Derek measured the height of a window frame as 5.49 feet, but the actual height was 6 feet. What is the percentage of error in D

KIM [24]

Actual = 6 feet.

Measure = 5.49 feet

Error = 6 - 5.49 = 0.51

% Error = (Error / Actual) * 100%

= 0.51/6 * 100% = 8.5%

Alonzo wrote the equation x=2+4y-5 solve for y

kati45 [8]

if x= 2+4y-5 then x-2 +5 = 4y so y = (x-2+5) /4 = ( x+3) /4

conclusion y = (x+3)/4

Answer: x = 8

(the correct answer was not provided as an option)

<u>Step-by-step explanation:</u>

$log_2(x-6)+log_2(x-4)=log_2(x)\\\\log_2[(x-6)(x-4)]=log_2(x)\\\\(x-6)(x-4)=x\\\\x^2-10x+24=x\\\\x^2-11x+24=0\\\\(x-3)(x-8)=0\\\\x=3\qquad x=8\\\\\\\text{The term after the log symbol (inside the parenthesis) must be greater than 0!}\\\\Check:\\3-6>0\ \text{FALSE --- so 3 is not a valid solution}\\\\8-6>0\ \text{TRUE}\\8-4>0\ \text{TRUE}\\8>0\ \text{TRUE --- 8 is a valid solution because it is true for all}$
