P=-2Q-30 is the answer

Hello there!

-q = 1/2p + 15
Solve for P
-2pq = 30p + 1
-2pq - 30p= 1
Factor out the variable P
p(-2q - 30)=1
Now we can divide both sides by -2q-30
p(-2q - 30)/-2q - 30 = 1/-2q - 30
P = -1/(2q+30)

I hope I helped!

Which expression is equivalent to 7x , if b > 0?
AlladinOne [14]
<h3>Answer:  Choice C</h3>

Work Shown:

7x^2*\sqrt{2x^4}*6\sqrt{2x^{12}}\\\\7*6x^2*\sqrt{2x^4*2x^{12}}\\\\42x^2*\sqrt{4x^{4+12}}\\\\42x^2*\sqrt{4x^{16}}\\\\42x^2*\sqrt{(2x^8)^2}\\\\42x^2*(2x^8)\\\\42*2x^{2+8}\\\\84x^{10}\\\\

So that's why the answer is choice C

The requirement that x is nonzero isn't technically necessary. The original expression simplifies to choice C even when x = 0 is the case. Also, we don't have issues such as division by zero errors that could arise. It's a bit curious why your teacher put in that condition.

What is the solution of the inequality -6x-17≥8x+25
Aleksandr-060686 [28]
-6x -17> 8x + 25.
Get x on one side; Subtract 8x from both sides.
-14x -17 > 25.
Add 17 to both sides to get x by itself.
-14x>42.
Divide both sides by -14 (remember to flip the inequality when dividing by negatives).
x <_ 3 is your solution (line under the inequality).
I hope this helps!
