A counter example is
f(x)=5x^5+2x^3+3x
g(x)=-5x^5-x^4+x^2-4
Then f(x)+g(x) = -x^4+2x^3+x^2+3x-4 which is a polynomial of degree 4.
So the answer is no. Counter-example is given above.
Its translated upwards by 6 - (-3) = 9 units
third choice is correct
Answer:
Angle A is 46. Angle B is 134
Step-by-step explanation:
If two angles are supplementary, they equal 180 degrees. So in order to find the measure of each angle, you need to find out what x is, by setting both equations equal to 180.
So it would look a little like this:
6x-8+9x+53=180.
Group like terms together
15x+45=180
get x alone by subtracting 45 on both sides
15x=135
and divide by 15 on both sides
x=9
So now we figured out that x = 9. Now plug that number in for both equations to find the angles of both
6(9)-8
54-8
angle A is 46
9(9)+53
81+53
angle B is 134
And you can check your work by seeing if both angles actually add up to 180, by definition being supplementary
134+46.. is 180
So there you have it
