Answer:
Describes f(x) = |x|, the graph opens up, the range is greater than 0, vertex is at 0,0, the domain is greater than 0
does not describe f(x) = |x|, is symmetric to the x axis, and is increasing over (0, arrow)
Step-by-step explanation:
punch the equation into desmos, I didn't cuz I know that the equation looks like, but you can visualize with any graphing calculator
4.7a+8.2a-6.5a=0
We simplify the equation to the form, which is simple to understand
4.7a+8.2a-6.5a=0
We move all terms containing a to the left and all other terms to the right.
+4.7a+8.2a-6.5a=0
We simplify left and right side of the equation.
+6.4a=0
We divide both sides of the equation by 6.4 to get a.
a=0
Answer:
None
Step-by-step explanation:
The sum of the inner angles of a triangle must be 180. Instead, you have

So, a figure with these angles can't be a triangle.
