Use the graph below to answer the question that follows.
A graph titled 'Remote-Control Car' shows 'Time' in seconds from 0 to 10 on the x-axis and 'Speed' in miles per hour from 0 to 10 on the y-axis. A line segment connects (0, 4) and (3, 2). A second line segment connects (3, 2) to (8, 5). A horizontal line segment connects (8, 5) to the point (10, 5)
Which statement describes the speed of the remote-control car over time?
A. The speed of the car decreases from 4 mi/h to 2 mi/h in the first 3 seconds, increases to 5 mi/h in the next 2 seconds, and then remains at 5 mi/h for the last 5 seconds.
B. The speed of the car increases from 4 mi/h to 2 mi/h in the first 3 seconds, decreases to 5 mi/h in the next 2 seconds, and then remains at 5 mi/h for the last 5 seconds.
C. The speed of the car decreases from 4 mi/h to 2 mi/h in the first 3 seconds, increases to 6 mi/h in the next second, and then remains at 6 mi/h for the last 6 seconds.
D. The speed of the car decreases from 4 mi/h to 2 mi/h in the first 3 seconds, increases to 5 mi/h in the next 5 seconds, and then remains at 5 mi/h for the last 2 seconds.
so the speed starts at 4, decreases to 2, increases to 5 and stays there
so now just look at the graph and the choices to see which choice matches the time intervals on the graph.
D is good
and A is good for #2
Suppose you earn $10 each hour you babysit. Which function describes the relationship between your total earnings (E) and the number of hours you babysit, (h)?
A. E(h) = 10h***
B. E(h) = h + 10
C. E(h) = h – 10
D. h = 10E
we have a winner!
The data in the table illustrate a linear function.
x 0 2 4 6
y –5 –2 1 4
What is the slope of the linear function? Which graph represents the data?
B. 3/2; Four points are graphed on a coordinate plane. A line connects the four points and continues on in both directions.The points graphed on the coordinate plane are (0, -5), (2, -2), (4, 1), and (6, 4).
D. –3/2; Four points are graphed on a coordinate plane. A line connects the four points and continues on in both directions. The graph is the same as D but with a different fraction.
help please
ty
i have a lot more i need help with
😿
slope = (4-1) / (6-4) for example
that is
+ 3/2
ima fail now
i will be leaving to
goodbye
😿
calculate rise / run
60/100 = 0.60
50/100 = 0.50
20/100 = 0.20
0.60 is the most meters up for every meter horizontal
3/5 / 1 = 3/5 = 6/10 = 60/100 = 0.60 indeed so B. (A. is backwards)
