2. Determine if either of the following equations are functions? Draw the graphs and explain how

Mathematics

nekit [7.7K]3 years ago

Answer:

Both equation represent functions

Step-by-step explanation:

The function is the relation that for each input, there is only one output.

A. Consider the equation

y=-\dfrac{3}{5}x+2

This equation represents the function, because for each input value x, there is exactly one output value y.

To check whether the equation represents a function, you can use vertical line test. If all vertical lines intersect the graph of the function in one point, then the equation represents the function.

When you intersect the graph of the function y=-\dfrac{3}{5}x+2 with vertical lines, there will be only one point of intersection (see blue graph in attached diagram). So this equation represents the function.

B. Consider the equation

y=x-x^2

This equation represents the function, because for each input value x, there is exactly one output value y.

When you intersect the graph of the function y=x-x^2 with vertical lines, there will be only one point of intersection (see green graph in attached diagram). So this equation represents the function.

Since the communative property shows you can add or multipy in any order, this means you can add all three of these in a different order and still get the same answer.....For example, you can do $1.25 + $0.80 + $2.75 or you can switch it around and do it in another way

How much dirt is in a hole 5 feet wide, 2 feet long, and 3 feet deep?
Veseljchak [2.6K]

Answer:

30 ft of dirt.

Step-by-step explanation:

We want to know the volume, or the capacity, of the hole.

The formula for volume is to multiply the length, width, and height.

l x w x h

2 x 5 x 3 = 30

So there is 30 ft of dirt in the hole.

plz mark brainliest if this helped :)
