Answer:
f(6)
Step-by-step explanation:
f(t) represents the cost for t years after 2000. Then for 2006, t=6 and the cost is ...
f(6)
First we are going to set up two equations:
1)
2)
where x is the number of hotdogs sold, and y is the number of sodas sold. Let's subtract x from the second equation and set equal to 0:
1)
2)
Then let's add the two equations together to cancel out the y variable:
+
---------------------------------
Then solve for x:
So then return to equation 1 and plug in x to solve for y:
So then we know that x = 42 and y = 126; therefore, there were 42 hotdogs sold, and there were 126 sodas sold.
7.15= Seven and fifteen hundredths so .15 is 15/100

Answer:
Equation 2 is non-linear, Equation 1 is linear.
Step-by-step explanation:
A linear equation is an equation with a constant gradient and can be expressed in the form y = mx + c. Hence Equation 1 Satisfies this as it is in that form and has a constant gradient of 4. Equation 2 is not in the form y = mx + c since there is a square and hence its non-linear.
