Asystem of equations is shown below. find the solution by using substitution.

y=3x+6
y=x+2

a) (-2, 0)

b) (0, -2)

c) (0, 2)

d) (2, 0)

a)

Step-by-step explanation:

x + 2 = 3x + 6

-3x - 3x

___________

−2x + 2 = 6

- 2 - 2

_________

4 = −2x

_ ___

−2 −2

[Plug this back into both equations above to get the y-coordinate of 0];

I am joyous to assist you anytime.

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

i believe the answer is the polygon, heptagon.
