Answer:
a) 7x^2 + 5x
Step-by-step explanation:
(9x^2 + 8x) – (2x^2 + 3x)
Distribute the minus sign
(9x^2 + 8x) – 2x^2 - 3x
Line them up vertically
(9x^2 + 8x)
– 2x^2 - 3x
-------------------
7x^2 +5x
We have that
<span>p(t)=-3t^2+18t-4
using a graphing tool, we can see the maximum of the graph
(see the attached figure)
A) </span><span>In what year of operation does Mr. Cash’s business show maximum profit?
</span>
Mr. Cash’s business show maximum profit at year 3 (maximum in the parabole)
<span>B) What is the maximum profit?
23 (hundred of thousand of dollars) = 2.300.000 dollars
</span>c) What time will it be two late?
(This is the time when the graph crosses zero and the profits turn into losses )
5.77 years, or an estimate of about 69 months.
15% = 0.15
tip = 15 * 0.15 = 2.25
5% = 0.05
tax = 15 * 0.15 = 0.75
total = 15 + 0.75 + 2.25 = $18
Answer:
x-15
Step-by-step explanation:
Sorry for the chicken scratch
It says as x approaches negative infinity y approaches negative infinity and as x approaches positive infinity y approaches negative infinity
