Answer:

The answer is (-8,-5)

Step-by-step explanation:

Since the midpoint is (2, -5), the 2 endpoints should be equidistant from each other. Since the endpoint that is given (12, -5), is 10 points to the right of the midpoint, the second midpoint should be 10 points to the left of it. 2-10=-8

Therefore, the other midpoint is (-8,-5)

CAN SOMEONE PLEASE SOLVE THIS??????????? NEED HELP!!!!!!!!!!

Hitman42 [59]

Answer:

4. 94 degrees

5. 60 degrees

Step-by-step explanation:

4. This is a pentagon. By definition, all the angles should add up to 540 degrees. So, we can just add up all those expressions and solve for x:

(4x + 2) + 132 + (4x - 10) + (5x - 11) + 128 = 540

Combine like terms:

13x + 241 = 540

Solve for x:

13x = 299

x = 23

Now put this into the expression for angle P:

P = 4x + 2 = 4 * 23 + 2 = 92 + 2 = 94

Thus, P is 94 degrees.

5. Since angles 1, 2, and 3 are equal, then their supplementary angles are also equal. Say that each supplementary angle is x.

We also see that angle 4 = angle 3 + 10. We already set the supplementary of angle 3 as x, so that means that angle 3 = 180 - x (by definition of supplementary angles). This means that angle 4 = 180 - x + 10 = 190 - x. Angle 4's supplementary angle is the one inside the hexagon, and it will be: 180 - (190 - x) = x - 10.

Since angles 4 and 5 are equal, then their supplementary angles are equal, as well. So, the supplementary angle of angle 5 is x - 10.

Finally, we see that the last angle left to figure out in the hexagon is the one with the square. That is 90 degrees (by definition).

The sum of the angles in a hexagon, by definition, is 720. So, let's write all these expressions and set them equal to 720:

x + x + x + (x - 10) + (x - 10) + 90 = 720

Combine like terms:

5x + 70 = 720

Solve for x:

5x = 650

x = 130

The supplementary angle of angle 5 is x - 10 = 130 - 10 = 120. So, the measure of angle 5 is 180 - 120 = 60.

Hope this helps!

Rewrite the following expression with rational exponents. 3 sq root -27x^2 y^7<br> Show your work

andrew-mc [135]

Answer:

Step-by-step explanation:

The square root is possible only if y≤0

if y>0 the expression lose meaning, in fact (-)(+)(+) = (-) and a square root of a negative number doesn’t exist. x^2 is a square so it is ever positive if x is not 0

if y≤0 can be rewritten as:

3(-27x^2y^7)^1/2

or if we want simplify the expression:

$3 \sqrt{3^2 * (-3) * x^2 * y^6 * y} = 3^2|x||y|^3 (-3y)$ ^1/2

we have to put the symbol of absolute value between x and y because a x^2 and y^6 are numbers that are ever positive, while x and y^3 can be also negative. Thanks to the simbol of absolute value we can “force” them to be positive

Andrew is working for his mother's company this summer. He gets paid $0.31 for every 4 words he types. If he wants to earn $175

mestny [16]

Answer:

2,258

Step-by-step explanation:

4 words = $0.31

$\frac{4}{0.31}$ = $\frac{x}{175}$

cross multiple and solve for x

0.31x = (175)(4)

x = about 2,258
