Answer:

x=9

Step-by-step explanation:

Set the function equal to 75 and solve for x.

75=10x-15

add 15 to each side

90=10x

divide each side by 10 to isolate x

9=x or x=9

Answer:

x = 9

Step-by-step explanation:

f(x) = 10x - 15

f(x) = 75

Plug in 75 for f(x)

75 = 10x - 15

add 15 from either side

90 = 10x

divide either side by 10

9 = x

4a-b<br> Evaluate the expression when a=5 and b=-7
stepladder [879]

Answer:

27

Step-by-step explanation:

So first we need to plug in 5 as the variable a and -7 as the variable b

4(5)-(-7)

Next we multiply the 4 and the 5 together to get 20

4(5) = 20   or    4 x 5 = 20

20-(-7)

Now we subtract negative 7 from 20

20-(-7) = 27

This can also be written as 20 plus 7 as a mathematical rule states: two negatives make a positive. So:

20-(-7) = 20 + 7

Both of these are equivalent in every sense of the word and give us our final answer of 27
