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
Answer:
The expression is: 100 -a - 2b
Step-by-step explanation:
One piece of length a and two pieces of length b, i.e., (2 times b) are a total length of (a + 2b). We are asked to express the remaining part of the wire, originally 100 cm long, so that must be 100 minus the total pieces cut out:
100 - ( a + 2b ) = 100 -a -2b
Answer:
A?? because I think it's not linear because it's not proportional
the mean can be misleading, because there outlier (77), which is not close to the ages of the others, thereby changing the mean drastically.
hope this helps
