5/3 is a root of f(x) = (3x + 5) (x2 - 6x + 9)2 = 0 true false

For this case we have the following function:

To find the roots we must equal the function to 0, that is:

So:

Subtracting 5 from both sides:

Dividing between 3 on both sides:

Thus, one of the roots is

True

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
