Answer:
parabola
Step-by-step explanation:
This is the equation of a parabola, notice that only one of the variables (in this case the variable y) appears squared in the equation, and it satisfies the general form of a parabola with branches pointing horizontally.
Answer:
2 1/3 minutes
Step-by-step explanation:
4/3 minute = 80 seconds
80/4 (from 4/7) =
20 seconds per 1/7
20 * 7 = 140
140 to minutes = 2minutes and 20 sec or 2 1/3 minutes
Answer:
independent variable = number of laps;
dependent variable = number of dollars
Step-by-step explanation:
If we were to put this information into a slope-intercept form equation, the equation would be: y = 5x (dollars raised = 5 dollars per lap walked). In this case, we are going to use the variables l and d instead of x and y, respectively. The equation instead of being y = 5x, it is going to be d = 5l. In the slope-intercept form X will always be the independent variable and y the dependent variable, because the number we get for Y totally depends on what you plugged in for X. In this equation, l is the independent variable (the number of laps she walks) and d is the dependent variable (number of dollars).
