Match the system with the number of solutions. One solution

No solution

Many solution (infinite solutions)

2x + 4y = 8

2x + 4y = -6

x + y = 7
2x + 2y = 14

y = 3x +1
y = -x +13
need help asap

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

the first option i believe

step-by-step explanation:

160 cm

step-by-step explanation:

you have to add all the sides together
