Evaluate the function f\left(x\right)=5x+2\mid11-5x\mid-4f(x)=5x+2∣11−5x∣−4 for x = -5.

Anestetic [448]

Answer:

$f\left(5\right) = 43$

Step-by-step explanation:

Given

$f\left(x\right)=5x+2\mid11-5x\mid-4$

Required

Solve for x = -5

This implies that we substitute -5 for x in $f\left(x\right)=5x+2\mid11-5x\mid-4$

$f\left(5\right)=5(-5)+2\mid11-5(-5)\mid-4$

Open all brackets

$f\left(5\right) = -25+2\mid11+25\mid-4$

$f\left(5\right) = -25+2\mid36\mid-4$

Absolute value of 36 is 36; Wo, we have:

$f\left(5\right) = -25+2*36-4$

$f\left(5\right) = -25+72-4$

$f\left(5\right) = 43$

2 of the dozen eggs in a cartoon are cracked about what percent of the carton is not cracked

pychu [463]

well, a carton has a dozen, namely 12 or the 100%, two were cracked.

if we know 12 is the 100%, what is 2 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\cline{1-2}
12&100\\
2&x
\end{array}\implies \cfrac{12}{2}=\cfrac{100}{x}\implies x=\cfrac{2\cdot 100}{12}\implies x=16.\overline{66}$

A bicycle store costs $3300 per month to operate. The store pays an average of $75 per bike. The average selling price of each

Klio2033 [76]

S=Selling price 135
V=Variable cost 75
F=Fixed cost 3300
Let quantity be Q
The formula to break even is
135Q-75Q-3300=0
Solve for Q
60Q-3300=0
60Q=3300
Q=3300/60
Q=50
So the store must sell 50 bicycles to break even

Hope it helps!
