Answer:
-1/20
Step-by-step explanation:
For a graph like this you should make the gallons of gas on y-axis and the miles driven on the x-axis.
To find slope the formula is (y2-y1)/(x2-x1)
So in this case it is 2-4/40-0
-2/40
This reduces to -1/20
Answer:
A system of linear equations is a system made up of two linear equations. To solve the system of equations, you need to find the exact values of x and y that will solve both equations. One good way to do this is to graph each line and see where they intersect.
Step-by-step explanation:
Answer:
You can calculate for x by
Step-by-step explanation:
7.5 - 2.8 = 4.7

There are four numbers of 3-coin combinations if we can choose from nickels, dimes, quarters, and half-dollars.
<h3>How to solve probability combinations?</h3>
The coins to select from are nickels, dimes, quarters, and half-dollars;
Thus;
Coins (n) = 4
The number of coin to select is:
Coin (r) = 3
The coin combination is then calculated using:
Combination = ⁴C₃
Apply the combination formula, we have;
Combination = 4
Thus, there are four number 3-coin combinations if we can choose from nickels, dimes, quarters, and half-dollars.
