Answer:
(D) (3+6)/(2+1)
Step-by-step explanation:
None of the above is the correct choice
Answer:
C
Step-by-step explanation:
We can multiply each equation by a constant so they'll equal either 15 or -15 since that is the LCM.
Since the answer choices want us to make the top a negative 15, we'll do that.

To make the y's cancel out, the second equation would have to have the y's coefficient equal 15.
Let's do that.

So the resulting equations are answer choice C.
Answer:
Domain is also called input you got this
Step-by-step explanation:
The slope is m, which is 312.3
also in intercept form would be y=312.3x+18.5
