You just need your slope formula:
m = (y2 - y1)/(x2 - x1)
(4, 3) and (9, 14)
(x1, y1) and (x2, y2)
m = (14 - 3)/(9 - 4)
m = 11/5
your slope is 11/5
It is the distributivity of the multiplication from the subtraction
8*(d-5)=8*d-8*5=8d-40
Answer:
Given function:
t(s) = 3s + 20
where:
- t(s) = number of palm trees grown
- s = number of seeds planted
Given function:
s(d) = 20d
where:
- s(d) = number of seeds planted per day
- d = number of days
To determine the composite function that represents how many palm trees Carlos can expect to grow over a certain number of days, simply substitute s = 20d into t(s) = 3s + 20:
⇒ t(d) = 3(20d) + 20
⇒ t(d) = 60d + 20
The unit of measurement is <u>how many palm trees</u> Carlos can expect to grow <u>over</u> a certain <u>number of days</u>:
