Which is the simplified form of ( 9c^-9 )^-3 ?

Answer:

B

Step-by-step explanation:

Let's take a look at each statement.

A: ∠1 ≅ ∠8

Angle 1 is congruent to angle 8.

If lines are parallel then angle 1 and angle 8 would be same side (consecutive) exterior angles which are supplementary and not congruent.

Therefore this statement would prove that the lines are not parallel.

B: ∠1 ≅ ∠7

Angle 1 is congruent to angle 7.

If lines are parallel then angle 1 and angle 7 would be alternate exterior angles which are congruent.

This statement proves that the lines are parallel. We have angle 1 that is at line AB and angle 7 which is at line CD. It's important that one angle is at one line and the second angle at the other line, otherwise we cannot prove that the lines are parallel.

C: ∠6 ≅ ∠8

Angle 6 is congruent to angle 8.

Angles 6 and 8 are vertical angles and they are congruent.

This statement is correct but it doesn't tell us anything about the relationship of angles at the other line, therefore it proves nothing.

D: ∠1 and ∠2 are supplementary.

Angles 1 and 2 create a linear pair, therefore they are supplementary.

This statement is also correct but again it tells us nothing about the angles at the other line so it again proves nothing.

The nth term of the Sequence: 40, 33, 26, .... is 47 - 7n.

An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same.

Here, we know nth term of the Arithmetic Sequence is

             Aₙ = A + (n - 1)D

where, A is first term and D is common difference

   A = 40 and D = 33 - 40 = -7

Now,    Aₙ = 40 + (n - 1) (-7)

            Aₙ = 40 - 7n + 7

          Aₙ = 47 - 7n

Thus, the nth term of the Sequence: 40, 33, 26, .... is 47 - 7n.

Step-by-step explanation:

Answer:

Your answer is A and B

Step-by-step explanation:

A. Has 8 by 3 by 2 = 48

B. 6 by 4 by 2 = 48

C. 4 by 4 by 4 = 64

D. 11 by 2 by 2 = 44

Answer:

See below ~

Step-by-step explanation:

Solving :

(a) Coordinates of P and Q

⇒ Equate the lines' equations

⇒ 2x² - 6x - 8 = 2x - 14

⇒ 2x² - 8x + 6 = 0

⇒ x² - 4x + 3 = 0

⇒ (x - 3)(x - 1) = 0

⇒ x = 3 and x = 1

Substitute each x-value in the any of the 2 equations :

⇒ y = 2(3) - 14

⇒ y = 6 - 14

⇒ y = -8

⇒ P = (3, -8)

⇒ y = 2(1) - 14

⇒ y = 2 - 14

⇒ y = -12

⇒ Q = (1, -12)

(b)

(i) 2x² - 6x - 8 = 0

⇒ x² - 3x - 4 = 0

⇒ (x - 4)(x + 1) = 0

⇒ x = 4 and x = -1

(ii) 2x² - 6x = -4

⇒ 2x² - 6x + 4 = 0

⇒ x² - 3x + 2 = 0

⇒ (x - 1)(x - 2) = 0

⇒ x = 1 and x = 2

(c) Line of symmetry

Finding the vertex :

⇒ Vertex = (h, k)

⇒ h = -b/2a

⇒ h = -(-6)/2(2)

⇒ h = 6/4

⇒ h = 1.5

⇒ The axis of symmetry's equation is : x = 1.5

(d)

⇒ As the mentioned function is a quadratic function, irrational values such as √2, √3, √6, etc. cannot be taken into consideration

Answers:

Domain:  [tex](-\infty, 5)[/tex]

Range:  [tex][-3, \infty)[/tex]

Both are in interval notation. There's a square bracket next to the -3, and everything else is a curved parenthesis.

===========================================================

Explanation:

The domain is the set of allowed x input values of a function. We have a hole at x = 5, so this value is not allowed in the domain. But we can use anything smaller than this. The domain as an inequality is [tex]x < 5[/tex] which is the same as writing [tex]-\infty < x < 5[/tex] and that directly translates to the interval notation of [tex](-\infty, 5)[/tex]

The curved parenthesis say "exclude this endpoint". The domain is anything between negative infinity to 5, excluding both endpoints.

----------------------

The range is the set of possible y outputs of a function.

The lowest the function goes is at y = -3. The arrow indicates it goes up forever, meaning that the range as an inequality is [tex]y \ge -3[/tex] which is the same as [tex]-3 \le y[/tex] and the same as [tex]-3 \le y < \infty[/tex]

Then that directly turns into the interval notation of [tex][-3, \infty)[/tex]

We have a square bracket at -3 to include this endpoint. We can't ever reach infinity, so we of course can't include this endpoint. Always use parenthesis for either infinity.

Step-by-step explanation:

[tex]3(r+1)+2 > -7[/tex]

Use the distributive property to solve 3 (r + 1).

[tex]3r+3+2 > -7 \\3r + 5 > -7[/tex]

Now, bring 5 to the right hand side of the inequality .

[tex]3r > -7-5 \\3r > -12[/tex]

Divide both sides of the inequality by 3.

[tex]r > \frac{-12}{3} \\\boxed{\bf\:r > -4 }[/tex]

Answer:

21x

Step-by-step explanation:

7x is one term. With parenthesis, you have to multiply whatever is on the outside, inside. So that's 3*7x, or 21x.

Hope this helps!

Hey there!

3(7x)

= 3 * 7x

= 7x * 3

= 7x + 7x + 7x

= 14x + 7x

= 21x

Therefore, the answer should be: 21x

Answer:

The fraction of the rebounds the rest of the team get was 13/72 (13 out of the 72 total)

Step-by-step explanation:

Jacob gets 4/9

Adam gets 3/8

Since the given fraction provided doesn't have common denominator we would need to do thos first...

4/9 x 8/8 = 32/72

3/8 x 9/9 = 27/72

combining Adam and Jacob rebounds...

32/72 + 27/72 = 59/72

so the remaining, uncounted rebounds are...

72 - 59 = 13

The SECA taxes for the income $57000 will be $7068.

SECA stands for Self Employed Contributions Act. These taxes are computed from the net earnings, which in this case is $57000.

The basic rate for SECA taxes is 6.2% for employeer and 6.2% for employee. In the case of people who are self employed, the taxes are double, because they are employee and employeer at the same time.

So, Doug have to pay 12.4% taxes, which is equivalent to:

[tex]\rm SECA=57000\times 12.4\%= $7067[/tex]
