Answer:
C is the answer
Step-by-step explanation:
10x=180-140
so,x=40÷10=4answer
Since both are equivalent to y, the equations must be equivalent.
x^2-x-3= -3x+5
x^2+2x-8=0
(x+4)(x-2)=0
x=-4, x=2
Plug the values of x in to either equation
y=-3(-4)+5
y= 12+5
y=17
y= -3(2)+5
y=-6+5
y=-1
Final answer: (-4,17) and (2,-1)
7.0, 7.2, 7.4, 7.6, 7.8, 8.0, 8.2, 8.4
