Answer:
x = 3
Step-by-step explanation:
1. Plug 3 into g(x)
3 = -2x + 9
2. Subtract 9 on both sides
-6 = -2x
3. Divide by -2 on both sides to get x by itself
x = 3
I hope this helped :)
Hey, okay, so you just FOIL it.
F - first, O - outside, I - inside, L - last.
multiply x&2x, x&3y, -3y&2x, -3y&3y.
So it should look like this:
2x^2+3xy-6xy-9y
so the final answer should be
2x^2+3xy-9y
Answer:
(-4,1)
Step-by-step explanation:
1. Reflection in the y-axis- if we are only focusing on A then you have to make the x negative:
A (-4,1) A' (4,1)
2. Reflection in the x-axis- make the y negative in the point A:
A' (4,1) A'' (4,-1)
3. Rotate 180 degrees- (x,y) rotated 180 degrees is (-x,-y):
A" (4, -1) A'''(-4, 1)
side note: if 1 is already negative than two negatives make a positive, which is why -1 becomes 1 after the 180 degree rotation
<u>Supplementary:</u> N and M
Supplementary angles: A pair of angles whose sum is equal to 180°.
<u />
<u>Vertical:</u> N and R
Vertical angles: A pair of angles that are made by two intersecting lines.
<u>Complimentary:</u> P and Q
Complimentary angles: A pair of angles whose sum is equal to 90°.
Hope this helps! :D
