Answer:
<h2>x = 1, y = 3 → (1, 3)</h2>
Step-by-step explanation:
A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 20 is about 4.472. Thus, the square root of 20 is not an integer, and therefore 20 is not a square number.
Answer:
y=4/5x
Step-by-step explanation:
y=mx+b
plug in y and x into each equation and solve!
4=5m+b
8=10m+b
4=5m
m=4/5
b=0
y=4/5x+0
The vertex form:
The axis of symetry is x = h.
We have
Substitute:
<h3>Answer: x = -3</h3>
If you separate the triangles, you'll notice that both are literally the same triangle because all angles are the same.
