1. Ima Thief robs a bank and takes off in a getaway car. Five minutes Polly Srule takes off after Ima. Assign x and y to the variables in this situation and write an expression for the number of minutes Polly
has been driving.
a. How long has Polly been driving when Ima has been driving for 17 minutes?
b. How long has Ima been driving when Polly has been driving 29 minutes?

a. 12 minutes

b. 34 minutes

Step-by-step explanation:

Here, we are told that Ima has driven 5 minutes before Polly started driving

So if Ima has driven for x minutes , polly would have driven for y minutes but the difference between x and y is 5

So mathematically;

x = y + 5

a. 17 = y + 5

y = 17-5 = 12 minutes

b. x = 29 + 5

x = 34 minutes

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
