Answer: C
Step-by-step explanation:
Since y = 0 at x=3pi/2, we know that this is a cosine graph.
So to determine if its -cos or cosine, we can test the pt (0, 1).
Since cos(0)=1 whereas -cos(0)=-1, the answer is y=cos(x).
Answer:
x=17
Step-by-step explanation:
11x-31=8x+20
solve for x
Answer:
the answer is 87
Step-by-step explanation:
Probably the last two, cause there's so many white marbles and there's three red ones so like, you could probably pull a red so that your chance of getting blue in the last answer is higher
Answer:
The solution is (0, 2).
Step-by-step explanation:
Here we have two different equations for y. Equate them to eliminate y. Solve the resulting equation for x:
y = −1/3x + 2 = y = x + 2
Simplifying, we get (-1/3)x = x, and so x must be 0.
Then, using the second equation, we find that y = 0 + 2 = 2.
The solution is (0, 2).
