Solve for x.

∑ Hey, KLPJDP615 ⊃

Answer:

x = 6 or x = -10

Step-by-step explanation:

<u><em>Given:</em></u>

<em>Solve for x.</em>

<em>1 + |2+x|= 9</em>

<em>O x = 4 or x = -8</em>

<em>O x = 7 or X = -11</em>

<em>O x = 5 or x = -9</em>

<em>x = 6 or X = -10 </em>

<u><em>Solve:</em></u>

<em>1 + |2+x|= 9</em>

<em>Subtract 1 from both sides:</em>

<em>1 + |2 +x| -1 = 9-1 </em>

<em>Simplify</em>

<em>|2 + x | = 8</em>

<em>Applying absolute value rule:  If |u| = a, a > 0 then u = a or u = -a</em>

<em>2 + x = -8</em>

<em>2 + x = 8</em>

<u><em>Solving:</em></u>

<em>2 + x = -8</em>

<em>2 - 2 + x = -8 - 2</em>

<em>x = -10</em>

<u><em>Solving:</em></u>

<em>2 + x = 8</em>

<em>2 - 2 + x = 8 - 2</em>

<em>x = 6</em>

<em />

<em>Hence, x = 6 or x = -10</em>

<em />

<u><em>xcookiex12</em></u>

<h3>What is a line graph?</h3>

A line graph is a graph made up of segments of straight lines that connect the depicted data points.

We have:

An auto mechanic charges (C) an initial fee of $50 and then $40 per hour.

Let T be the total fee and h is the number of hours

T = 50 + 40h

The above equation represents a graph of a straight line as the slope of the line is positive.

m = 50

Thus, the graph of this model would be a straight line that increases only option third is correct.
