What is the midpoint (M) of a segment whose endpoints are A (0,0) and B (4, 8)

(2,4)

Step-by-step explanation: 0+4 over 2, 8+10 over 2.

Add 0 and 4 which is 4, divided by 2 equals 2, for the x coordanite. Add 8 and 10 which is 8, divided by 2 equals 4, for the y coordanite.

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
