Answer:
up, down
Step-by-step explanation:
It is an even-degree polynomial. Therefore, the start of domain is the opposite the end of domain.
Meaning if the graph starts by decreasing, the graph will end by increasing.
Because the coefficient of highest degree is in negative. Therefore, the graph starts from negative infinity, increasing. The graph will end in positive infinity but decreasing.
Therefore, the answer is first choice.
Answer:
a(8x+2y) = 8ax+2ay
Step-by-step explanation:
You can use the Pythagorean Theorem since it's indicated in the problem that the triangle is right (has a 90 degree angle in it).
So what you can do is use: a^2 + b^2 = c^2
8^2 + x^2 = 16^2
64 + x^2 = 256
x^2 = 192
x = 8√3
I don't think you can use tangent in this problem since no other interior angles are given.
-3 = -x + 2
-2 -2
-5 = -x
/-1 /-1
5 = x
