You need to isolate the "x" in both inequalities

5x + 7 ≤ -3 Subtract 7 on both sides

5x ≤ -10 Divide 5 on both sides

x ≤ -2

3x - 4 ≥ 11 Add 4 on both sides

3x ≥ 15 Divide 3 on both sides

x ≥ 5

This is your simplified inequalities:

5x + 7 ≤ -3 or 3x - 4 ≥ 11 ---------> x ≤ -2 or x ≥ 5 Your answer is A

A bicycle’s wheel has a radius of 32.5 cm. What distance will the bicycle travel if the wheel turns 100,000 times?

Verizon [17]

I've never done this type of problem before so I might be wrong but I think the answer is 20420352.25 cm

I just took the circumference (204.2035225) and multipled 100,000 which seems too simple to be right

Answer:

Yes, because $x(x -4)$ is equivalent to $x^2-4x$

Step-by-step explanation:

$x(x -4)$ and $x^2-4x$

$x(x -4) = x^2 - 4x$

What is the length of side AB of parallelogram ABCD? units 4g - 8 B q+4

Andrews [41]

Answer:

8 units

Step-by-step explanation:

» Concepts

Parallelogram Side Theorem states that the opposite sides of a parallelogram are congruent, meaning they have the same length.

» Application

In this case, we're asked to apply the theorem to find the value of q and then find the length of AB. Thus, we have to set up the equation 4q - 8 = q + 4.

» Solving

Step 1: Subtract q from both sides.

$4q-8-q=q+4-q$
$3q-8=4$

Step 2: Add 8 to both sides.

$3q-8+8=4+8$
$3q=12$

Step 3: Divide both sides by 3.

$3q/3 = 12/3$
$q=4$

Step 4: Plug in the value of q for side AB.

$4(4)-8$
$16-8$
$8$

Therefore, the answer is 8 units.
