Part A) Y cannot be described as a function of x, because in order to be a function, there can only be one input, the x value, for every output, f(x) or the y value. Since the x value, 16, generates two y values, -2 and 2, this cannot be called a function.
Part B)
<span>f(x) = 25x + 16
f(20)= 25(20) + 16
f(20) = 500 + 16
f(20) = 516
This is the total cost, in dollars, of renting the truck for 20 hours. </span>
1/x=6/21
What you need to do is set it up as a proportion. 1 cup to 6 cups cake mix, x cups to 21 cups cake mix.
21/6 is 3.5
So 3.5 cups of water to 21 cups of cake mix (:
Hope this makes sense!

Answer:
th answer is 7:15 pm
Step-by-step explanation:
basically just count with your hands if you want, start with one finger and say 13 and go up from there, 7th finger is the 19th. Thats my easiest way of doing it. Or you can subtract 24-19 and subtract 12 from the remaining sum
The solid shape is a SPHERE.
And the surface area of a sphere is given as;
Given the radius r, of the circle as 8cm and pie = 3.14;
The area of the sphere is 803.84 square centimeters
But to the nearest tenth, the area of the sphere 803.8 square centimeters
