Answer:
-4.67
Step-by-step explanation:
first find f^-1(x)
let f(x)=y
y=3x+2
3x=y-2
x=y-2/3
Therefore f^-1(x)=x-2/3
Now f^-1(-12)=-12-2/3
=-14/3
=-4.67
Answer:
x + 2y ≤ 100 and x + 3y ≤ 400
Maximum profit = 6x + 5y.
Step-by-step explanation:
Let there be x number of small dishes and y number of large dishes to maximize the profit.
So, total profit is P = 6x + 5y .......... (1)
Now, the small dish uses 1 cup of sauce and 1 cup of cheese and the large dish uses 2 cups of sauce and 3 cups of cheese.
So, as per given conditions,
x + 2y ≤ 100 ........ (1) and
x + 3y ≤ 400 .......... (2)
Therefore, those are the constraints for the problem. (Answer)
Answer:
Put one point on (0, -4)
Put the other on (3, -2)
Step-by-step explanation:
That's how graphing works
Answer:correction so 1] y = 3x + 7
// Plug this in for variable y in equation [2]
[2] 5x + 2•(3x+7) = 3
[2] 11x = -11
// Solve equation [2] for the variable x
[2] 11x = - 11
[2] x = - 1
// By now we know this much :
x = -1
y = 3x+7
// Use the x value to solve for y
y = 3(-1)+7 = 4
