2x +9 = 3x - 1

2x - 3x = -9 -1

-x = -10

x = 10

2(10) + 9 = 29

so angles 1 and 3 measure 29 degrees

360 - 2(29) = 302 degrees

302/2 = 151 degrees

so angles 1 and 3 measure 151 degrees

2x + 9 = 3x - 1

9 + 1 = 3x - 2x

10 = x

2(10) + 9 = 29

angle 1 and 3 is 29°

180 - angle 3 = angle 4

180 - 29 = 151

angle 4 and 2 is 151°

Which piecewise function is shown in the graph?
mash [69]

Based on the characteristics of <em>linear</em> and <em>piecewise</em> functions, the <em>piecewise</em> function f(x) = \left \{ {{-0.5\cdot x +1, \,x < 0} \atop {2\cdot x - 2, \,x \ge 0}} \right. is shown in the graph attached herein. (Correct choice: A)

<h3>How to determine a piecewise function</h3>

In this question we have a graph formed by two different <em>linear</em> functions. <em>Linear</em> functions are polynomials with grade 1 and which are described by the following formula:

y = m · x + b     (1)

Where:

  • x - Independent variable.
  • y - Dependent variable.
  • m - Slope
  • b - Intercept

By direct observation and by applying (1) we have the following <em>piecewise</em> function:

f(x) = \left \{ {{-0.5\cdot x +1, \,x < 0} \atop {2\cdot x - 2, \,x \ge 0}} \right.

Based on the characteristics of <em>linear</em> and <em>piecewise</em> functions, the <em>piecewise</em> function f(x) = \left \{ {{-0.5\cdot x +1, \,x < 0} \atop {2\cdot x - 2, \,x \ge 0}} \right. is shown in the graph attached herein. (Correct choice: A)
