A. The function must be non-linear because he constantly changes his speed and pauses at some places. For it to be linear he would have to be going at a constant rate the entire time.
B. Plot the point (20, 1.2), draw a line from (0,0) to it. Then plot (30, 1.2), because he stays there for 10 minutes. Now plot the point (60, 2.5) because it takes him 30 minutes to walk 1.3 miles to the park. Then plot the point (75, 2.5) because he stays there for 15 minutes. Lastly, plot the point (120, 5) for his return home. Be sure to connect these points together with lines.
So you subtitute into the equation
so T=RH
if R=10 and H=35
so 10 per hour so
10 times 35 or (R times H)
so 350=T
b.
if is R=12 and H=40
subsitute and get
12 times 40 (RH) which is
480=T
Answer:
$42 - 19 = 23 - 15 = $8
Step-by-step explanation:

<u><em>Answer:</em></u>d = 25
<u><em>Explanation:</em></u>To get the value of d, we will need to isolate the d on one side of the equation.
<u>This can be done as follows:</u>
</span>

<span>
<u>First, we will do cross multiplication as follows:</u>
40*15 = 24*d
600 = 24d
<u>Then, we will isolate the d as follows:</u>
24d = 600
</span>

<span>
d = 25
Hope this helps :)</span>
