13y-7y=9<br> Solve for y, write it as a reduced fraction.
raketka [301]

Answer:

3/2 OR 1 1/2

Step-by-step explanation:

Collect like terms, meaning combine both y's. You should have something like this afterwards.

6y = 9

Now that you have that divide the 6 on both sides so Y is by itself!

Your answer is now 3/2.

I think I know this much so far for A (but I could be wrong):
Eduardwww [97]
Part A. You have the correct first and second derivative.

---------------------------------------------------------------------

Part B. You'll need to be more specific. What I would do is show how the quantity (-2x+1)^4 is always nonnegative. This is because x^4 = (x^2)^2 is always nonnegative. So (-2x+1)^4 >= 0. The coefficient -10a is either positive or negative depending on the value of 'a'. If a > 0, then -10a is negative. Making h ' (x) negative. So in this case, h(x) is monotonically decreasing always. On the flip side, if a < 0, then h ' (x) is monotonically increasing as h ' (x) is positive.

-------------------------------------------------------------

Part C. What this is saying is basically "if we change 'a' and/or 'b', then the extrema will NOT change". So is that the case? Let's find out

To find the relative extrema, aka local extrema, we plug in h ' (x) = 0
h  ' (x) = -10a(-2x+1)^4
0 = -10a(-2x+1)^4
so either
-10a = 0 or (-2x+1)^4 = 0
The first part is all we care about. Solving for 'a' gets us a = 0. 
But there's a problem. It's clearly stated that 'a' is nonzero. So in any other case, the value of 'a' doesn't lead to altering the path in terms of finding the extrema. We'll focus on solving (-2x+1)^4 = 0 for x. Also, the parameter b is nowhere to be found in h ' (x) so that's out as well.

P is the midpoint of HR. Given HP = 7x + 2 and PR = 58; find the value of x
Zielflug [23.3K]

Answer:

x = 8

Step-by-step explanation:

Since P is at the midpoint of HR, then

HP = PR ← substitute values

7x + 2 = 58 ( subtract 2 from both sides )

7x = 56 ( divide both sides by 7 )

x = 8

A cell phone store sold 450 newly released cell phones in three hours. This was 30% of the number of cell phones sold that day.
Vitek1552 [10]

Answer:

we have 3 things here. 30% out of 100% of the 450 phones

In order to find the missing percent we multiply the 450 by 100 and divide its product by 30

The answer is 1500
