Complimentary just means that they add to be 90, so you take 90 degrees and subtract the angle you already have in order to get the complementary angle

Which expression is equal to (x+2)(−3x2+3x+1)?
padilas [110]
Multiply everything in the second parenthesis by x.

-3x^3 + 3x^2 + x

Multiply everything in the second parenthesis by 2.

-6x^2 + 6x + 2

Combine these two equations together.

-3x^3 + 3x^2 + x - 6x^2 + 6x + 2

Combine like terms.

-3x^3 - 3x^2 + 7x + 2

Hope this helps!

Eight is added to a number and the sum is doubled, the result is -11 less than the number. Find
inna [77]
If you don’t know what a number is, you should substitute it for x and make an equation with the information you have been given. This gives:

(x + 8) x 2 = x - 11

Then, solve:

2x + 16 = x - 11

2x = x -27

x = -27

This can then be checked by using the number in the original text.

-27 + 8 = -19

-19 x 2 = -38

-38 is 11 less than -27.

Hope this helps :)

What is the slope of the graph of x - 2y = 8?<br> A. 0<br> B. 1/2 <br> C. 2<br> D. -1/2
BaLLatris [955]

Answer:

1/2

Step-by-step explanation:

-2y= 8-X

y= -4+X/2

y= X/2-4

recall that: y= mx+c

in the equation y= x/2+C

m=1/2

where m is your slope
