Answer:
x=-2.5,9
Step-by-step explanation:
Set them equal to each other to say 2x^2-9x=4x+45. Get them all on one side to get 2x^2-13x-45. Factor that out to get (x+2.5)(x-9). Set that equal to 0 to get x=-2.5,9
2x-2y=-6
-2y= -2x-6
y=x+3
Y-intercept= 3
X-intercept= -3
19
9+10=19
True
x=5+7=12
The only solution is x=12.
