Answer:
Y= 0
Step-by-step explanation:
Because y=4 it would be a straight horizontal line so the other line would have to be horizontal
X = Sales Tax Rate
350 * X = 22.75
22.75 / 350 = 0.065
0.065 = 6.5%
Let's consider the first number to be and the second number to be . Based on the information in the problem, we can create the following equations:
Now, we can solve the equations through systems of equations. One way of doing this is by multiplying one of the equations so that there is a term in both equations which can be removed by addition or subtraction. In our case, we can multiply the entire first equation by 2 to get:
Now, subtract from both equations to get:
Now that we have found , "plug" it back into an equation to find :
Our answers are s = -4 and f = 9.
I think it is the first one but I might be wrong
