2x+3y=11
x-3y=1
what is the solution (x, y) to the given system of equations?

Step-by-step explanation:

Add both equations up.

(2x + 3y) + (x - 3y) = 11 + 1

3x = 12

x = 4

Now we can find y.

x - 3y = 1

4 - 3y = 1

y = 1

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

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
