Answer:
a would be correct
Step-by-step explanation:
Answer:
x = -2
y = -5
Step-by-step explanation:
We can solve this algebraically (substitution or elimination) or graphically. I will be using elimination:
Step 1: Add the 2 equations together
-8y = 40
y = -5
Step 2: Plug <em>y </em>into an original equation to find <em>x</em>
-3(-5) + 10x = -5
15 + 10x = -5
10x = -20
x = -2
And we have our final answers!
Answer: x^2 = 2
Step-by-step explanation: 3x^2 + 4x=12
6x^2=12
x^2= 12/6
x^2= 2
Since both 3x and 6x have the variable x in it, we can just go ahead and add 3 and 6.
3x+6x=9x
