The cost y (in dollars) to rent a lane at the bowling alley is proportional to the number x of hours that you rent the lane. It costs $18 to rent the lane for 2 hours.
a) Write an equation that represents the situation
b) Interpret the slope
c)How much does it cost to rent the lane for 3 hours?

Answers

Answer 1

Answer:

a) y = 9x

b) For every increase of 1 hour the price to rent the lane increases by $9.

c) $27

Step-by-step explanation:

a) Since it costs $18 for 2 hours we can infer that for every 1 hour it costs $9.

So, the equation would look like this:

y = 9x

b) In this context, for every increase of 1 hour the price to rent the lane increases by $9. Like the question gave us, the price for 2 hours cost $18.

c) Plug 3 into the equation:

y = 9(3)

y = 27

Therefore, it costs $27 to rent the lane for 3 hours.

I hope this helps!!

- Kay :)

Answer 2
A) Y=9x
B) m=y/x
M= 18/2
M=9/1

For every a hour you pay 9$ (which btw is bull)

C) 27$

Initial cost x hours or

3(x)=y
3(9)=y
27=y (that’s the same thing as y=27)

What is the equation of a line passing through point (6, -2) and has a y-intercept of 8?

Answers

Answer:

y = -1.667(x) + 8

Step-by-step explanation:

Slope intercept form = (y = mx+b)

X = 6

Y = -2

Y-int = 8

Substitute the values

-2 = m(6) + 8

-10 = m(6)

4.) Write the equation of the line shown below? SHOW WORK!

Answers

Answer: y=1/5x-3/5


Explanation:


Use points (3,0) and (-1,-1) to find the slope and y-intercept.

Use y1-y2/x1-x2 to find slope


-1-0/-1-4
=-1/-5
=1/5

So the slope is 1/5


Then use y-y1=m(x-x1) to find the y-intercept.

y-0=1/5(x-3)

y-0=1/5x-3/5

So the equation is y=1/5x-3/5

Q#1: Amanda and Lisa are playing games at the arcade. Amanda started with $15, and the machine she is playing costs $0.75 per game. Lisa started with $13, and her machine costs $0.50 per game. After how many games will the two girls have the same amount of money remaining?
Q#2:The Lone Star Shipping Company charges $14 plus $2 a pound to ship an overnight package. Discount Shipping Company charges $20 plus $1.50 a pound to ship an overnight package. For what weight is the charge the same for the two companies?

Answers

Let D = the amount of money Deanna has after x games.

We know Deanna started with $15 and she spends 0.75 per game, so we can make the following equation:
D = 15 - 0.75x

Let L = the amount of money Lisa has after x games.

We know Lisa started with $13 and she spends 0.50 per game, so we can make the following equation:
L = 13 - 0.5x

The question is asking how many games need to be played for L and D to be equal, so just equate L and D and solve for x:

D = L
15 - 0.75x = 13 - 0.5x
15 - 13 = -0.5x + 0.75x
2 = 0.25x
2 = (1/4)x
8 = x

Therefore they need to play 8 games each to have the same amount of money.

Answer: For question one its 8

Step-by-step explanation: Let A be the variable for Amanda! The amount of money she has for x amount of time. We know that lisa has $13 and she is spending .50 every game. The equation for this would be L=13-0.5x. SO to solve this problem of when they both will have the same amount of money use the equation. 15- 0.75x=13 - 0.5x then you will switch the equation around. So the next step would look like 15-13= -0.5x + 0.75x! Then you'll get 2=0.25x change that to a fraction and you'll get 1/4 and 8=x!

At a dinner, one meal cost $22 and a sales tax of $1.87 was added to the bill.

Answers

Answer:

5.61; 8.5 %

Step-by-step explanation:

Tax = $1.87 per $22 meal

For a $66 meal,

Tax = 66 × 1.87/22

Tax = 3 × 1.87

Tax = $5.61

=====

Tax rate = 1.87/22 × 100

Tax rate = 0.085 × 100

Tax rate = 8.5 %
