Answer:

PR = 82

Step-by-step explanation:

Since Q is the midpoint of PR, then

PQ = QR, that is

6x - 7 = 5x + 1 ( subtract 5x from both sides )

x - 7 = 1 ( add 7 to both sides )

x = 8

Thus

PR = PQ + QR = 6x - 7 + 5x + 1 = 11x - 6

Hence

PR = 11(8) - 6 = 88 - 6 = 82

Answer:

$B=\dfrac{T+9}{A}$

Step-by-step explanation:

Add 9 to both sides of the equation, and divide by the coefficient of B.

T = BA -9

T +9 = BA

(T +9)/A = B

We can rewrite that with B on the left:

B = (T +9)/A

What is the solution to the inequality x(x - 3) > 0?

Nimfa-mama [501]

Answer:

D) x<0 or x>3

Step-by-step explanation:

x(x-3)>0

either x>0 and x-3>0 .... positive-positive=positive so x>3

or x<0 and x-3<0 ..... negative-negative=positive so x<0

if x=0 then x(x-3)=0

$x^{2}$ Answer:

(Explanation)

Step-by-step explanation:

Part A:

The graph of y = $x^{2}$ + 2 will be translated 2 units up from the graph of y = $x^{2}$ .

If you plug in 0 for x, you get a y-value of 2. The 2 is also not included with the $x^{2}$ , which is why it doesn't translate left.

This is what graph A should look like:

Part B:

The graph of y = $x^{2}$ - 2 will be translated 2 units down from the graph of y = $x^{2}$ .

If you plug in 0 for x, you get a y-value of -2. The 2 is also not included with the $x^{2}$ , which is why it doesn't translate right.

This is what graph B should look like:

Part C:

The graph of y = 2 $x^{2}$ is a stretched version of the graph y = $x^{2}$ . Numbers that are greater than 1 stretch and open up and numbers less than -1 stretch and open down.

This is what graph C should look like:

Part D:

The graph of y = $\frac{1}{2}x^{2}$ is a compressed version of the graph y = $x^{2}$ . Numbers that are in-between 0 and 1, and -1 and 0 are compressed.

This is what graph D should look like:

Two trucks leave a warehouse at the same time. one travels due west at an average speed of 49 miles per hour, and the other trav

Gre4nikov [31]

Well there can be two different solutions for this but i will choose the easier one. Obviously one requires a system of equations which obviously will involve a lot of thinking and some good algebra solving in order for them to solve.

So we can just keep adding the distance as we know they are in different directions. 49 + 65 = 114. So 114 * 4.5 = 513 miles. SO after around 4.5 hours they will be 513 miles apart.
