Answer:
The problem implies that we want to write the (average) amount of natural sweeteners consumed per person as a function of time. Let y represent the (average) amount of natural sweeteners consumed per person (in pounds), and let x represent the time measured in years since 1990. That is, x = 0 represents 1990. If y is a linear function of x, then we can use the slope-intercept form y = mx + b (where m is the slope and b is the y-intercept) to write the function.
The slope can be interpreted as the rate of change of y with respect to x, which in this case means the change in consumption of natural sweeteners per year. The statement that consumption has decreased by 0.6 pounds per year tells us that the slope is m = -0.6 Also, the y-intercept is the same as the y-value of the function when x = 0. (In our case, that means time 0, that is, 1990.) Therefore the y-intercept is b = 133. Hope that helps! Let me know if you have any further questions.
Step-by-step explanation:
Answer: "possible" rational roots: ±1/5, ±3, ±1
Step-by-step explanation: Take plus or minus the factors of the constant divided by the factors of the leading coefficient.
In this case, the constant is 3, so the factors are 1 and 3, and the leading coefficient is 5, so the factors are 5 and 1.
1/5, 3/5, 1/1 and 3/1 are possibilities, simplify and attach the ± to each.
Answer:
The answer is -20.6
Step-by-step explanation:
-5x-25=78
-5x+25-25=78+25
-5x=103
-5x/-5=103/-5
x=-20.6
