Determining the Input Using an Equation f(x) = x + 7 A 2-column table with 4 rows. The first column is labeled x with entries negative 3, negative 1, 1, 3. The second column is labeled f of x with entries 8, StartFraction 22 Over 3 EndFraction, StartFraction 20 Over 3 EndFraction, 6. Determine the input that would give an output value of . = x + 7 = x x =

i dony know

step-by-step explanation:

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

the answer is b.
