If f(x) = 3x – 2 and g(x) = 6 – 4x, find f(x) + g(x).
Answers
f(x) = 3x - 2, g(x) = 6 - 4x
f(x) + g(x) = (3x - 2) + (6 - 4x)
= 3x - 2 + 6 - 4x combine like terms
= (3x - 4x) + (-2 + 6)
= -x + 4

Answer:
sqrt(2)
Step-by-step explanation:
1. Find the mean.
Mean=1+2+3+4+5=15/5=3
2. Subtract each number by the mean and square the value.
1-3=-2^2=4
2-3=-1^2=1
3-3=0^2=0
4-3=1^2=1
5-3=2^2=4
3. Add the values in step 2 then divide by amount of numbers.
4+1+0+1+4=10/5=2
4.Square the value in step 3 and that is the answer.

Answers
Answer:
(9x² + 8x) - (2x² + 3x)
= 7x² + 5x
Step-by-step explanation:
(9x² + 8x) - (2x² + 3x)
open the bracket
= 9x² + 8x - 2x² - 3x
collect like terms
= 9x² - 2x² + 8x - 3x
= 7x² + 5x
9x^2+8x-2x^2-3x
7x^2+5x

let x= the number of bottles the customers buys
first, lets consider how many bottles the customer must buy for the price to be the same no matter which company.
4x+10=3x+25
.
.
.
x=15, so at 15 bottles, the cost is the same for either company. At this point you look at x=16, one bottle higher, to compare costs, seeing that for company A this is $74 while for company B this is $73, so at 16 bottles company B is cheaper
