Solve | x + 6| - 7 = 8
Alex

Answer:

x = 9,-21

Step-by-step explanation:

Given:

\displaystyle \large{|x+6|-7=8}

Transport -7 to add 8:

\displaystyle \large{|x+6|=8+7}\\\displaystyle \large{|x+6|=15}

Cancel absolute sign and add plus-minus to 15:

\displaystyle \large{x+6=\pm 15}

Transport 6 to subtract ±15:

\displaystyle \large{x=\pm 15-6}

Consider:

\displaystyle \large{x= 15-6} or \displaystyle \large{x = -15-6}

\displaystyle \large{x=9} or \displaystyle \large{x=-21}

Solution:

\displaystyle \large{x = 9} or \displaystyle \large{x=-21}

Second Method

Given:

\displaystyle \large{|x+6|-7=8}

Transport -7 to add 8:

\displaystyle \large{|x+6|=8+7}\\\displaystyle \large{|x+6|=15}

Absolute Function Property:

\displaystyle \large{|x-a| = \begin{cases} x-a \ \ (x \geq a) \\ -x+a \ \ (x < a) \end{cases}}

Consider both intervals:

When x ≥ a then:

\displaystyle \large{|x+6|=15}\\\displaystyle \large{x+6=15}

Transport 6 to subtract 15:

\displaystyle \large{x=15-6}\\\displaystyle \large{x=9}

When x < a then:

\displaystyle \large{|x+6|=15}\\\displaystyle \large{-(x+6)=15}\\\displaystyle \large{-x-6=15}

Transport -6 to add 15:

\displaystyle \large{-x=15+6}\\\displaystyle \large{-x=21}

Transport negative sign to 21:

\displaystyle \large{x=-21}

Solution:

\displaystyle \large{x=9} or \displaystyle \large{x=-21}

Points A and B are on opposite sides of a lake. A point C is 105.6 meters from A. The measure of ∠BAC is 70.5°, and the measure
nignag [31]

Answer:

= 70 Meters

Step-by-step explanation:

We can use the sine rule as follows:

Angle ABC=180-(70.5+38.833)

=70.667°

Using the sine rule and sides AB, AC and angles ABC and ACB:

b/Sin B=c/Sin C

Replacing with the values above we get:

AC/Sin ABC= AB/Sin ACB

105.6/Sin 70.667=AB/Sin 38.833

AB=(105.6 Sin 38.833)/Sin 70.667

=70.17 meters

The distance between the two points to the nearest meter is 70 meters
