400 - 2x = 244
-2x = 244 - 400
-2x = -156
x = -156 / -2
x = 78
Answer:
domain is all real numbers
range is y is less than or equal to 1 (it is a downward parabola)
Answer: See below
Step-by-step explanation:
A) 


Multiply both sides by -1 and reverse the inequality:


B) 




We can start by getting rid of parenthesis:
4x-3x+6=21
Then we can combine like terms:
x=21-6
x=15
So our end product is x=15.
Hope I helped soz if I'm wrong ouo.

We need to find the value of the hypotenuse in order to solve this problem.
12^2+4^2=H^2
Therefore:
H=√(144+16)
H=4√10
Now:
sin(G)=O/H=4/(4√10)
=1/(√10)
=(√10)/10
