Zuleika was solving 2(x - 3) - 9 = 3x - 9. zuleika's first step resulted in 2(x - 3) = 3x
because she used the multiplication/addition property of equality. the second
step resulted in 2x - 16 = 3x because she collected like terms used the distributive
properly. in the next two steps, zuleika used the addition/multiplication property
twice to get -x = 6.she then found the solution, x = -6, by using the
addition/multiplication property of equality.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
