Hi! So, I've got a question. My Math problem is a 2 part problem. Let me just write it out real quick.


"Two students are reading a book. Keith reads 6 pages a day. Tameka reads 5 pages a day, but he starts sooner and has already read 15 pages.


Part A


Write a system or equations to represent the situation, using d for days and p for pages.


Part B


Graph the system of equations.


The graph's Y axis counts up by ten's. 0, 10, 20, 30, 40, etc all the way to one hundred. The x-axis counts by five's, all the way to 25.


Part C


Will Keith and Tameka ever be on the same day? Explain?"


Here's the part that confuses me. My teacher writes down little notes on our sheets, telling us what is required to receive full credit. For the graphing part, she lists there is two lines that we need. I don't know what lines she would be talking about. I only have one equation. Is anyone able to help?

Respuesta :

Okay!

This problem is a systems of equations - graphically, your answer will be where all the lines in the problem/system intersect.

You are given two rates at the beginning of the problem:

Keith's rate: 6 pages a day

Tameka's rate: 5 pages a day, 15 page headstart.

When you are given a rate, that is automatically a line! That's what makes these systems of equations really neat.

Try taking Keith and Tameka's rates individually and come up with an equation for the both of them, and then put the two on a graph.

(hint: substitute x for pages)

Good luck!
