<span>5x-6y=-15
5x+6y=12
---------------add
10x = -3
x = -3/10
x = -0.3
</span>5x+6y=12
5(-0.3) + 6y = 12
6y = 12 + 1.5
6y = 13.5
y = 13.5 / 6
y = 2.25
Answer:
250 MAYBE
Step-by-step explanation:
The answer is C.
It has a negative slope (-40) and a y-intercept at 200.
Using the factor label method, you would set up your ratio like so:
2-x is not a polynomial so there fure its the 3rd choice which is c
