Answer:

line y = x
(4, -2), (2, 0), (-2, 3)

Step-by-step explanation:

The graph of an inverse relation is the reflection of the graph of the relation over the line y = x. That interchanges the coordinates of the points of the function. (-2, 4) becomes (4, -2) when so reflected, for example.

Find the unit rate.kilometer in17hourEnter the correct answer in the box.

Nuetrik [128]

The question asks for the unit rate when 1/4 of a kilometer is covered in 1/3 of an hour.

Recall that rate is the quotient of two quantities. In our case the numerator is the distance (1/4) of a kilometer, and the denominator is the time: 1/3 of an hour.

So, we perform the following division of fractions:

1/4 diided by 1/3 which is the same as: 1/4 times 3/1 = 3/4

and since we are asked for the UNIT rate, we do the actual division:

The unit rate is 0.75 km per hour.

How many ways are there to choose a committee of 7 people from a group of 10 people?7201208405040?

lyudmila [28]

Answer: 120

---------------------------------------------------------------------------------------

Explanation:

We have seven slots to fill. Let's call the slots A, B, C, D, E, F, G

There are 10 choices for slot A

There are 9 choices for slot B

There are 8 choices for slot C

There are 7 choices for slot D

There are 6 choices for slot E

There are 5 choices for slot F

There are 4 choices for slot G

We count down because each previous slot reduces the pool to choose from. Multiply those values out: 10*9*8*7*6*5*4 = 604800

Now divide that result by 5040. Why 5040? Because this is the number of ways to arrange 7 people within a single grouping. Note how 7! = 7*6*5*4*3*2*1 = 5040. W're dividing because order does not matter for any committee.

So we have 604800/5040 = 120 which is the answer we want

---------------

Side note: We could use the alternate route of the nCr combination formula

nCr = (n!)/(r!*(n-r)!)

where n = 10 and r = 7
