It would be B: a set of points that extends infinitely in two directions
Answer:
0 solutions
Step-by-step explanation:
4(x-2)=4x+10
4x-8 = 4x+ 10
-8 = 10 (not true)
(When you have something like 6=7, 0 solutions. If it is like 6=6, infinite solutions. x=6, one solution)
Answer:
9/15 = 3/5 (simplified)
Step-by-step explanation:
In a right triangle, the cosine is the ratio of the adjacent side to the hypotenuse:

The adjacent side is the side that makes up the angle but is not the hypotenuse.
I'm assuming the answer box should ask for cos(theta) rather than cos(x).
Answer:
0.005323
Step-by-step explanation:
Use the algorithm method
F(1) = 8
Steps:
f(x) = 7(x-1) + 8
f(1) = 7(1-1) + 8
f(1) = 7(0) + 8
f(1) = 0 + 8
f(1) = 8
