Function 2 has greater rate of change
Step-by-step explanation:
In order to find the rate of change we have to covert the given linear functions in slope-intercept form
<u>Function 1:</u>
<u></u>
<u></u>
Adding 2x on both sides
<u></u>
<u></u>
Dividing both sides by 5
<u></u>
<u></u>
Let m1 be rate of change of function 1:
<u></u>
<u></u>
<u></u>
<u>Function 2:</u>
<u></u>
<u></u>
Adding 6x on both sides
<u></u>
<u></u>
Dividing both sides by 3
<u></u>
<u></u>
Let m2 be the slope of function 2
<u></u>
<u></u>
As we can see that
<u></u>
<u></u>
Function 2 has greater rate of change

If the height of candle after 10 and 26 hours are 25 cm and 17 cm then the height of candle after 21 hours is 19.5 cm.
Given height of candle after 10 hours is 25 cm , height of candle after 26 hours is 17 cm.
We have to find the height of candle after 21 hours.
We have been given two points of linear function (10,25),(26,17).
We have to first form an equation which shows the height of candle after x hours.
let the hours be x and the height be y.
Equation from two points will be as under:
(y-25)=(17-25)/(26-10)* (x-10)
y-25=-8/16 *(x-10)
16(y-25)=-8(x-10)
16y-400=-8x+80
8x+16y=480
Now we have to put x=21 to find the height of candle after 21 years.
8*21+16y=480
168+16y=480
16y=480-168
16y=312
y=312/16
y=19.5
Hence the height of candle after 21 hours is 19.5 cm.
