Answer:
rate=1.28571428571.. (1.29) miles per minute, or 77.1428571429.. (77.14) mph
Step-by-step explanation:
<em>"use distance = rate time (d=rt) to find the number of miles per hour Etty must drive to go 45 miles in 35 minutes. ( remember time is written in hours?"</em>
distance=rate*time--- we know distance and time
45 mi= rate*35
rate=45/35
rate=1.28571428571 miles per minute, or 77.1428571429 mph
Answer:
A. Plant 1 is growing at a faster rate than Plant 2.
Step-by-step explanation:
The slope (m) or rate of growth in Plant 1 is;
m = Change in y ÷ change in x
m = 
= 2
The linear equation of growth in Plant 1 is;
= 2
y = 2x + 1.5
The equation of growth in Plant 2 is; y = 1.5x + 3 (slope of 1.5)
Since the slope in growth of Plant 1 is greater than that in Plant 2, it implies then that Plant 1 is growing at a faster rate than Plant 2.
Answer:
1/2 = r
Step-by-step explanation:
7r + 21 = 49r
Subtract 7r from each side
7r-7r + 21 = 49r-7r
21 = 42r
Divide each side by 2
21/42 = 42r/42
1/2 = r
The correct answer is 19,200. Hope this helps. :)
Step-by-step explanation:
We find the equation of the solid blue line:
The line decreases by 1 unit for every 3 units across.
=> Slope of line = -1/3.
Also the y-intercept is 1.
=> Line equation: y = -1/3 x + 1.
We see that the graph below this line is shaded.
Therefore all y-values below or on the line are represented by the graph.
=> y <= -1/3 x + 1.
The answer is y <= -1/3 x + 1.
