Answer:

<h2>A. the altitude of a hiker who climbs up a mountain at a constant rate and then rests at the top of the mountain.</h2>

Step-by-step explanation:

The given graph shows a increasing linear behaviour, then it shows a null behaviour.

So, if the graph is about a hiker, then the first part of it expresses that the hiker climbed up, and then rested, because the horizontal part means that there wasn't any move during that period.

Therefore, the right answer is A.

Remember that in a linear graph, horizontal periods of the line means the absence of any ratio of change, so if variables are time and distance, the horizontal part means that the person didn't move during that period.

Now, if the line increases, means that the person was moving forward, that's why the right choice is A.

Answer:

D. the total distance a vehicle travels as it goes up a hill and then maintains a constant rate of speed at the top.

even if the distance increases the graph should rise up.

a student found the slope of a line that passes through the points (1,14) and (3,4) to be 5. what mistake did she make?

mariarad [96]

$x_{1}=1$
$x_{2}= 3$
$y_{1} =14$
$y_{2}=4$
$Slope= \frac{rise}{run} = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } = \frac{4-14}{3-1} = \frac{-10}{2} =-5$

answer: The student flipped the y values

Which pair of angles is an example of supplementary angles?

artcher [175]

Answer:

A. Angle 1 and Angle 7

Step-by-step explanation:

Those two are the only angles that when added up, the sum is 180.

Angle 7 and Angle 2 are also congruent, so if Angle two forms a straight line with Angle 1, Angle 7 should be able to do that too.

Can someone please help with #16

ollegr [7]

Answer:

∠ WZX = 50°

XW is not an altitude.

Step-by-step explanation:

16. See the attached figure.

XW is the angle bisector of ∠ YXZ, hence, ∠ WXY = ∠ WXZ

Now, given that ∠ YXZ = 8x + 34 and ∠ WXY = 10x - 13

Hence, ∠ YXZ = 2 ∠ WXY

⇒ 8x + 34 = 2(10x - 13)

⇒ 8x + 34 = 20x - 26

⇒ 12x = 60

⇒ x = 5.

Hence, ∠ XZY = ∠ WZX = 10x = 50° (Answer)

Now, ∠ WXZ = ∠ WXY = 10x - 13 = 37°

Hence, from Δ WXZ,

∠ WZX + ∠ WXZ + ∠ XWZ = 180°

⇒ 50° + 37° + ∠ XWZ = 180°

⇒ ∠ XWZ = 93° ≠ 90°

Hence, XW is not an altitude. (Answer)
