F(1) = (1)^3 + 2(1)^2 - 5(1) - 6 = 1 + 2 - 5 - 6 = -8; x = 1 is not a solution to the polynomial.
f(-1) = (-1)^3 + 2(-1)^2 - 5(-1) - 6 = -1 + 2 + 5 - 6 = 0; x = -1 is a solution to polynomial.
From the options, a or c has x = -1, both has x = , so lets check for x = 3
f(3) = (3)^3 + 2(3)^2 - 5(3) - 6 = 27 + 18 - 15 - 6 = 24; x = 3 is not a solution to the polynomial.
Therefore the solutions to the polynomial are x = -3, x = -1, x = 2
Well if you take the thing a multiple of your time you need me and I the thing is that you don’t have to go to sleep so you don’t have to go to sleep so you don’t have to go get there are new only fans the
Answer:
use this equation: 150=1x+0.5y
Step-by-step explanation:
a) standard form equation above
b) 150=1x+0.5y
subtract 1x from both sides
then divide all by 0.5 to get slope intercept form
c) plug it in: 150=1(40)+0.5y and solve to get 220
d) take the y intercept from answer b. and the y intercept shows how many you have to sell of each to reach you $150(I think, this part might be wrong...idk)
Minimum possible number of guests is zero.
C = 60 + 15(0) = $60
Maximum possible number of guests is 100.
C = 60 + 15(100) = $1,560
That looks like Choice (d).
