5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2

First Collect like terms:
5x x 2y, +3x x 2,and +8xy x 2

16x x 2y -4x x 2 - 4y x 2—> Multiply the numbers:

Multiply the numbers 16 x 2

16 x 2 = 32

Now multiply the numbers 4 x 2

4 x 2 = 8

Now Multiply the numbers 4 x 2 again

4 x 2 = 8

= 32xy - 8x- 8y

Factor 8 from the expression


Final Answer:
8(4xy-x-y)

I’m not really sure about my answer but i hope it helps!
Sorry if its wrong..
Stay Safe guys!

Write the equation of the line passing through the points (−2,3) and (−1,−2) in Slope-Intercept and Point-Slope Form.
Annette [7]
Point slope form is y-3 = -5( x + 2 )

Slope intercept form is y= -5x - 7

If f(7)=22, then f-1(22)=
nignag [31]

Answer:

f^{-1} (22) = 7

Step-by-step explanation:

The inverse function maps the output of the function back to its input

f(7) = 22 means when input is 7 the output is 22

The inverse maps the output 22 back to the input 7 , that is

f^{-1} (22) = 7

A cylindrically shaped space station is rotating about the axis of the cylinder to create artificial gravity. The radius of the
erica [24]

Answer:

8%

Step-by-step explanation:

The maximum change happens when all 500 people moves form outer surface to the station center. When all of them are at the surface, the total moment of inertia is:

I = I_s + 500I_p = 3*10^9 + 500m_pr_p^2=3*10^9 + 500*70*82.5^2=3.24*10^9

When they are at the axis, the total moment of inertia is only the station's, which is 3*10^9

By the law of angular momentum conservation:

I_1\omega_1 = I_2\omega_2

\omega_2/\omega_1 = I_1/I_2 = \frac{3.24*10^9}{3*10^9} = 1.08

So the angular speed changes by 0.08 of itself, or 8%
