Which of the following equations is equivalent to 2y+5x=16 A: y=2x+6
B: y= -5/2x +8
C: y=5/2x+8
D: y=2/5x+8

B

Step-by-step explanation:

2y+5x=16

2y=-5x+16

y=-5/2x+8

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

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
