In this question , we have to simplify the given ratio, which is
12xy:3x
First we have to see which factor is common in numerator and denominator,
We can write 12 as 3 times 4, that is
So the common factor is 3x.
In the next step, we cancel out 3x
And that's the required simplified form .
The answer is (-2, 10) because when reflecting over the x, change the sign of y. When reflecting over the y, change the sign of x.
You're assuming that this data set represents all of Mrs. Hassaan's pupils. Certain students could be missing from the histogram - for instance, there could be one or two students who missed the test, but for certain reasons will be taking a make-up exam. Their grade would not be recording in this data set, but they still contribute to the class size, and so would be unaccounted for here.
First, graph 3,-5 [RED]
then, reverse the x coordinate {3} (it is now at -3,-5) [BLUE]
next, move the point 6 to the right and 7 to the left (it is now at 3,2) [GREEN]
then, reverse the x coordinate {3}<span> (it is now at -3,2) [ORANGE]
</span>
finally, connect the dots.
