So if we want to know the common solution(s) to a system of 2 equations, So we can just set both equations equal to each other and solve for the x value(s). That’s where I start below;
2x^2-13x+21 = 2x^2+9x-56
2x^2 cancels out and moving everything to one side and anything with an x variable to the other side we have then;
-22x=-77
22x=77 by cancelling the negative signs
x=77/22 therefore x=7/2 or 3.5
Hope this helps you. Any questions please ask.
Answer:
y=12.5h+3.8 h
=
0.08
y
−
0.304
Step-by-step explanation:
I think that is the answer
Yes it’s correct because 9 is x and if you substitute you do 9 x -9 which gives you y and is -81
36/100 since there's two placement digits, we would then find the GCF (Greatest Common Factor) in this case it's 4, leaving us with 9/25 as our answer.
