For (x + 4)(x + 9) to equal 0, either (x + 4) or (x + 9) must equal . the values of x that would result in the given expression being equal to 0, in order from least to greatest, are and . nextreset

the value of x are -9, -4

Step-by-step explanation:

For (x + 4)(x + 9) to equal 0, either (x + 4) or (x + 9) must equal . The values of x that would result in the given expression being equal to 0

To find value of x , we set each factor =0 and solve for x

Subtract 4 from both sides

x=-4

Subtract 9 from both sides

x=-9

So the value of x are -9, -4

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
