Answer:
y= -10
Step-by-step explanation:
1. Add 12 to both sides to get 30= -3y
2. Divide both sides by -3
3. y = -10
The meaning of the question is
Let the unknown number be x
Therefore x+7=16-2x
Now 2x+x=16-7
3x=9
X=9/3
x=3
Answer:
Step-by-step explanation:
hello :
x²+ y² -12x - 18y +17 = 0 means : (x²-12x+36)-36+(y²-18y+81)-81-27 =0
(x-6)²+(y-9)² =12²....standard form when the center is (-6 , 9) and radius 12
Answer:
[2]x + [1]
Step-by-step explanation:
f(g(x)) = f(2x) = 2x + 1
so f(g(x) = [2]x + [1]
