Black diamond ski resort charges $25 for ski rental and $10 an hour to ski. Bunny hill ski resort charges $50 for ski rentals an
aleksley [76]

Answer:

Five hours at both ski resorts cost the same

Step-by-step explanation:

Let x = hours      Let y = cost

Black Diamonds Ski Resort:  25 + 10x = y

Bunny Hill:  50 + 5x = y

Since the cost should be equal, we can substitute for these two equations.

25 + 10x = 50 + 5x

Solve for x:

x = 5

Check: Plug in for x

Black Diamonds Ski Resort: 25 + 10(5) = 25 + 50 = $75

Bunny Hill: 50 + 5(5) = 50 + 25 = $75

The cost is the same, so we know that five hours has the same cost at both ski resorts.

I hope this is correct! Please mark me as brainliest if this is correct :3

A line has a slope of -5/3 through which two points could this line pass?
lyudmila [28]
The answer would be D. (11,14),(8,18)

To find the answer you need to find an equal slope.

To find the slope you need to do y2-y1/x2-x1

Y2 is 18, y1 is 13, x2 is 8, and x1 is 11

18-13/8-11
5/-3=

In the question, we are given the table of values below.

Using the graph plotter,

The slope(m) and the intercept(c) is given as (nearest tenth)

m=14.0\text{  and c =}478.7

This can be inserted into the equation of best fit below

y=14.0x+478.7

Also, the correlation coefficient is given as

r=1.0

The relationship is also strong and positive
