PLEASE HELP!! Stuart invested $800 in a computer and now makes $5 a page typing research papers. Let x represent the number of pages Stuart has typed, and let y
represent his profit.

a. Write an equation for y in terms of x.

y = 5x - 800

Step-by-step explanation:

If x represents the number of pages typed, 5x will represent how much money he earns from typing them, since he gets $5 per page.

Then, 800 needs to be subtracted from this because he spent $800 on the computer.

So, the equation will be y = 5x - 800 to represent his profit.

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
