We can model the equation:y = m x + b, where y is the total profit and x is the number of hotdogs sold.The system of equations is:
90 = 40 m + b210 = 80 m + b---------------------b = 90 - 40 m210 = 80 m + 90 - 40 m210 - 90 = 40 m120 = 40 mm = 120 : 40m = 3b = 90 - 40*3b = 90 - 120b = - 30Answer: The equation is y = 3 x - 30
Answer:
(f+g)(x) > 3 for all values of x
Answer:
Step-by-step explanation:
- x² - 16 = 0
- x² = 16
- x = √16
- x = ± 4
Population: All high school students. We're interested in the health of <em>all</em> of them, that's our population.
Sample: Athletes who were surveyed. Our sample is where we got our actual data.
X^2 - 3x + 5
2^2 - 3(2) + 5
4 - 6 + 5
