She cooked 25 cookies because 5/6 =25/30 because you multiply each number by 5 and it becomes 25/30. Hope this helped
Answer: 10 and -4
Step-by-step explanation:
3x - 2 Plug in 4 for x
3(4) - 2 = 12 - 2 = 10
5x + 6. Plug in -2 for x
5(-2) + 6 = -10 + 6 = -4
Answer:
x^4-3x^3+x^2-4
Step-by-step explanation:
Given the following functions
R(x) = 2x^4 – 3x^3 + 2x – 1 and
C(x) = x^4 – x^2 + 2x + 3
We are to find the profit function P(x)
P(x) = R(x) - C(x)
P(x) = 2x^4 – 3x^3 + 2x – 1 - ( x^4 – x^2 + 2x + 3)
P(x) = 2x^4 – 3x^3 + 2x – 1 - x^4 + x^2 - 2x - 3
Collect the like terms
P(x) = 2x^4-x^4-3x^3+x^2+2x-2x-1-3
P(x) = x^4-3x^3+x^2+0-4
P(x) = x^4-3x^3+x^2-4
Hence the required profit function P(x) is x^4-3x^3+x^2-4
