Answer: C
Step-by-step explanation: In this problem, we're given a function
in the form of a chart and we're asked to find the inverse of the function.
To find the inverse of a function, we simply switch
the x and y values in each point.
In other words, the point (-1, -2) becomes (-2, -1),
the point (0, 3) becomes (3, 0), the point (1, 8) becomes (8, 1),
and the point (2, 13) becomes (13, 2).

All parallelograms are quadrilaterals.
In this type of problem, we would want to use a system of linear equations.
First, we need to find our equations. We know that the two boys traveled 275 km in total, and since x and y count the distance traveled (just in different modes of travel), we can write: x + y = 275.
Next, the problem says that they biked 55 km more than they bussed. So, x = y + 55.
Now that we have two equations to solve for two variables, we can lay them out next to each other:
x + y = 275
x = y + 55
We see that we can substitute x in the first equation with y + 55. This gives us
(y + 55) + y = 275
We solve for y and get y = 110 km by bus. But, we want to know how far they traveled by bike. So, since x = y + 55 and y = 110, we can solve for x by doing 110 + 55 = 165 km by bike.
The answer is 165 kilometers.
Answer:
Given that,
Suppose 2 quarters, 3 dimes, 3 nickels, and 9 pennies are in a box.
One coin is selected at random.
To find the expected value of the money drawn from the box.
we get,
Total number of coins is 2+3+3+9=17
Probability of getting quarter is,
Probability of getting dime is,
Probability of getting nickel is,
Probability of getting penny is,
we know that,
Using this, we get
The expected value of the money drawn from the box is,
