Slove the systems of equations: 1. y=-x-1
y=3/2x-6
a(2,3)
b(2,-3)
c(-3,-3)d
d(-2,3)

2. y=-4x-9
y=-2/3x+1
a(3,3)
b(-3,-3)
c(3,-3)
d(-3,3)

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

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
