Although this function could be interpreted two different ways due to formatting, the equation below must be the equation you meant (because the other would create an answer that is not listed in the choices).

f(x)=\dfrac{12}{4x+2}

To find f(-1), substitute the x('s) in the equation with -1.

f(-1)=\dfrac{12}{4(-1)+2}

=\dfrac{12}{-4+2}

=\dfrac{12}{-2}

=-6

That's your answer.

Please answer this multiple choice question CORRECTLY for 30 points and brainliest!!
JulijaS [17]

Solve the inequality for x:

5x - 3 ≤ 7x +7

Subtract 7x from each side:

-2x -3 ≤ 7

Add 3 to each side:

-2x ≤ 10

Divide both sides by -2, also when dividing  both sides of an inequality you flip the direction of the inequality sign:

x ≥ -5

The dot will be on -5, because the inequality includes equal to, the dot is solid and is greater than, the arrow will point to the right.

The correct answer is D.
