Find the slope determined by the following pair of points:

(1/15,0) (2,1/4)

Answers

Answer 1
Answer:

Answer:

\large\boxed{m=(15)/(116)}

Step-by-step explanation:

The formula of a slope:

m=(y_2-y_1)/(x_2-x_1)

We have two points:

\left((1)/(15),\ 0\right),\ \left(2,\ (1)/(4)\right)

Substitute:

m=((1)/(4)-0)/(2-(1)/(15))=((1)/(4))/((30)/(15)-(1)/(15))=((1)/(4))/((29)/(15))=(1)/(4):(29)/(15)=(1)/(4)\cdot(15)/(29)=(15)/(116)

a company paid $48 for two cases of printer paper. each case contained 12 packages of paper. next month the company's office manager needs to order 180 packages of the same paper .if the price per package does not change what would be the total cost of next month's order?

Answers

Well, if two cases of 12 packages of printer paper cost $48, then 24 packages cost $48. This means that each package cost $0.5. Multiplying this by 180, we get a total of $90 for 180 packages of paper. A is the answer.

You travel between these two mile markers and then find your average speed in miles per hour. Which equation does NOT represent this situation?

Answers

Answer:

The correct option is C.

Step-by-step explanation:

The time in first figure is 3:00 pm and the time in second figure is 4:30 pm.

So total time taken by car is

4:30-3:00=1:30

It means total time taken by car is 1.5 hour.

The distance in first figure is 50 miles and the speed in second figure is 155 miles.

So total distance travelled by car is

155-50=105

It means total distance travelled by car is 105 miles.

The formula of speed is

Speed=(Distance)/(Time)

Speed=\frac{105\text { miles }}{1.5\text{ hours}}

Therefore option B represents the solution. Option B is incorrect.

Multiply both sides by 1.5 hours.

1.5\text{ hours}* Speed=105\text { miles }

Therefore option D represents the solution. Option D is incorrect.

Divide both sides by speed.

1.5\text{ hours}=\frac{105\text { miles }}{Speed}

Therefore option A represents the solution. Option A is incorrect.

Option C can not represent the solution, therefore option C is correct.
The one that does not represent the situation is the equation       speed/105=1.5

Tara is graphing the equation y=1/2x. she has placed point on the origin and uses the slope to find 2 more points. which points does tara plot ont her grph?

Answers

What are the choices ? ? ?

There re an infinite number of points on the graph.
Here is a small sampling:

(2, 1)
(6, 3)
(12, 6)
(16, 8)
(20,10)
(30, 15)
(40, 20)
(50, 25)
(76, 38)
(82, 41)
(102, 51)
(202, 101)
(30000, 15000) .

Also, take any one of those points, make both numbers negative,
and you'll have another point on the graph.
