

The y-intercept is obtained when the x-coordinate equals 0 (x=0)

so the y-intercept is (0,11/5)

The x-intercept is obtained when the y-coordinate equals 0 (y=0)

In this case

0 = -(2/5)x+11/5---->(2/5)x = 11/5 ----> x=(5*11)/(5*2) = 11/2

So the x-intercept is (11/2,0)
