the planets days and nights length depends on its tilt and rotation speed. so it has nothing to do with that. A and C are wrong
the longer it takes to revolve around the sun the longer the year is, so its not B
You always either divide the equation or multiply the equation
hope this helps
The answer is 7.
Look at the x=8 and then look up the y-value.
The graph passes (8,7) so therefore when x = 8 the y is 7
The proposal for the price for a number of shirts given by the four companies can be analyzed graphically, given that each price list gives a straight line, and the result presented using a piecewise function approach as follows:

<h3>What is a piecewise function?</h3>
A piecewise defined function is one that has other sub functions which are applied over different intervals of the domain.
The given table of values and equation are plotted on a graph using MS Excel
From the graph, and the table created, we have:
When the number of shirts on order is less than 40, the least expensive is Easy Calculation shirts
When the number of shirts are more than 40 but less than 80, the least expensive proposal is given by Shirtee
When the number of shirts to be ordered is more than 80, the company that gives the least expensive proposal is T-Shirts R Us
The selection table is presented as follows:
