7 0

Answer:

x=0 y=0

Step-by-step explanation:

3x + y = -7y = x

cancel out all y's

3x+ y(0) = -7(0) = x

3x =x

-x -x

2x = 0

divide both sides by 2

x=0

3x + y = -7y =x

cancel out all x's

3(0) +y = -7y = x(0)

y=-7y

-y -y

0 = -7y

divide both sides by -7

y=0

hope this helps!

Select the quadratic equation that has roots x=8 and x=-5

stellarik [79]

Step-by-step explanation:

Since, x=8 and x=-5 are the roots.

Therefore, (x - 8) & (x - 5) will be factors.

Hence, required quadratic equation can be given as:

$(x - 8)(x - 5) =0 \\ \\ \therefore {x}^{2} + ( - 8 - 5) x+ ( - 8) \times ( - 5) = 0 \\ \\ \therefore {x}^{2} + ( - 13) x+ 40= 0 \\ \\ \huge \red{ \boxed{ \therefore {x}^{2} - 13x+ 40= 0 }} \\ is \: the \: required \: quadratic \: equation.$
