Slopes, y-intercepts, (& points)The membership to your local video store is $10 per year and the DVD rental rate is $3.95 per DVD. Right in equation that models the total amount of money you will spend on DVD rentals this year.

Answers

Answer:

y = 3.95(x) + 10

Step-by-step explanation:

The equation of the money spend will expressed as

Total number spend = 3.95 multiply number of DVD rented (x) + 10 membership

Thus equation is y = 3.95(x) + 10

Final answer:

A linear equation modeling the total cost of DVD rentals for a year, given a yearly membership fee and cost per DVD, is y = 3.95x + 10. This equation represents the cost structure, where 'y' is the total cost, 'x' is the number of DVDs rented, 3.95 is the cost per DVD and 10 is the annual membership fee.

Explanation:

This problem is an example of a linear equation, which describes a straight line on a graph. In this case, the line represents the total cost of renting DVDs for a year. The y-intercept represents the fixed part of your cost - the annual membership fee, and the slope represents the variable part of the cost - the price per DVD rental.

The equation that models this situation is y = 3.95x + 10. Here, 'y' represents the total cost, 'x' represents the number of DVDs you rent, 3.95 is the slope (or cost per DVD), and 10 is the y-intercept (or the cost of membership).

In this scenario, for each additional DVD you rent (increase in x), your total cost (y) increases by $3.95 which is the slope of the line. The line crosses the y-axis at $10, which is the fixed membership cost.

The coastline of the United States is 12,383 miles long. Canada's coastline is 113,211 miles longer than the coastline of the United States. How long is the coastline of Canada?

Answers

So this is basically an addition word problem. Let's start with what we know: the United States Coastline is 12,383 miles long and Canda's Coastline is 113,211 miles LONGER. Whenever there is a synonym for "more", that tends to be addition. So add 12,383 to 113,211 in order to get 125,594.

T is to 9 as 7 is to 39

Answers

Answer:

T = 21/13

Step-by-step explanation:

Step 1: Make an expression

T is to 9 as 7 is to 39

$(T)/(9) = (7)/(39)$

Step 2: Cross multiply

$(T)/(9) = (7)/(39)$

39(T) = 7(9)

39t = 63

Step 3: Divide both sides by 39

39T / 39 = 63 / 39

T = 21 / 13

Answer: T = 21/13

What is the constant of proportionality?
0.75
0.8
1.25
1.5

Answers

Yes really simple, y is the bottom 10 15 and 25 well in a graph y is on the top so put y on top of x and divide. SO 10 divided by 8 15 divided by 12 and 25 divided by 20 which all equal 1.25! Now just because I'm only a helping hand doesn't mean I dont know my math! Hope I helped

y=mx
10=m(8)
m=1.25
the constant of proportionality is 1.25
