Answer:
A
Step-by-step explanation:
By vertical line test, if you draw any vertical line, except for A, all graph meet at more than two points. So, graph A represents y as a function of x.
Answer:
D
Step-by-step explanation:
For a circle, the equation of the circumference is c = π * 2r (radius). Since in this case, the circumference is 15.3, that means π * 2r = 15.3. I'm going to assume that pi is 3.14 because the four answers aren't particularly close to each other. This means that 2r = approx. 4.872. If you then divide both sides by 2 you get r = approx. 2.436, which is closest to answer D.
4(5)+4(2)=4(5+2)
=4(7)
=28
8(4)-8(2)=8(4-2)
=8(2)
=16

Answer:
if you are finding x,
x = 15
Step-by-step explanation:
2(5x-6) = 3(3x+1)
10x - 12 = 9x + 3
10x = 9x + 15
x = 15
