Which ordered pair is a solution to the equation y= 7x-9? (4,19)
(54,9)
(-3,30)
(2,15)

(4,19)

Step-by-step explanation:

Cuz if u substitute these values in for the x and y in the equation, the equation would be true:

1.) 19 = 7(4) - 9

2.) 9 ≠ 7(54) - 9

3.) 30 ≠ 7(-3) - 9

4.) 15 ≠ 7(2) - 9

As you can see, 1st equation is the only equation that's true.

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
