Whats the answer im confused

(-2,3)

Step-by-step explanation:

y=x+5       y=−2x−1

Solve y=x+5 for y:

Substitute x+5 for y in y=−2x−1:

y=−2x−1

x+5=−2x−1

x+5+2x=−2x−1+2x (Add 2x to both sides)

3x+5=−1

3x+5+(−5)=−1+(−5) (Add -5 to both sides)

3x=−6

3x    =  -6       (Divide both sides by 3)

3           3

x=−2

Substitute −2 for x in y=x+5:

y=x+5

y=−2+5

y=3 (Simplify both sides of the equation)

Therefore, x= -2 and y=3

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
