Problem 1: Plug in the given value into the function and evaluate.

f(x)=|3x|\\f(2)=|3(2)|\\f(2)=|6|\\f(2)=6

Problem 2: Solve the equation for y.

-7x+2y=8

add 7x to both sides to move it to the right side of the equation.

2y=7x+8

Divide both sides of the equation by 2 to get a single y variable on the left hand side.

\frac{2y}{2} =\frac{7x}{2} +\frac{8}{2} \\y=\frac{7}{2}x+4

Simplify the terms to get the the equation into slope-intercept form.

The slope of the line is \frac{7}{2}

I'm a unsure what Problem 3 is asking for sorry I hope the rest is helpful.

Solve the inequality.
maw [93]

The solution to inequality is less than the negative of 21. Then the correct option is C.

<h3>What is inequality?</h3>

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given below.

−(1/3)x + 10 > 17

Then the solution to the inequality will be

−(1/3)x + 10 > 17

       −(1/3)x > 17− 10

        −(1/3)x > 7

When the sign is changed then the equality sign also changed.

(1/3)x < −7

     x < − 21

The value of x is less than the negative of 21.

Thus, the correct option is C.

More about the inequality link is given below.
