Solve the following system using the SUBSTITUTION method.<br> x - 3y = 2<br> 2x - 6y = 6

notka56 [123]

ANSWER:

x – 3y = 2 ...(1)
2x – 6y = 6 ...(2)

On solving eq(1), we get

x – 2 = 3y
x – 2/3 = y

Plug the value of x in eq(2)

2x – 6(x - 2/3) = 6
2x – 2(x – 2) = 6
2x – 2x + 4 = 6
0 = 6 – 4
0 ≠ 2

So, given system of equations is not correct.

Solve for the x-max or h :\
$-b/(2a)=-8/(2*-2)=2=k$
plug it in to equation to get k:/
$y(2)=-2(2)^2+8(2)+3$
-8+16+3=11=k
$y=a(x-2)^2+11
$
solve for a by pluging (0,0)
then a= -11/4
$y=-11/4(x-2)^2+11$
