1. 2(4x - 3) - 8 = 4 + 2x<br> Can sb help slove this using PEMDAS ?

velikii [3]

Answer:

x=3

Step-by-step explanation:

1) get rid of the parenthesis by distributing the 2. You will get 8x-6-8=4+2x

2) Now combine like term on each side of the equal sign. You will get 8x-14=4+2x

3) Move the 14 to the right side of the equation making it +14 and move your 2x to the left side of the equation making it -2x. You will get 8x-2x=4=+14

4) calculate each side. You will get 6x=18

5) Divide both sides. You will get x=3

Find the inverse of the function f(x) = (x - 4) 2 - 5 if x ≥ 4.

Serggg [28]

Same here, we do a quick switcharoo on the variables first,

$\bf \stackrel{f(x)}{y}=(x-4)^2-5\qquad inverse\implies \boxed{x}=\left( \boxed{y}-4 \right)^2-5
\\\\\\
x+5=(y-4)^2\implies \pm\sqrt{x+5}=y-4\implies \pm\sqrt{x+5}+4=y$
