-23.2 I think this is the answer
M(h)=5h
that is marcia's number of candles where she makes 5 candles per hour (h)
kevin makes 4 but already did 7 so
k(h)=4h+7
when will they have same numbre of candles?
when will m(h)=k(h)
set equal
5h=4h+7
minus 4h from both sides
1h=7
answer is 7 hours
system of equation is
m=5h
k=4h+7
find what value of h makes m=k true
answer is 7 hours

Answer:
-8/5
Step-by-step explanation:
The thing that makes lines different from other kinds of curves is their <em>constant rate of change</em>. We call this rate of change <em>slope</em>, and you usually see it represented with the letter <em>m</em>. We measure it as the rate our y-coordinate changes for some amount our x-coordinate changes.
We're given the two points (-1, 4), and (4, -4). From that first point to the second one, our x-coordinate <em>increases </em>by 5, while our y-coordinate <em>decreases </em>by 8, so our change in y is -8 for every 5 in the positive x direction, and we'd write our slope as
m = -8/5
