Y-x =17
y = -x + 17

substitute this into the second equation

y = 4x + 2
-x + 17 = 4x + 2
0= 5x -15
15/5 = 5x/5
3 = x

Identify the relation that is also a function.

Tasya [4]

Answer:

A is a function; B, C and D are not.

Step-by-step explanation:

In other words: Identify the sole function among these relationships.

A function maps any input onto exactly one output.

If a relationship maps any input onto more than one output, it is not a function.

Thus, we eliminate B, C and D. In B, for example, we have the inputs {1, 2, 3}, where the '1' has two y-values associated with it.

On the other hand, A has the domain {-1, 0, 1, 2}, and all four inputs have exactly one associated output.

A sphere has a diameter of 24 units. What is its volume in cubic units?

DiKsa [7]

Hello!

The equation to find the volume of a sphere you use the equation

$\frac{4}{3} \pi r^{3}$

r is radius which is half the diameter

put in 3.14 for pi and 12 for r

$\frac{4}{3} *3.14* 11^{3}$

This gives us the answer of 7234.56 cubic units

Hope this helps!
