Step-by-step explanation:
7y + 4x - 10 + 5y - 5 + x
= 7y+5y+4x+x–10–5
= 12y+5x–15
The constant is 3.
This is because when x=1, y=3 and when x=2, y=6 so that is a constant change over each interval as seen in the graph which is 3 :)
The Time taken by Jacob to run the dash race is (80 - t) seconds
<h3>How to write algebraic expressions?</h3>
We are told that;
Total distance for the dash race = 500 yards
Time taken by Jacob to run the dash race = 80 seconds
Now, we are told that Juan ran the same dash race but used t less seconds than Jacob. Thus;
Time taken by Jacob to run the dash race = (80 - t) seconds
