First, draw a circle with point U as the center point and point S as the end of the radius. Then, draw another circle with point D as the center point and the radius length equal to US. Next, draw ray DE away from angle SUN. Finally, draw angle SUN.
Y=2x^3 is nonlinear, since it's a cube equation. y=x+5 is linear, because it's a line with y intercept (0,-5) and slope 1. y=\sqrt(x-5) is nonlinear, because it's a quadratic equation when reversing x and y. 5x+5y=25 is equal to x+y=5 ot y=-x+5, which is also linear. y=x^2/2 is a quadratic equation, so it's nonlinear.
. The answer is 21.
Step-by-step explanation:
16*8=128 and 128*12= is 1,536
Let
be the two numbers. We have two pieces of information:
(the difference between the two numbers is 2)
(their product is 224)
From the first equation, we can deduce 
If we plug this expression in the second equation, we have

If you solve this equation with the usual quadratic formula you get the solutions

So, you have the following couple of solutions, recalling that x is 2 more than y:
