Answer:

x = -35.7142

Step-by-step explanation:

$f(x)=\frac{-25x}{x-6}\\\\f(20)=\frac{-25(20)}{20-6}\\\\f(20)=\frac{-500}{14}\\\\f(20)=-35.7142$

What is the value of x? Enter your answer in the box. __mm

You can set up a ratio as follows:
$\frac{x-22}{87.5}= \frac{22}{77}$

Solve for x by cross-multiplying:
$(x-22)(77) = (87.5)(22)$
$x = \frac{(87.5)(22)}{77} + 22= 47.01$

Since we need the answer in mm and right now we have it in feet, we need a conversion ratio. After googling it, the conversion ratio is: 1ft = 304.8mm
$47.01(304.8) = 14326.64$

So, the answer is 14326.64 mm.

Solve the absolute value equation. |3x| = 12 A. {4, 4} B. {4, –4} C. {–4, –4} D. no solution

AlekseyPX

|3x| = 12 actually represents two equations: 3x = 12 and -3x = 12.

Thus, the solutions are {-4, 4).
