Answer:
-142
Step-by-step explanation:
You seem to have an arithmetic sequence with first term -66 and common difference (-68-(-66)) = -2. The general term of such a sequence is given by ...
an = a1 +d(n -1) . . . . . for first term a1 and common difference d
We want to evaluate this equation for a1 = -66, d = -2, n = 39:
a39 = -66 -2(39 -1) = -66 -76 = -142
The 39th term is -142.
When Triangle ABC is reflected on the x-axis the new coordinates are A (-3,-1) B(-1,-3) C(-2,-1)
However the Triangle is then translated 4 units up, so the New and Final coordinates for Triangle ABC is A(-3,3) B(-1,0) and C(-2,4)
Hope this helps

Answer:
8
Step-by-step explanation:
There are several ways of doing that, but probably the simplest one is to use the formula
where the vertices are
and the bars | | means that you take the positive value of the number inside. For example | -3 | = 3.
Our vertices are
Replace the values in the formula and we have
