Someone please help me on these 2 problems!

Mathematics

1) function  2) not a function

the first one is a function because its y values are the same number (3), which means it is a horizontal line and horizontal lines are functions.  

the second one is not a function because the coordinates cannot have different inputs but different outputs. each input must have only one output.

the coordinates for the second one are:

(2,5); (1,1); (1,2); (3,2)

and <u>a function cannot have two same x-coordinates</u>. it must pass the vertical line test which is a way to tell if something is a function or not. since the second graph does not pass the vertical line test, it is not a function

hope this helps :)

In the figure, . Find x and y.
zloy xaker [14]

Answer:

The answer to your question is x = 52° and y = 137°

Step-by-step explanation:

Process

1.- Find the value of x using the large right triangle, remember that the sum of the internal angles in a triangle equals 180°.

   x  + 38 + 90 = 180

  x = 180 - 90 - 38

  x = 52°

2.- To find y, we notice that x and y -9 are supplementary angles so their sum gives 180°.

           x + y - 9 = 180

Substitution

          52 + y - 9 = 180

          y = 180 + 9 - 52

          y = 137°

Russell runs 9/10 mile in 5 minutes. At this rate, how many miles can he run in one minute?
miss Akunina [59]
9/50 is the answer I think!

I converted 9/10 to decimal to make it easier for me to solve and got 0.9

I divided 0.9 by 5 and got 0.18

I converted 0.18 to fraction and got 9/50

How many unique triangles can be formed with two side lengths of 10 centimeters and one 40° angle?
r-ruslan [8.4K]

Answer:

  • Two unique triangles possible

Step-by-step explanation:

Given two sides of 10 cm and one 40° angle

<u>If we use these, we'll get isosceles triangle with:</u>

1. Included 40° angle.

<u>Then the other angles will be same and measure:</u>

  • (180° - 40°)/2 = 70°

2. Adjacent 40° angle. Then one of the angles must be 40° angle as opposite of 10 cm sides.

<u>The remaining angle will measure:</u>

  • 180° - 2*40° = 100°

There no more unique triangles possible, so the answer is two.

Carly draws quadrilateral JKLM with vertices J(-3,3), K(3,3), L(2,-1),and M(-2, -1). What is the best way to classify the quadri
Trava [24]

Answer:

Trapezoid

Step-by-step explanation:

The points are shown in the attached graph.

<em>You can clearly see from the picture that it is a "Trapezoid".</em>

<em />

<em>Trapezoid</em><em> is basically a quadrilateral (4 sided-figure) that has 1/2 pair of parallel sides.</em>

<em>On the other hand, a </em><em>parallelogram</em><em> has 2 pair of parallel sides.</em>

<em />

Thus, a parallelogram is a special type of trapezoid where there are 2 pair of parallel sides. But trapezoid need not be a parallelogram.

<em>The picture shows 1 pair of parallel sides, hence it is a </em><em>trapezoid.</em>
