Answer:
The number of grilled cheese sandwiches sold was 132 and the number of deep fried Twinkies sold was 271
Step-by-step explanation:
Let
x -----> the number of grilled cheese sandwiches
y -----> the number of deep fried Twinkies
we know that
The system of equations that represent this scenario is equal to
x+y=403 ------> equation A
4.85x+2.95y=1,439.65 ------> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
The solution is the point (132,271)
see the attached figure
therefore
The number of grilled cheese sandwiches sold was 132 and the number of deep fried Twinkies sold was 271
B is the answer
Have a nice day

Step-by-step explanation:
Answer:
Using Pedmas rule:
<u>subtract: 6-6 = 0</u>
<u>simplify the following</u>
<u>the numerator and denominator cancels out</u>
Answer: (2 1/2, 0) (the last option)
Step-by-step explanation:
I guess the function is:
f(x) = (2 1/2) - (3 1/2)*x
now, the rule for f-1(x) that we know is:
f-1( f(x) ) = x.
So if we want to find the x-intercept of f-1(x), we must evaluate it in f(0)
f-1(f(0)) = 0.
And we have that f(0) = (2 1/2) - (3 1/3)*x = 2 1/2
This means that the x-intercept of f-1(x) will be when x= 2 1/2, so the intercept is:
(2 1/2, 0)
