Y=2x^3 is nonlinear. This is a cubic function.
y = x + 5 is linear.
y = sqrt(x-3) is also nonlinear
5x + 5y = 25 is linear. It simplifies to y = -x + 5 if you want it in slope-intercept form
y = x^2 / 2 is nonlinear
Hope this helps
Since this number ends with a .59, this means that we should round 156.59 to 157.00. But because we never use .00 unless we are dealing with money, it's just better to say 157 instead of 157.00.
Hope this helps!

Answer:</h3>
f((x, y)) = (-y, -x)
<h3>
Step-by-step explanation:</h3>
Rotation 90° CCW about the origin is the mapping ...
... (x, y) ⇒ (-y, x)
Reflection across the x-axis is the mapping ...
... (x, y) ⇒ (x, -y)
Together, these do the following mapping:
... (x, y) ⇒ (-y, -x) . . . . . . . equivalent to a reflection across y = -x
Expressed as a function, this might be written ...
... f((x, y)) = (-y, -x) . . . . . . . the ordered pair argument becomes a new ordered pair
The answer is b. 19.42. :)
Answer:
C. 11, 1
Step-by-step explanation:
I could have sworn I already answered this. Oh well. I guess I can answer it again. Simply plug in -3 and 3 for <em>x</em><em>,</em><em> </em>then find<em> </em>the absolute value [ALWAYS POSITIVE].
