Answer:
x = 4.5, 4/7
Step-by-step explanation:
To find the roots of a factored equation you need to set the y value at 0, that way you can solve for x. Once you solve for x you get two quantities, which can be graphed. These two quantities are where the x intercepts are.
Answer:
5/6 and 6/7
Step-by-step explanation:
In the top of the fraction its going up by one each time (1,2,3,4 so the 5 and 6 would be the top half of the fraction), and in the bottom half its also going up by one but it started at 2 so its one more than the top half (2,3,4,5, so the 6 and 7 would be the bottom half of the fraction)
Answer:
Use the line plot in question to answer questions 5 and 6. 5
Answer: 19
Step-by-step explanation:
Using the sum of an arithmetic series formula,
Multiplying the second equation by 2 gives us .
Subtracting this from the second equation, we get that .
Substituting this back into the first equation, we get that .
Therefore,
He lost 85 + 120 + 90 or $295 (actually $-295) since they were losses. h
He made 70+35 or $105 (+$105 since he made a profit).
Together -$295 + $105 = -$190
Now this happened over 5 months so lets get the average loss by dividing by 5
$-190 /5 = -$38 so a. his average loss was $38 per month
