Solve each system of equations

(-2,-2)

Step-by-step explanation:

Let's solve your system by substitution.

y=2x+2;y=−2x−6

Step: Solvey=2x+2for y:

y=2x+2

Step: Substitute2x+2foryiny=−2x−6:

y=−2x−6

2x+2=−2x−6

2x+2+2x=−2x−6+2x(Add 2x to both sides)

4x+2=−6

4x+2+−2=−6+−2(Add -2 to both sides)

4x=−8

4x/4

=

−8/4

(Divide both sides by 4)

x=−2

Step: Substitute−2forxiny=2x+2:

y=2x+2

y=(2)(−2)+2

y=−2(Simplify both sides of the equation)

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
