The numerator of a rational number 8 ​

Answers

Answer 1

Answer:

We conclude that the numerator of a rational number 8 will be 8.

Step-by-step explanation:

We know that any number which can be written in the form p/q is called a rational number.

i.e. p/q

Where p and q are integers and q≠0.

Here:

The numerator is pThe denominator is q

Given the number

8

As number '8' can be written in the form p/q, so it is a rational number.

i.e. 8/1

Thus,

The numerator = 8The denominator = 1

Therefore, we conclude that the numerator of a rational number 8 will be 8.

Answer:  [tex]-p^2-(q+r)^2[/tex]

Work Shown:

I'm assuming your teacher wants you to factor as much as possible.

[tex]-p^2-q^2-r^2-2qr\\\\-p^2-q^2-2qr-r^2\\\\-p^2-(q^2+2qr+r^2)\\\\-p^2-(q+r)^2\\\\[/tex]

In the last step, I used the rule that [tex](a+b)^2 = a^2+2ab+b^2[/tex]

We cannot factor any further. If the first term was [tex]p^2[/tex] instead of [tex]-p^2[/tex], then we could use the difference of squares factoring rule.

PROVING A THEOREM In Exercises 7-9, write a two-column proof for the property. (See Example 3.) 7. Reflexive Property of Segment Congruence 8. Transitive Property of Angle Congruence 9. Transitive Property of Segment Congruence​

Answers

The two-column proof are properties written with reason statements.

How to write two column proofs ?

Two column proof is always written in two columns. This proof is consist of two parts, first one is the statement part which contain the exact statement of theorem and second part is reason part which consist of reason for that particular statement or equation. Both the parts are written in different columns, thus the proof is called as two-column proof.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -7x + 6

y = -10x

Step 2: Solve for x

Substitution

Substitute in y:                   -10x = -7x + 6Add 10x to both sides:      0 = 3x + 6Isolate x term:                    -6 = 3xIsolate x:                             -2 = xRewrite:                              x = -2

Step 3: Solve for y

Define equation:                    y = -10xSubstitute in x:                       y = -10(-2)Multiply:                                  y = 20

Answer:

x = -2

y = 20

Step-by-step explanation:

y = -7x + 6

y = -10x​

y = -10x

-7x + 6 = -10x

3x = -6

x = -2

y = -7x + 6

y = -7 ( -2 ) + 6

y = 14 + 6

y = 20

Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 8) would represent a height of 8 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)

Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

A sequence of transformations that maps △DEF to △D′E′F′ is a _____ followed by a ________.

Answers

Answer:

Step-by-step explanation:

△D′E′F′ is reflection of △DEF across y = - 1.

The transformation of the △DEF to △D′E′F′ is as follows; The △D′E′F′ is a reflection of △DEF across y = - 1.

What is the transformation of a graph?

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

Reflection is a mirror image of a graph about any axis.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

As per the given triangle △DEF with vertices D (1, 2) , E (2, 0) , and F (−1, 0) .

The plot of the above triangle has been plotted below,

As per the given triangle △D′E′F with vertices D′ (1, −4) , E′(2, −2) , and F′ (−1, −2) .

The plot of the above triangle has been plotted below,

It is clear that △DEF is reflected and how much is reflected can be known by making equal distance.

Since it equals apart from y = -1 thus it will be a reflection of y = -1.

Hence "The transformation of the △DEF to △D′E′F′ is as follows; The △D′E′F′ is a reflection of △DEF across y = - 1".
