How are the functions y=x and y=x-3 related? How are their graphs related? (7 pa

quester [9]

Answer:

Each output for the second function $y_2=x-3$ is 3 less than the corresponding output for the first function $y_1=x.$

The graph of the function $y_2=x-3$ is the graph of the function $y_1=x$ translated down 3 units.

Step-by-step explanation:

<u>Given: </u>

Function $y_1=x$

Function $y_2=x-3$

<u>Find: </u>How are the functions related? How are their graphs related?

Substitute $x=y_1$ into the second function:

$y_2=y_1-3$

This means that each output for the second function $y_2=x-3$ is 3 less than the corresponding output for the first function $y_1=x.$

The graph of the function $y_2=x-3$ is the graph of the function $y_1=x$ translated down 3 units.

6 of 30 is the ratio 6 to 30 or 6/30.

6/30 reduces to 1/5

The survey shows that 1/5 of the students attend summer camp.

1/5 of 200 = 1/5 * 200 = 40

a parking meter contains $8.25 in dimes and quarters. after emptying the meter, the worker counts 51 coins. how many quarters an

Marianna [84]

<h3>30 dimes and 21 quarters are present</h3>

<em><u>Solution:</u></em>

Let "d" be the number of dimes

Let "q" be the number of quarters

1 dime = $ 0.10

1 quarter = $ 0.25

The worker counts 51 coins

Therefore,

d + q = 51

d = 51 - q ---------- eqn 1

<em><u>A parking meter contains $8.25 in dimes and quarters</u></em>

Therefore,

0.10d + 0.25q = 8.25 -------- eqn 2

<em><u>Substitute eqn 1 in eqn 2</u></em>

0.10(51 - q) + 0.25q = 8.25

5.1 - 0.10q + 0.25q = 8.25

0.15q = 3.15

Divide both sides by 0.15

Substitute q = 21 in eqn 1

d = 51 - 21

Thus 30 dimes and 21 quarters are present
