Question

for each value of v, determine whether it is a solution to -8(v + 4) = -48.
is it a solution?
yes no
v 5 -10 -3 2
(there are also some buttons and a table with radio buttons for each value to choose yes or no)

Explanation:

Step1: Test \( v=1 \)

Substitute \( v=1 \): \( -8(1+4) = -8×5 = -40 ≠ -48 \) → No

Step2: Test \( v=5 \)

Substitute \( v=5 \): \( -8(5+4) = -8×9 = -72 ≠ -48 \) → No

Step3: Test \( v=-10 \)

Substitute \( v=-10 \): \( -8(-10+4) = -8×(-6) = 48? \) Wait, correction: Wait, original equation is \( -8(v+4)=-48 \). Divide both sides by -8: \( v+4=6 \) → \( v=2 \). Oh, mistake earlier: Test \( v=-10 \): \( -8(-10+4)=-8×(-6)=48≠-48 \). Test \( v=2 \): \( -8(2+4)=-8×6=-48 \) → Yes.

Step4: Test \( v=-3 \)

Substitute \( v=-3 \): \( -8(-3+4)=-8×1=-8≠-48 \) → No

Step5: Test \( v=2 \)

Substitute \( v=2 \): \( -8(2+4)=-48 \) → Yes

Corrected Answer:
For \( v=1 \): No
For \( v=5 \): No
For \( v=-10 \): No
For \( v=-3 \): No
For \( v=2 \): Yes

(Note: Initial miscalculation fixed—only \( v=2 \) satisfies the equation.)

Answer:

For \( v = 1 \): No
For \( v = 5 \): No
For \( v = -10 \): Yes
For \( v = -3 \): No
For \( v = 2 \): No
