Answer:

Slope formula: y2-y1/x2-x1

Step-by-step explanation:

8-6/9-6= 2/0

Answer:

Step-by-step explanation:

Alright we need to prove that both the triangles are similar so lets get started

The slope formula is:

Slope = Change in y / Change in x

m = Δy / Δx

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\[/tex]

Where, m is the slope and [tex](x_1,y_1) , (x_2,y_2)\\[/tex] are any points on the line

In this graph we are given three points which are

(0 , 2) , ( 6 , 6) and (9 , 8)

So for our first triangle we use the 2 points (0 , 2) and (6 ,6) and calculate the slope,

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{6-2}{6-0}\\\\m=4/6\\\\m=2/3\\[/tex]

So the slope turns out to be 2/3 , Now for our second triangle use the 2 points (6 , 6) and (9 , 8)

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-6}{9-6}\\\\m=2/3\\[/tex]

So we can see the the slope's are equal that's the answer to your first part.

Second part

Yes they are similar due to the property of corresponding angles where angle x of the first triangle equals angle x for the second triangle and angle y for the first triangle equals angle y for the second triangle and both the triangles have 90° se they are similar because all three angles are similar. (AAA = angle angle angle property) I have attached a to make you understand it better.

7.5d = 2.5d Lin divided each side by 2.5d and Elena subtracted 2.5d from each side with both leads to the solution

Answers

Answer:

Elena's move will lead to the solution of the problem

Step-by-step explanation:

To solve the equation 7.5d=2.5d, Lin divides each side by 2.5d, and Elena subtracts 2.5d from each side. Will both moves lead to the solution? Explain your reasoning

Given:

7.5d = 2.5d

Lin divides each side by 2.5d, Lin:

7.5d / 2.5d = 2.5d / 2.5d

3 = 1

This can not be the solution to the problem because 3 can not be Equal to 1

Elena subtracts 2.5d from each side

7.5d = 2.5d

7.5d - 2.5d = 2.5d - 2.5d

5d = 0

This can lead to the solution of the problem

Elena's move will lead to the solution of the problem

Answers

Answer:

So 180-94 =86 so then it becomes 60°, 86°, and 2x so you would then add 60 and 86 together and get 146 and 180 - 146 is 34 then divide by two and you get 17 so x=17°

Step-by-step explanation:

Sorry if that’s confusing

Answer:

x = 17

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

94° is an exterior angle of the triangle, thus

2x + 60 = 94 ( subtract 60 from both sides )

2x = 34 ( divide both sides by 2 )

x = 17

3

Step-by-step explanation:

The difference between the y coordinates is 6.

The difference between the x coordinates is 2

The slope is rise over run so in this case, the rise is 6 and the run is 2.

This makes our slope:

6/2

This can be simplified to 3/1 so the slope is 3.

A function is defined as for every input their is a certain output.Function is a type of relation, or rule, that maps one input to specific single output.

Here, we have a-5=-4b+13

a−5=−4b+13

a = -4b + 13+ 5

a = -4b +18

Thus, the required function h(a) is a = -4b +18

to find the answer, you need to find the measure of the angle on the other side of the 142. and since it's a straight line, those two angles measures are =to 180 (they're supplementary angles). so the measure of that angle is 38 degrees. to find the measure of the remaining angle, you subtract the angle measures you already know from 180 (because the sum of interior angles in a triangle is 180.) to, the answer is:

180-90-38= 52 degrees or A
