Given the function f(x) = 2 x + 61 - 4, for what values of x is f(x) = 6? O x= -1, x = 11

Ox=-1, x = -11

O x= 14 = -26

O x= 26, x=-14

or

Step-by-step explanation:

Given

Required

Find x when

Substitute 6 for f(x)

Add 4 to both sides

Divide both sides by 2

Rewrite as:

This can be split to:

or

Solve for x in both cases

step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
