Pre Calc Question for one of my classes

Mathematics
1 answer:
Tatiana [17]2 years ago
5 0

Answer:

Step-by-step explanation:

f(x) is like y in a linear equation. There is one major difference. F(x) tells you what to substitute on the right every time you see an x.

f(a) = -3a + 7

f(b) = -3b + 7

For this question a and b have values. Now work with the right side only. This is the quickest way to get the answer, but it is only marginally correct.

f(a) = -3(-8) + 7 = 24 + 7 = 31

f(b) = -3(7) + 7 = -21 + 7 = - 14

f(a) + f(b) = 31 - 14 = 17

f(a) - f(b) = 31 - (-14) = 31 + 14 = 45

Which method correctly solves the equation using the distributive property? Negative 0. 2 (x minus 4) = negative 1. 7 Negative 0
xenn [34]

The method which is used to solve the provided equation using the distributive property is,

\rm x = 4 + 8.5 = 12.5

<h3>What is distributive property?</h3>

The distributive property is to make something easier to do or understand and to make something less complicated.

The given expression is \rm - 0.2(x-4) = -1.7.

The expression can be written as

\rm 0.2(x-4) = 1.7

Divide both sides by 0.2

\rm x-4 = \dfrac{1.7}{0.2} = 8.5

Add 4 both sides, we have

\rm x = 4 + 8.5 = 12.5

Thus, the value of x is 12.5.

More about the distributive property link is given below.
