Answer:
Step-by-step explanation:
<u>Given:</u>
- r(x) = 18x and
- c(x) = 8x+ 30
<u>Find p(x) by substituting the above into the following equation:</u>
- p(x) = r(x) - c(x)
- p(x) = 18x - (8x + 30) = 18x - 8x - 30 = 10x - 30
Correct choice is A
This is simple math, you know 60 minutes in 1 hour, so do 60 x 41 = 2,460
So it spins 2,460 times per hour.
Hope this helps!
Answer:
see explanation
Step-by-step explanation:
(1)
x² - 6 = 2 - 18x ( add 18x to both sides )
x² + 18x - 6 = 2 ( add 6 to both sides )
x² + 18x = 8
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(9)x + 81 = 8 + 81
(x + 9)² = 89
(2)
(x + 9)² = 89 ( take square root of both sides )
x + 9 = ±
( subtract 9 from both sides )
x = - 9 ± 
In total they have $80 so that means Carlos have 35 Jeremy have 25 and Michele have 20 then 20 divide 80 gives u the percentage out of 100 the answer is 25
