I just finished the PLATO test and these are the answers
Answer:
$34.5
$5,951.5
Step-by-step explanation:
P(x)=27+x
Quantity (x)=210-5x
Income(y)=price×quantity
=(27+x)(210-5x)
=5670-135x+210-5x^2
y= -5x^2+75x+5670
dy/dx= -10x+75=0
-10x=-75
x=-75/-10
=7.5
x=7.5
Maximum income=27+x
=27+7.5
=$34.5
Total income=(27+x)(210-5x)
=(27+7.5){210-5(7.5)}
=(34.5)(210-37.5)
=(34.5)(172.5)
=$5,951.25
Answer:
The first number (x) = 8
Step-by-step explanation:
Let x = the first number
Let y = the second number
x = 3*y - 4
2x + 3 - 2y = 11 Subtract 3 from both sides
2x - 2y = 11 - 3
2x - 2y = 8 Divide by 2
x - y = 4 Add y to both sides
x = y + 4 Now go back to the very first equation. Substitute for x
y + 4 = 3y - 4 Subtract y from both sides
4 = 3y - y - 4
4 = 2y - 4 Add 4 to both sides
4 + 4 = 2y
8 = 2y Divide by 2
8/2 = y
y = 4
x = 3y - 4
x = 3*4 - 4
x = 12 - 4
x = 8
F(g(x)) = 2(5x+1)-6 = 10x+2-6 = 10x-4
g(f(x)) = 5(2x-6)+1 = 10x-30+1 = 10-29
10x-4>10-29 because from f(g(x)) you subtract less quantity.
The answer to your question is C. I hope that this is the answer that you were looking for and it has helped you.
