Answer:
A. (2,5)
because 3×2 is 6, 6-1 is 5
so y=5
Ah, direct variation/proportion.
That is simply a linear equation with a y-intercept of 0.
So... let's solve this.
Simply put, a direct variation multiplies the x-value by a constant to get the y-value.
Let's take the point

on this graph and solve for the constant of proportionality:

We easily solve that and get our answer of

. (B)
Answer:
x = -7/2 or x =1
Step-by-step explanation:
2xx - 5x - 7 = 0
2x(x - 1) + 7(x - 1) = 0
(2x +7) (x -1) = 0
x = -7/2 or x =1
The diameter can be obtained by the formula A = pi*r^2
First, multiply 0.50 * 100 to obtain the area of the ball, then simplify and solve for the radius. Doubling the radius would yield the diameter. This is shown below:
Area of the ball = 0.50 * 100 = 50 in^2
<span>A = pi*r^2
</span>50 = (3.14)*r^2
r = 3.99 = approx. 4
diameter = 2r
Diameter = 8 inches.
Among the choices, the correct answer is C. 8.0 in.
