Answer:

P'(-8,-1)

?'(-6,-8)

R'(4,3)

Step-by-step explanation:

If you were to reflect the points across the x-axis, then the rule here would be that the x variable would stay the same while the y variable becomes the opposite.

So,

P(-8,1) = P'(-8,-1)

?(-6,8) = ?'(-6,-8)

R(4,-3) = R'(4,3)

Which of the following is equivalent to f(x)?

Fynjy0 [20]

Answer:

D. $x^{-3/2}$

Step-by-step explanation:

Given function:

$f(x) = \frac{1}{x\sqrt{x} }$

Equivalent expression is:

$\frac{1}{x\sqrt{x} } = x^{-1}x^{-1/2} = x^{-1 - 1/2} = x^{-3/2}$

Correct choice is D

Please help me find the equation xx

Lisa [10]

Answer:

(2x-10) +x +(x+10) = 180
x = 45
(2x-10)° = 80°
(x+10)° = 55°
x° = 45°

Step-by-step explanation:

The equation is an expression of the fact that the sum of the angles in a triangle is 180°.

(2x -10)° +x° +(x +10)° = 180°

For the purposes of the answer box, I'd leave off the degree symbol:

(2x -10) +x +(x +10) = 180

This simplifies to ...

4x = 180

x = 45

Then the angles (CW from top) are ...

(2·45 -10) = 80°

(45 +10)° = 55°

(45)° = 45°
