The angles below AB will add to 180°.
.. x +2x +x +3x = 180°
.. 7x = 180°
.. x = 180°/7 ≈ 25.71°

Vertical angles AOC and BOD are equal, so
.. 2y = 3x
.. y = (3/2)*x = (3/2)*25.71° = 38.6° . . . . . . . . corresponding to selection D.

___
There is an "x" missing next to segment OC. "2" should be "2x".

Notice that 2y and 3x are vertical angles, which means they are equal.
2y=3x

the four angles below the line AB make a sum of 180
 3x+x+2x+x=180
7x=180
x=180/7

2y=3x=3*180/7=540/7
y=270/7≈38.6
d is the answer.

Which rule describes the function in the graph below?
m_a_m_a [10]

The function that models the graph is given as:f(x)=\left \{ {{-\frac{1}{3}x+\frac{4}{3}  \ \ -8 < x < 2} \atop {-x^2+6\ \ -2 < x < 0}} \atop {6\ \ 0 < x < 4}, \ \ x+2\ \  4 < x < 7 \right.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

The equation shown in the graph represents a piecewise function. Hence:

From the line through the point (-8, 4) and (-2, 2), the equation is f(x) = -(1/3)x + 4/3

From the curve through the point (-2, 2) and (0, 6), the equation is f(x) = -x² + 6

From the line through the point (0, 6) and (4, 6), the equation is f(x) = -6

From the line through the point (4, 6) and (7, 9), the equation is f(x) = x + 2

The function that models the graph is given as:f(x)=\left \{ {{-\frac{1}{3}x+\frac{4}{3}  \ \ -8 < x < 2} \atop {-x^2+6\ \ -2 < x < 0}} \atop {6\ \ 0 < x < 4}, \ \ x+2\ \  4 < x < 7 \right.
