A familiar situation is: cost of books you pay for versus the quantity of books bought.

Cost of books ($) and quantity of books are directly proportionally related in the situation.

The graph will look like the graph in the attachment below.

A quantity (dependent variable) will change constantly in relation to another quantity (independent variable) if the relation is a proportional relationship.

A familiar situation for example can be the cost you pay for books will be directly proportional or dependent on the number of books you bought.

That is:

Number of books = independent variable

Cost ($) = dependent variable

A change in the number of books will cause a change in the cost you will pay for buying books.

This shows a direct proportional relationship between the two quantities.

On a straight line graph, the graph will be a proportional graph showing number of books on the x-axis against cost ($) you pay on the y-axis.

Therefore:

A familiar situation is: cost of books you pay for versus the quantity of books bought.

Cost of books ($) and quantity of books are directly proportionally related in the situation.

The graph will look like the graph in the attachment below.

The polynomial −2x2 + 700x represents the budget surplus of the town of Alphaville. Betaville's surplus is represented by x2 − 4

matrenka [14]

Answer:

- x²+ 300x + 50,000

Step-by-step explanation:

The polynomial −2x² + 700x represents the budget surplus of the town of Alphaville.

Again, Betaville's surplus is represented by x² − 400x + 50,000.

{where x is the tax revenue in thousands from both towns}

Now, the expression that represents the total surplus of both towns together will be

= (−2x² + 700x) + (x² − 400x + 50,000)

= - x²+ 300x + 50,000

where x is the tax revenue in thousands from both towns. (Answer)

Hi!

So do 91/7 = 13

which means Frances can do 13 oil changes in 1 day

To find how many he can do in 11 days, multiply 13 and 11

11*13 = 143

Frances can do 143 oil changes in 11 days.

Hope this helps!

a spinner is divied into 8 equal sections,and each section contains a number from 1 to 8.what is the probabilaty of the spinner

mixas84 [53]

Well since there are eight sections of 1-8 that meanst there are 8 different number 5s, and since there are eight sections of 8 it becomes 64, so if my math is correct 8/64ths of the time or 1/8. It might be wrong but I tried.

Bill has $2.00 in quarters and dimes. the number of quarters is 4 less than twice the number of dimes. find the number of coins

Dafna1 [17]

Define your variables:
Q: number of quarters
D: number of dimes

Next, create your equations
Q = 2D-4
25Q+10D=200

Because one variable (Q) is already written in terms of the other variable, D, you can already start solving with substitution.
25(2D-4)+10D=200
50D-100+10D=200
60D=300
D=5

Substitute D back into the other equation to find Q.
Q=2D-4
Q=2(5)-4
Q=6

Substitute D and Q into the second equation to check.
25Q+10D=200
25(6)+10(5)=200
150+50=200

This works, so the answer is right! Bill has 6 quarters and 5 dimes.
