Answer:
-2/7
Step-by-step explanation:
Going from (7,-1) to ( 21,-5) we see x (the 'run') increasing by 14 and y (the 'rise') decreasing by 4. Thus, the slope of the line connecting these two points is m = rise/run = -4/14, or -2/7.
Answer:
not similar; corresponding sides are not proportional
Step-by-step explanation:
If the triangles were similar, corresponding sides would be proportional. That is, you would have ...
AX/AB = AY/AC
Here, those ratios are ...
6/24 ≠ 10/35
so, the corresponding sides are not proportional, and the triangles are not similar.

Answer:
Given function is decreasing for all x-values , except 4.
Step-by-step explanation:
We are given with a graph of the function and we are asked to find x-values for which function is decreasing.
We will say a function is decreasing If as x increases(from left to right) y decreases(goes down).
The given graph has 2 regions till x=4 and after x=4
Till x=4, if we see the graph from left to right, graph is going down, which means it is decreasing.
After x=4 also, as x goes from left to right, graph is going down, which means it is decreasing after x=4 also.
Hence the given function is decreasing for all x-values except x=4.
Answer:
Step-by-step explanation:
A = 8 cm
B = 5 cm
C = 22 - 8 - 5 = 9 cm
Use the Pythagreom Theroem (a^2 + b^2 = c^2) if the two sides are equal to one another than it is a right triangle.
8^2 + 5^2 = 9^2
64 + 25 = 81
89 = 81
89 does not equal 81, so this is not a right triangle.
