Answer:

D) $x+y=-3$

Step-by-step explanation:

Basically, if you plug in the x and y-coordinates into an equation, both sides should work out to be equal to each other:

Since $-5+2\neq 3$ , we can eliminate choice A

Since $-5-2\neq -3$ , we can eliminate choice B

Since $-5-2\neq 3$ , we can eliminate choice C

Therefore, since $-5+2=-3$ , then D is correct. Also, $3+(-6)=-3$

Karen works for 85 hours over a two week period. SHe earns $1,891.25 over this period. How much does Karen earn for 8 hours of w

Gekata [30.6K]

If karen works 85 hours within two weeks and earns $1,891.25, you'd set up an equation like this, to find the value of x ----

x=amount of money per hour Karen works

85x=<span>1,891.25

then divide </span><span>1,891.25 by 85

x=</span>22.25

this says that karen gets $22.25 for every hour she works.... then to find how much she works for 8 hours you want to multiply the amount of money she gets per hour by 8 hours.

22.25 x 8 = 178

Karen earns $178 after working 8 hours.
