Answer:
You don't even need to do the whole question. Just look at 5 times 2x. which is 10x then u get your answer
Answer:
C. When the equations -10x + 5y = -60 and -3x − 5y = -5 are added together, a third linear equation, -13x = -65, is formed, and it shares a common solution with the original equations.
Step-by-step explanation:
2x-y=12
-3x-5y=-5
multiply the first equation by -5
-10x +5y = -60
add the 2 equations together
-3x-5y=-5
-10x +5y = -60
-------------------------
-13x = -65
We use the addition property of equality which says adding the same thing to both sides, doesn't change the equation, so we will get the same answer as the original equation
2x^2 - 2x + 7 = 2(x^2 -x +3) + 1 = 2(x-0.5)^2 + 17/6
