A video store charges $8 to rent a video game. You must be a member to rent from the store, but
the membership fee is free. Another video store in town charges only $3 to rent a video game for a
5 day period, but membership in this store is $50 per year. Which rental plan is more economical?
Explain in detail and give examples.

Answers

Answer:

The $3 per video game with $50 membership is more economically if you rent at least 11 games or more per year

Step-by-step explanation:

there are 365 days in a year

3 x 365 = 1095

1095 + 50 = $1145 (Cost per year)

8 x 365 = $2920 (Free Membership) cost per year

If you only rent 10 video games per year, they equals the same amount

$3 x 10 (games) = $30 Then $30 + $50 (Member Fee) = $80

$8 x 10 (games) = $80 for 10 games rental

If they rent 11 games or more per year, then the $3 rental is more economical.

$3 x 11 = $33; $33 + 50 = $83

$8 x 11 = $88

evaluate f(3) for the function f(x)= 15x^2 -x+20

Answers

Answer:

[tex] \huge \boxed{f(15) = 152 }[/tex]

Step-by-step explanation:

[tex]f(x) = 15 {x}^{2} - x + 20[/tex]

To find f(3) , substitute the value of x that's 3 into f(x). That is for every x in f(x) replace it with 3.

We have

[tex]f(15) = 15( {3})^{2} - 3 + 20 \\ \: \: = 15(9) + 17 \\ = 135 + 17 \: \\ = 152 \: \: \: \: \: \: \: \: \: \: [/tex]

We have the final answer as

[tex]f(15) = 152 [/tex]

Write an equation for the line that passes through the points (1,4) and (2, -4).

Answers

Answer:

-8

Step-by-step explanation:

We can use the formula [ y2-y1/x2-x1 ] to solve.

-4-4/2-1

-8/1

-8

Best of Luck!

First of all, Let's find the slope because we need it on the formula for finding the y-intercept.

m = y2 - y1 / x2 - x1

From the points given in the question,

x1 = 1

x2 = 2

y1 = 4

y2 = -4

Plugging in the above formula,

➝ m = -4 - 4 / 2 - 1

➝ m = -8 / 1

➝ m = -8

Now finding the y-intercept[tex]:[/tex]

➝ y = mx + b

And if we put in the values from our first point (1, 4) we get

➝ 1 = -8 (4) + b

➝ 1 = -32 + b

➝ b = 1 + 32

➝ b = 33

Required equation of the line:

➝ y = -8x + 33

samantha has 20 marbles paul has m marbles. Of samantha has 6 times as many marbles as paul, write an equation to show how many marbles paul has?

Answers

Answer:

20 = 6m or m = 20/6 = 10/3

Step-by-step explanation:

Let's say Samantha has s marbles and Paul has m marbles.

We know that s = 20 and that Samantha has 6 times as many marbles as Paul. This means s = 6m.

Substitute 20 in for s:

20 = 6m

m = 20/6

Thus, the equation is m = 20/6.

Answer:

20 = 6m or m = 20/6 = 10/3

Michael received a grant to make a community garden. He makes a scale drawing of his vision for the garden. Michael's drawing shows the layout of 9 raised garden beds of the same size. The scale from his drawing to the actual garden is 2 cm for every 1 ft. What is the actual area of one of the garden beds? (HINT: the formula is A = L x W. How many things do you need to find?)

Answers

Step-by-step explanation:

Find the diagram to the question attached.

From the diagram, we are given the following dimension for one of the beds;

Length = 16cm

Width = 8cm

If the scale from his drawing to the actual garden is 2 cm for every 1 ft, then on converting to feet;

2cm = 1ft

16cm = x fr

cross multiply

2x = 16

x = 8ft

Hence 16cm = 8ft (based on the scale)

Similarly:

2cm = 1ft

8cm = x fr

cross multiply

2x = 8

x = 4ft

Area of the garden bed (in feet) = Length * Width

Area of the garden bed = 8ft * 4ft

Area of the garden bed = 32ft²

Hence the actual area of one of the garden beds is 32ft². We need to find 2 things fir us to get the required answer. First is the length of the bed in feet and the second is the width of the bed in feet.
