20 + 10 − 25 = 5

20 − 10 + 25 = 35

Answer 2

David runs out of gas so he gets out of his car and walks 34 yards north and 47 blocks yards east. How far is he from his car if he walked back in a straight line? Round your answer to the nearest tenth.

Answer 3

[AI-generated answer — Bot GPT 3.5]

To find the distance David is from his car after walking north and east, we can use the Pythagorean theorem.

Let the distance from his car be represented by d. Then,

d^2 = 34^2 + 47^2
d^2 = 1156 + 2209
d^2 = 3365
d = √3365
d ≈ 58.0

Therefore, David is approximately 58.0 yards from his car if he walked back in a straight line.

Answer 4

What is the smallest value of y that would make the following list of points, not a function?

{(___, 14), ( 3,16), ( 13,20)

Answer 5

[AI-generated answer — Bot GPT 3.5]

For a set of points to represent a function, each x-value must be unique.

In this case, we have the points (___, 14), (3, 16), (13, 20)
For the set of points to not be a function, the x-value of the first point would need to be the same as the x-value of one of the other points.
So, the smallest value of y that would make this list of points not a function is y = 3; which would make the x-value of the first point the same as the x-value of the second point.

A series of points in the form (x, y) is a function if every
-value is different.

A graph is a function if a vertical line passes through the graph at most
time.

Answer 7

A series of points in the form (x, y) is a function if every x-value is different. This is known as the vertical line test.

A graph is a function if a vertical line passes through the graph at most one time. This means that for every x-value, there is only one y-value associated with it. This ensures that each x-value is unique, as required for a function.
