Step-by-step explanation:

j: m=-4/3 b=5

k: m=2 b=-2

l: m=3 b=0

m: m=-1/3 b=-2

n: m=1/4 b=5

For J, M is equal to -4/3 and b is equal to 5

For K, M equals 2 and be equals -2

For I, M is equal to 3 and b is 0

For M, M is -1 over 3 and b = -2

Lastly for N, M = 1/4 and b is 5

To find the probabilty, we need to divide the number of events by the number of possible outcomes.

Answer:

8 cm cubed

Step-by-step explanation:

Because that the cubes are well, cubes, all the sides are the same. If 1 side= 1, then the other ones are too. Once you look at the prism, you will notice that there are 8 cubes in total. Let's find the volume of 1 cube first:

The formula is:

w*h*l = v

1*1*1=1

The volume for 1 cube is 1 cm cubed.

1*8=8

The volume for the prism is 8 cm cubed.

Answer:

8.5

Step-by-step explanation:

There are 34 squares. Each square is 0.5 cm by 0.5 cm, so each square has an area of 0.25 cm^2.

0.25 x 34 = 8.5.

Answer:

y = 0.45x + 2.85

Step-by-step explanation:

to solve we can first subtract the initial cost by taking the price at 0 miles and subtracting it from one of the higher numbers, we will go with $5.10 at 5 miles for this example

5.10 - 2.85 = 2.25

now we have the price for just the 5 miles separated from the initial cost, but we still need to figure out what each single mile is, so now we just divide by 5, one for each mile

2.25 / 5 = 0.45

so $0.45 is the cost to ride for one mile, and the initial cost is 2.85, now all we have to do is implement those numbers into a formula, since 0.45 is for each mile, it is multiplied by the miles, or x, so that will be put together below

0.45x

then we have the value to add to that, 2.85

0.45x + 2.85

and that is = to y, the cost to ride in a San Francisco taxi

The cost of a taxi in San Francisco is higher compared to New York and the equation of line is y = 0.75x + 2.85

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

y = 0.40x + 2.50   be equation (1)

where y represents the cost of the taxi in New York for x miles driven

Let the first point be P ( 0 , 2.85 )

Let the second point be Q ( 5 , 5.10 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 5.10 - 2.85 ) / ( 5 - 2 )

Slope m = 0.75

And , the equation of line for the cost of the taxi in San Francisco for x miles driven is given by

y - ( 2.85 ) = ( 0.75 ) ( x - 0 )

Adding 2.85 on both sides , we get

y = 0.75x + 2.85   be equation (2)

So , when x = 1 mile

y = $ 3.60

And , when x = 1 in equation (1) , we get

y = $ 2.90

Therefore , the cost of a taxi in San Francisco is higher compared to New York

Hence , the equation of line is y = 0.75x + 2.85 for the cost of taxi in San Francisco
