Marcie solved the following inequality and her work is shown below:. . −2(x − 5) − 12 ≤ 4 + 6(x + 3). −2x + 10 − 12 ≤ 4 + 6x + 1

BartSMP [9]

All steps that Marcie did are right, but she forgot to change sign in last step.

Consider the inequality

$-2(x - 5) -12 \le 4 + 6(x + 3).$

Then

$-2x+10-12 \le 4 + 6x+18.$

Group the numbers:

$-2x-2 \le 6x+22.$

Separate terms with x and without x in different sides:

$-2x-6x \le 22+2.\\-8x\le 24.$

The coefficient at x is -8 and it is negative, then dividing the inequality by -8 you have to change sign in opposite:

$x\ge -3.$

Answer: Marcie forgot to change sign in last step.

What is the inverse function of f(x)= 4- x/6

Westkost [7]

Answer:

$f^{-1}(x) = 6(4-x) = 24-6x$

Step-by-step explanation:

Let $y=f(x)$ and swap x and y:

$x = 4 - \frac{y}{6}$

Then, rearranging for y:

$x+\frac{y}{6} = 4$

$\frac{y}{6}= 4-x$

$y= 6(4-x) = 24-6x$
