The function r =f(t) is f(t) = 1 - 8t/3
<h3>How to evaluate the function?</h3>
The function is given as:
3r + 8t = 3
Make r the subject
3r = 3 - 8t
Divide by 3
r = 1 - 8t/3
This means that:
f(t) = 1 - 8t/3
To calculate f(-3), we have:
f(3) = 1 - 8 * 3/3
Evaluate
f(3) = -7
Also, we have:
1 - 8t/3 = 2
Add 2 to both sides
-8t/3 = 3
Solve for t
t = -9/8

<u>Complete question</u>
Consider the relationship 3r+8t=3
Write the relationship as a function r = f(t)
Evalute f(-3)
Solve for f(t) = 2
36 - 72 = -36
0 - 36 = -36
-100 + 64 = -36
-52 + 16 = 36

Answer:
37 1/4 (answer)
Step-by-step explanation:
One way of approaching this problem would be to rewrite each proper fraction as a decimal fraction:
6.75
+7.25
+8.25
+7.25
+7.75
-----------
This comes out to 14 + 15.5 + 7.75, or
29.5 + 7.75, or
36.0 + 1.25, or 37.25. This is the same as 37 1/4 (answer)
