Answer:

$h(x) = 57(0.8)^x$

Step-by-step explanation:

Given

$f(x) = 32(0.8)^x$

$g(x) = 25(0.8)^x$

Required

A function that represents the total resale value of the two vehicles

To do this, we simply add up the functions

$h(x) = f(x) + g(x)$

$h(x) = 32(0.8)^x + 25(0.8)^x$

Factorize

$h(x) = (32 + 25)(0.8)^x$

$h(x) = 57(0.8)^x$

Answer:

Step-by-step explanation:

The closed circle at - $\frac{3}{2}$ indicates that x can equal this value

The open circle at $\frac{7}{2}$ indicates that x cannot equal this value.

All values of x between - $\frac{3}{2}$ and $\frac{7}{2}$ are valid, thus

- $\frac{3}{2}$ ≤ x < $\frac{7}{2}$ → B

After how many years are the salaries offered by Company A and Company B the same?

iren2701 [21]

Answer:

Step-by-step explanation:

24,000 = 24 thousands

30,000 = 30 thousands

3,000 = 3 thousands

2,4000 = 2.4 thousands

"x" years

24 + 3x = 30 + 2.4x

3x - 2.4x = 30 - 24

0.6x = 6

x = <em>10 years</em>
