Answer:
Reason 1 ) Subtraction Property of Equality
Reason 2 ) Substitution Property of Equality
Statement 3 ) 9x - 54 = 34
Reason 4 ) Addition Property of Equality
Reason 5 ) Division Property of Equality
Step-by-step explanation:
The given equation is -3x²+240x-800
The maximum of the function is given when
where a and b are the constant of a quadratic form ax²+bx+c
We then have
a = -3
b = 240
Substitute these values into the maximum/minimum formula we have
Which means that the maximum profit is obtained when the number of refrigerators produced is 40 items a day
The maximum profit is
p = -3(40)²+240(40)-800 = $4000
Answer:
C.
Step-by-step explanation:
(f+g)(x) ➡ f(x) + g(x)
x/2 - 2 + 2x^2 + x - 3 = 2x^2 + 3x/2 -5
