Answer:
These angles are called angle pairs. ... Supplementary angles are two angles whose sum is equal to \begin{align*}180^\circ\end{align*}. In other words when you add the measure of one angle in the pair with the other angle in the pair, they equal 180 degrees.

If an equation is at x=4, that means that it is a vertical (straight up) line at x=4.
A straight, vertical line is NOT 0. Since we're dividing by 0, the slope would be undefined.
Answer:
To use a paired t-test
Step-by-step explanation:
t-tests are essentially tests carried out to compare two different groups to check if there is a major difference in their performances or results which may be related in certain characteristics.
A paired (correlated) t-test is used when there are matched pair of similar units or instances of repeated measurements.
In this case, Mary has to use a paired t-test because the samples (students) have high similarity in characteristics. The students in question has to be from the same class to test her hypothesis (similar characteristics).
Hey there!!
3 ( x - 6 ) + 15 = 4 ( x - 1 ) + 4
3x - 18 + 15 = 4x - 4 + 4
3x - 3 = 4x
- 3 = x
x = -3
The mistake is , you have written -4 + 4 = 8
- 4 + 4 = 0
and - 18 + 15 = - 3 ( not - 33 )
correct it, you will get it
Hope helps!
