A computer repair company charges an initial fee plus $40 per hour for repair work. The total cost for 3 hours of work is $150. Assume the relationship is linear. Find and interpret the rate of change and the initial value.

Rate of change = 40

Initial value = 30

Step-by-step explanation:

150 = 3(40) + b

b = 30

I created this equation to mean 150 is the total which comes from 40 per hour (in this case it was 3), and I got the b to equal 30.

The equation shows that the rate of change is 40 and the initial value is 30.

hi! i think the answer is 1/2 : )

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
