Which statement is true about f(x)-2/3lx+4l-6?
slamgirl [31]
1) Taking in account that the function is f(x)= -(2/3) |x+4|-6, I enclose a file with the graph.

That helps you to conclude:

a) The graph of f(x) has a vertex on (-4, -6)

b) When you multiply a function times 2/3 it is vertically compressed which is equivalent to horizontally streched.

c) The graph of f(x) opens downward

d) The domain of f(x) is all the real values (the absolute function accepts any value of x either positive or negative)

Answer: the graph of f(x) is horizontally stretched.

A radio is being discounted 20%. If the sale price is $51.44, what was the original price of the radio? A. $12.86, B. 64.30, C.
katrin2010 [14]
The equation for decreasing a price by 20% is 
original price x 0.8 = sale price

Here, we can fill in the sale price so
original price x 0.8 = 51.44

This can be rearranged to show:
51.44 ÷ 0.8 = original price

So the original price was $64.30

Answer = B - $64.30
