Answer:

B. -7

Step-by-step explanation:

f(x) = 4x + 5

To find the value of f(-3), replace all the x's in f(x) with -3.

f(x) = 4x + 5

f(-3) = 4(-3) + 5

f(-3) = -12 + 5

f(-3) = -7.

This makes your answer B, -7.

The sum of three numbers is 27 the second number is three times the first while the third is twice the first find their average

Leviafan [203]

Answer:

Step-by-step explanation:

x = first number

3x = second number

2x = third number

27 = x + 3x+ 2x

27 = 6x

x=4.5 (first number)

3(4.5) = 13.5 (second number)

2(4.5) = 9 (third number)

(4.5 + 13.5 + 9) /3 = 9

Wow after doing all that I realized that all you had to do was 27/3 since there's 3 numbers.
