Answer:
Apply the SAS postulate (see details below).
Step-by-step explanation:
(1) because triangles ABC and BCD share one side BC, both are right-angled, and we are given that |AC|=|BD|, by the Pythagorean theorem, we know that also the third sides are congruent: |AB|=|CD|.
(2) By application of the SAS postulate, where the two sides |AB|=|CD|, |CB|=|CB|, and the included angle <ABC=<CBD, it follows that the triangles ABC and BCD are congruent.
(I am using |..| notation for length of a segment)
Answer:
x=7(y-5)/3 +7
Step-by-step explanation:
y-5=3(x-7)/7
(y-5)×7=3(x-7)
7(x-7)=3(x-7)
7(y-5)/3=x-7
7(y-5)/3+7=x
Answer: 8x + 4
Step-by-step explanation:
Answer:
The output (y-value) when x = 2
Step-by-step explanation:
You have a function y = f(x).
Then f(2) means that you substitute x = 2 into f(x) to work out the output y.
Hope this helps!
