Write an equation for the linear function and use it to answer the given question. 9) Normaltown High School's pool record for the 100-yard freestyle was 47.8 in 1990. Assume that
the record falls at a constant rate of 0.03 second per year. What does the model predict for the
record in 2010?
A) R = 47.8 -0.03t; 47.20 seconds
B) R = 47.8t + 0.03;956.03 seconds
C) R = 47.8t - 0.03; 955.97 seconds
D) R = 47.8 +0.03t; 48.40 seconds

it should be a and d. lmk if i'm wrong xd

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

yes

can you rephrase the question ? it is unclear : -)
