Answer:

1,-1,3,-3

Step-by-step explanation:

your P is the first number or the number with the highest exponent, your Q is the last number or the number with no variables. So you make a list of what multiplies to your P's and what multiplies to your Q's and you divide your P list by Q. So 3 is made by -1,1,-3,3 and -1 is made by -1,1. So dividing that you get your list of -3,-1,1,3

Grayson needs to order some new supplies for the restaurant where he works. The restaurant needs at least 761 forks. There are c

Triss [41]

The restaurant needs at least 761 forks.

There are currently 205 forks

Each set on sale contains 10 forks,

The number of set taht have to buy are x

Number of forks in x set are = 10x

Since, we need at least 761

So 761 should be graeter than equal to the sum of reamining forks and the new forks

i.e. 761 ≥ 10x + 205

Answer : 3. 761 ≥ 10x + 205

Solve the following for the specified variable<br><br> Z=s/2(P+p); for P

lapo4ka [179]

Answer:

$\boxed{\sf P = \frac{2Z}{s} - p}$

Step-by-step explanation:

$\sf Solve \ for \ P: \\ \sf \implies Z = \frac{s}{2} (P + p) \\ \\ \sf Z = \frac{s}{2} (P + p) \ is \ equivalent \ to \ \frac{s}{2} (P + p) = Z: \\ \sf \implies \frac{s}{2} (P + p) = Z \\ \\ \sf Divide \ both \ sides \ by \ \frac{s}{2} : \\ \sf \implies P + p = \frac{2Z}{s} \\ \\ \sf Substrate \ p \ from \ both \ sides: \\ \sf \implies P = \frac{2Z}{s} - p$

Find the midpoint of segment LK with endpoints L(-2, 4) and K(5,3).

fenix001 [56]

Answer: (1.5, 3.5)

Explanation:
Find the slope by using the coordinates for points L and K.

3 - 4 = -1
5 - (-2) = 7
Slope = -1/7

Then you plot your points on the graph.
But you want to half your slope to find the midpoint. So your slope would now be -0.5/3.5.

And when you follow that slope, you will plot down the coordinate (1.5, 3.5), which is the midpoint.

Hope this helped! :3
