Answer:
12.7=x
Step-by-step explanation:
y=mx+b
10=.65x+1.75
-1.75 -1.75
<u>8.25=.65x</u>
.65 .65
12.69=x round up
12.7=x
When you take the square root of a plus number, you get 2. It is often written as +/- something.
For example sqrt 64 = +8 and - 8
(8)*(8) = 64
(-8)(-8) = 64 Remember when 2 minus' are multiplied together, you get a plus.
Oddly, when you take the cube root of something, you get only 1 answer. When you take an advanced math course, you will find out that it is three. But until you know what a complex number is, the answer is 1.

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).
