A conjecture and the flowchart proof used to prove the conjecture are shown.

Given: A B C D is a parallelogram. Prove: Angle 1 is supplementary to angle 3. Art: Parallelogram A B C D. Ray D B is drawn and is extended past vertex B. The ray forms an interior angles A D B and D B C and an exterior angle labeled as 3, adjacent to angle D B C. Angle A D B is labeled as 1, and angle D B C is labeled as 2.

5. Definition of supplementary

∠1 is supplementary to ∠3 by the Definition of supplementary angles

What are supplementary angles?

Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line.

Prove: Angle 1 is supplementary to angle 3.

Given information as; ABCD is a parallelogram.

Proof:

∠1 = ∠ADB

∠2 = ∠DBC

∠3 = the exterior angle adjacent to angle D B C.

Statement Reason

∠2 is supplementary to ∠3 Linear pairs

m∠2+m∠3=180° Definition of supplementary angles

m<1 + m<3 = 180 Alternative interior angles

m∠1+m∠3=180° Substitute property of equality

∠1 is supplementary to ∠3 Definition of supplementary angles

Therefore, we can conclude that ∠1 is supplementary to ∠3 by the Definition of supplementary angles.

Find the slope of the line passing through each of the following pairs of points.
(0, -8), (0,4)

Answers

Answer:

The slope is undefined

Step-by-step explanation:

You can find the slope by doing change in y/change in x.

Y changed by 12 units while x changed by 0.

12/0 is undefined, so the slope is as well (on a graph, the line would be vertical)

0 or undefined or infinity

Step by step explanation:

slope = y2 - y1 / x2 - x1

= 4 + 8 / 0 + 0

= 12 / 0

= 0

3/0.8 = z/5.6

Solve for z

Answers

3 / 0.8 = z / 5.6

To find z, we need to isolate z. How can we do this? Right now, we know z / 5.6 is equal to 3 / 0.8.

To isolate z, we should multiply by 5.6 on each side.

This will cancel the divide by 5.6 or the 1/5.6 on the right side to isolate z!

(3 × 5.6) / 0.8 = z

16.8 / 0.8 = z

All we have to is simplify!

z = 21

Are x(3x) and 4x equivalent?

Answers

Answer:

They are not equivalent.

Step-by-step explanation:

x(3x) = 4x

x by itself = 1x

1x ( 3x ) = 4x

1x times 3x = 3x

3x = 4x is not equivalent.

Where is the shading in the graph of the quadratic inequality y > -22 + 6x + 3? Why?

Answers

Answer:

Check Graph below

Step-by-step explanation:

y > -22 + 6x + 3

Add -22 and 3.

y > 6x - 19

Use the slope-intercept form to find the slope and y-intercept.

Slope: 6

y-intercept: (0,-19)

Graph a dashed line, then shade the area above the boundary line since y is greater than 6x − 19 .

y > 6x - 19

Bastian was able to map triangle ABC onto triangle A'B'C' using a reflection, rotation, and a dilation. Then Bastian concluded that he was able to map triangle ABC onto triangle A'B'C' using a sequence of rigid transformations and dilations, so the triangles are similar. What error did Bastian make in his conclusion?

Bastian used a rotation, so the triangles aren't similar.

Bastian used a combination of similarity transformations, which can produce a non-similar result.

There is no error. This is a correct conclusion.

Bastian used a dilation, which does not preserve similarity.

A string measures 30 centimeters. About how many inches long is the string?
A. 11

B. 11.8

C. 15

D. 20

Answers

Answer:

There are 2.54 centimeters to every inch.

30/2.54 is 11.8

The length of the string in inches in 11.8.

In order to determine the length of the string in inches, the unit of conversion of centimeters to inches have to be first determined. 1 centimeter is equivalent to 0.393701 inches.

1 cm = 0.393701 inches

The second step is to multiply the length of the string in centimeter by the unit of conversion.

Length of string x unit of conversion

30 x 0.393701

= 11.8 (to one decimal place).

Please help! I am supposed to write a recursive and an explicit function for the geometric sequence but this one is really frustrating me. Thank you!

Answers

Step-by-step explanation:

Initially, there's only 1 letter.

Tania sends the letter to 4 friends.

Each friend sends a letter to 4 more friends (4 × 4 = 16).

Each of those friends sends to 4 more friends (16 × 4 = 64).

The pattern is 1, 4, 16, 64, etc.

This is a geometric sequence. The first term is 1 and each term is 4 times the previous term.

a₁ = 1

aₙ = 4 aₙ₋₁

The explicit formula is:
