The number of parents is c -9 since there are 9 more children than parents
And we know that the total number of people in the room is 25 so:
c + c-9 = 25
or
2c - 9 = 25
We can then solve for c
2c = 34
c = 17
I am assuming that the equation is:
based on the answer choices given. As a note, you can write the fraction as (5/2) so that it doesn't just look like 52 (fifty 2).
The equation is written in slope-intercept form. That is, it looks like:
. When written like this the the number in front of x (called the coefficient) is the slope and the number by itself at the end (called the constant) is the y-intercept. If we graphed the line given by the equation the y-intercept is the y-coordinate of the point where the line crosses the y-axis. Here it is 6 and the point is (0,6).
The slope is
. So, what does that mean? The slope tells us something about the "steepness" of the line. It gives the "change is y" over the "change in x." That means that every time the change in y is 5, the change in x is 2. Since the y gives the number of minutes one can run and the x gives the number of laps, what a slope of 5/2 means is that for FOR EVERY 2 LAPS YOU CAN SWIM YOU CAN RUN ANOTHER 5 MINUTES.
If a shape is translated (has it's vertex' coordinates moved/changed), then it retains its original values but just has different vertex coordinates.
Thus since DE is equal to UV, then,
DE = UV; substitution:
5=5
While none of these examples can be used as an counterexample i could make one up to prove the conclusion is false. ex: 3-5=-2
