Answer:
Inequality: 7.5x – 100 > 79.86 + 5.8x
Solution: x>106
The company must sell at least 106 items to make a profit.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Revenue: 7.5x – 100
Costs: 79.86 + 5.8x
To make a profit, a company’s revenue must be greater than its operating costs.
So:
7.5x – 100 > 79.86 + 5.8x
Solving for x (number of items sold)
7.5x-5.8x>79.86+100
1.7x >179.86
x>179.86/1.7
x> 105.8
x>106
The company must sell at least 106 items to make a profit.

Answer:
y - 5 = 5(x - 1)
Step-by-step explanation:
Two points on the graph are (1, 5) and (7, 35). Going from the first to the second, we see x (the 'run') increasing by 6 and y (the 'rise') increasing by 30. Hence the slope of this line is m = rise / run = 30/6, or 5.
Using the point-slope equation, we get
y - 5 = 5(x - 1)
A square root of any number greater than 0 always has two answers, one positive and one negative.
Squareroot (36) = 6 or -6.
Since 6×6=36 and -6×-6=36.
Squareroot (0)= just 0 because there is no negative 0 (:
