ANSWER
The solution is
EXPLANATION
The given equations are:
and
We multiply equation 1 by 3 to get,
We multiply equation 2 also by 2 to get,
We subtract equation 4 from equation 3 to get,
This implies that,
We put this value of y into any of the equations say equation 2
Simplify
Group like terms
Simplify,
Divide both sides by 3 to get,
Therefore the solution is
The correct answer is option D.
Answer:
x(x+3)(x−10)
Step-by-step explanation:
Hope this was helpful let me know if it was!
If i had to estimate i would say letter D
Answer:
no solution
Step-by-step explanation:
y = -2x + 3
6x + 3y = -3
the substitution method means you plug one equation into the next, because the first equation gives us a solution for y we can go ahead and plug that into y of the second equation
6x + 3(-2x + 3) = -3
6x - 6x + 9 = -3
9 = -3
which is false meaning that there are no solutions and the lines don't touch at any point
