The first equation is 1x + 1y = 8, satisfied by all four answers.
The second equation is 2x+3y =36; checking we find
2(-12)+3(20) = -24+60 = 36
Choice C
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>:
