Answer:

Option (a) and (d) are correct.

Step-by-step explanation:

Given : A line segment AC with B a point on it and DB making an another line segment.

We have to name the type of angle shown.

Straight angle : is an angle made by a straight line. Measure of straight angle is 180°

Right angle: is the angle whose measure is 90°

Complementary angles: are two angles whose sum is 90°

Supplementary angles: are two angles whose sum is 180°

Here, ABC forms a straight angle.

and ∠ABD + ∠DBC = 180°

Thus, ∠ABD and ∠DBC forms a pair of supplementary angles.

Option (a) and (d) are correct.

Hi there!

$\large\boxed{\left \{ {{y\geq -x + 3} \atop {y > 2x - 3}} \right.}$

We can begin by looking at the solid-line pictured in the graph.

Using the slope-formula, we can derive the slope from this line:

$\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 }$

Plug in points from the line:

$m = \frac{0- 3 } { 3 - 0} = -1$

We can also see that the graph has a y-intercept, or "b" value of 3. The line is a solid line including values above it, which means we must use a "greater than or equal to" symbol. Therefore, the final equation is:

y ≥ -x + 3

The second line is dashed and also has values shaded above its graph. We can use this later to make an equation, but let's solve for the slope for now. Use the same equation as above:

$m = \frac{1-(-3)}{2-0} = 4/2 = 2$
