X^-2+4x^-1+3=0 solve by making appropriate substitution
Alex

ANSWER

x =  - 1 \: or \: x =  -  \frac{1}{ 3}

EXPLANATION

The given equation is:

{x}^{ - 2}  + 4 {x}^{ - 1}  + 3 = 0

Recall that:

{a}^{ - m}  =  \frac{1}{ {a}^{m} }

\frac{1}{ {x}^{2} }  +  \frac{4}{x}  + 3 = 0

Or

{( \frac{1}{x} )}^{2}  + 4( \frac{1}{x} ) + 3 = 0

Let

u =  \frac{1}{x}

Our equation then becomes:

{u}^{2}  + 4u + 3 = 0

The factors of 3 that add up to 4 are:

{u}^{2}  + 3u + u + 3

u(u + 3) + 1(u + 3) = 0

(u + 1)(u + 3) = 0

u + 1 = 0 \: or \: u + 3 = 0

u =  - 1 \: or \: u =  - 3

This implies that:

\frac{1}{x}  =  - 1 \: or \:  \frac{1}{x}  =  - 3

x =  - 1 \: or \: x =  -  \frac{1}{ 3}

Given:

Fixed salary earned by Jeanette per week = \$425

Additional amount earned by her for each sign she sells = \$30

To find: linear equation which represents her weekly pay based on the number of signs she sells.

Not sure how I can solve this problem or where to start. Please Help!
Artyom0805 [142]

The triangle on the left side has two legs of length 4 m and 6 m. It's a right triangle, so the hypotenuse has length √((4 m)² + (6 m)²) = 2√13 m. Only the 4 m leg and the hypotenuse count towards the shape's overall perimeter.

The rectangular part contributes 9 m from the top side and 9 m from the bottom one, thus a total of 18 m.

The half-circle has diameter 6 m (indicated by the dashed line, same as the height of the triangle on the left). A full circle with diameter <em>d</em> has circumference <em>πd </em>; a half-circle with the same diameter would then contirubte <em>πd</em>/2, or in this case, 3<em>π</em> m.

So, the total perimeter of the shape is

(4 m + 2√13 m) + 18 m + 3<em>π</em> m ≈ 38.6 m
