Answer:

a. 440

b. 100

c. 1800

d. 320

Step-by-step explanation:

a. $7000 is 3000 +4000 so this falls in two pay ranges.

0.04(3000) + 0.08(4000) = 120+320 = $440

b. $2500 is lower than 300 so it falls in only one pay range.

0.04(2500) = $100

c. 12,000 is greater than both 3000 and 8000 so this falls in the last pay range.

0.15(12000) = $1800

d. $5500 is 3000+2500 so this falls in two pay ranges.

0.04(3000) + 0.08(2500) = 120+200 = $320

Which equation represents the line that passes through points (1 -5) and (3 -17)

Fynjy0 [20]

Answer:

6x-11

Step-by-step explanation:

m=y2-y1

x2-x1

-17--5 = -12

3-1. -2

The two negatives cancel ❌

m=12

Divide by 2

m=6

y=mx+b

-5= 6 (1) + b

-5= 6 + b

Subtract (6) from both sides

b= -11

The equation for the line is 6x -11

Look at the graph of f(x)=x^2+6x+10. What is the average rate of change between {1,3}?

nydimaria [60]

This equals [f(3) - f(1)] / [3-1]

= 3^2 + 6(3) + 10 - (1^2 + 6(1) + 10) / 2
