lilavasa [31]
We will use the Sine Law:
\frac{sin 54.33}{b}= \frac{sin29.16}{3}   \\  b =  \frac{3sin54.33}{sin29.16}
b = 5.001

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

"Add 4 to both sides, and then divide by 2. The solution is x = 12."

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

  • To solve for 'x', we would have to use inverse operations.
  • We would first have to add four to both sides to undo the negative four. Addition is the opposite of subtraction.
  • We would then divide by 2 to isolate 'x'. Division is the opposite of multiplication.

⸻⸻⸻⸻

\boxed{\text{Solving for 'x'...}}\\\\2x - 4 = 20\\------------\\\rightarrow 2x - 4 + 4 = 20 + 4\\\\\rightarrow 2x = 24\\\\\rightarrow \frac{2x=24}{2}\\\\\rightarrow \boxed{x = 12}

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

For the piecewise function, find the values g(-2), g(3), and g(4).
miv72 [106K]

Answer:

g(-2)= -2 + 5 =3  ( here we chose the function g(x)= x+5 as x< 3)

Step-by-step explanation:

g(3)= is not defined ( function is defined for x<3 and x>3 but not x=3)

g(4) = 6-4=2 ( here we chose the function g(x)= 6-x as x> 3)
