What property is used to rewrite (x + 2)(y + z) as y (x + 2) + z (x + 2)
andreyandreev [35.5K]

Answer:

<u>Distributive Property</u>

Step-by-step explanation (if you were to show the steps):

(x+2)(y+z)   <u>(first expression)</u>

xy + xz + 2y + 2z <u>(Distributive Property of Multiplication)</u>

yx + 2y + zx + 2z <u>(use the Commutative Property of Addition and Commutative Property of Multiplication to group xy (also known as yx) and 2y together, and to group xz (also known as zx) and 2z together)</u>

y(x + 2) + z(x + 2) <u>(use factoring to get the rewritten expression at the end)</u>

Joe’s dad works 45 hours per week. He receives a weekly salary of $850, plus a 3.5% commission on sales over $6,500. Given the f
Snowcat [4.5K]

Answer:

f(x) * g(x)

Step-by-step explanation:

Hours worked per week = 45 hours

Weekly salary = $850 plus ;

3.5% commission on sales above $6,500

Given the functions :

f(x) = 0.035x and

g(x) = x - 6,500

and the fact that Joe’s dad sold enough this week to earn commission, which composition function represents Joe’s dad’s commissions ?

Commission = 3.5 / 100 = 0.035

Let his sales for the week = x ; since his sales exceeds 6,500

Hence, sales on which commission is payable is x - 6,500

Hence, commission for the week :

0.035 × (x - 6,500)

f(x) = 0.035 ; g(x) = (x - 6,500)

Composition function:

f(x) * g(x)
