1 |
Problem |
Find the multiplicative Inverse of x: |
|
2 |
Step |
Let’s solve for x |
3x + 12 = - 5 |
3 |
Step |
To simplify the equation, subtract 12 from both sides |
3x + 12 - 12 = - 5 - 12 \$ 3x = (- 17) \$ \$ x = - (17/3) \$ |
4 |
Formula: |
The multiplicative inverse of |
\$ a/b \$ = \$ b/a \$ |
5 |
Step |
Now, the multiplicative inverse of \$- (17/3)\$ is simply its reciprocal: |
Multiplicative inverse of \$ - (17/3) = - (3/17) \$ |
6 |
Choice.A |
This is the correct choice for the multiplicative inverse of the given expression |
\$- (3/17)\$ |
7 |
Choice.B |
This option represents the reciprocal of the correct answer. It’s the inverse of \$-3/17\$, but we’re looking for the inverse of x, not the reciprocal |
\$(3/17)\$ |
8 |
Choice.C |
This option is incorrect because it is the value of x |
\$- (17/3)\$ |
9 |
Choice.D |
This option doesn’t seem to relate to the correct solution. It doesn’t correspond to the multiplicative inverse of x in the given equation |
\$(-3)/(-7)\$ |
