Step-by-step explanation:
f(x) = 2x - 5
is a line function.
the transformations are not changing the basic structure, so, also g(x) is a line function.
the negative sign reflected/mirrored the original line across the x-axis.
x+1 as argument translates the line 1 unit to the left.
+3 at the end translates the line 3 units up.
Answer:
x=6
Step-by-step explanation:
3x-6=12
+6 +6
3x=18
3x/3= 18/3
x=6
Hope this helps!

Answer:
Length of Arc = 4
Step-by-step explanation:
Circumference is the whole circle's perimeter.
Arc length is a "part" of the circumference.
Whole circle is 360 degrees, so the arc length with a central angle of 72 degrees will be:
72/360 = 1/5th of the whole circle
The whole circle has circumference of "20", so 1/5 th of that would be:
(1/5) * 20 = 4
Length of Arc = 4
