To make a profit, a company’s revenue must be greater than its operating costs. the company’s revenue is modeled by the expression 7.5x – 100, where x represents the number of items sold. the company’s operation costs are modeled by the expression 79.86 + 5.8x. how many items does the company need to sell to make a profit?

the inequality that will determine the number of items that need to be sold to make a profit is .

the solution to the inequality is .

the company must sell at least items to make a profit.

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

the answer is a if my teacher taught me correct

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

answer: the answer to this problem is 2x and 2-x both have x as well as 2

step-by-step explanation: first you have to see what is the closest thing they have similar second you note it example 4x and 4+x they both have x and 4
