It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The equation to represent the cost would be y=46+0.25x

x is the number of miles.

a) What is your cost if you travel 57 miles?

Plug x = 57 in the above equation:

y = 46 + 0.25(57)

y = $60.25

b) If your cost was $65.00, how many miles were you charged for traveling?

Plug y = 65 in the equation:

65 = 46 + 0.25x

x = 76 miles

c) Suppose you have a maximum of $100 to spend for the car rental. What would be the maximum number of miles you could travel?

Plug y = 100 in the equation:

100 = 46 + 0.25x

x = 216 miles

Thus, the answer for part a is $60.25, for part b the answer is 76 miles, and for part c the answer is 216 miles.

What are three different methods for solving systems of equations and when would you use each one?

Marrrta [24]

The first method is substitution. This is when the x or y value that is known is substituted into one of the equations. This should be done when you can easily see or find the x or y value.

Example: x = 3, and x + 8y = 30.

The x was given in the first equation (x = 3), and can therefore be substituted into the other equation to find y.

The next method is elimination. This is when you add the two systems together and eliminate either the x values or the y values. This should be done when there are opposite signs of the same number in both equations.

Example: y - 3x = 24, and 2y + 3x = 7

In the first equation you have -3x, and in the second you have 3x. If you were to add the two equations, the x values would cancel out and you would be left with:

y + 2y = 24 + 7

And then you could solve for y.

The last method is to graph both equations and to see at which point the lines intersect.

8.3 repeating as a fraction

MA_775_DIABLO [31]

8 and 3/10 because the 3 is in the ones place so you make that a fraction which would be 3/10. Then 8 would be a whole number. Hope this helps!
