Rafael is driving to Memphis. Suppose that the distance to his destination (in miles) is a linear function of his total driving time in minutes). Rafael has 52 miles to his destination after 40 minutes of driving, and he has 39.4 miles to his destination after 58 minutes of driving. How many miles will he have to his
destination after 72 minutes of driving?

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
