Answer:
5
Step-by-step explanation:
The equation 
is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format 
, such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,
The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation is given in the slope-intercept form, and the coefficient (
) equals (
), therefore the slope is ().
Answer:
D Over the interval [4, 7], the local minimum is -7.
Step-by-step explanation:
Answer:
24 mph for both 60 miles and 40 miles.
Step-by-step explanation:
We need to find how long it takes to get to college and from it.
Speed x time (x) = Distance (60)
30x = 60
x=2
It takes two hours to get to college
20x = 60
x = 3
It takes 3 hours to get back. It's a total of 5 hours, 2 hours at 30mph and 3 at 20. Now we need to find the average
30+30+20+20+20=120
120/5= 24
The average speed for the round trip is 24.
To do the second part, we follow the same process, but replace 60 with 40 for distance.
30x=40
x= 1.33
20x=40
x=2
We can add the total distance and divide by total time to find the average.
The total distance is 80. Time is 3.33
80/3.33=24
The average speed is still 24.
Answer:
It's a graph, see the image.
Step-by-step explanation:
Use the equation to find the slope. Use the slope and the point to graph the line.
