Step-by-step explanation:

[( {27})^{n + 2}  - 6 \times  {3}^{3n + 3} ]  \div  {9}^{n + 2}  \times  {3}^{n}  \\  \\   =  [(  {3}^{3}) ^{n + 2}  - 2 \times 3 \times  {3}^{3n + 3} ]  \div  {( {3}^{2}) }^{n + 2}  \times  {3}^{n}  \\  \\  =  [ {3} ^{3n + 6}  - 2 \times  {3}^{3n + 4} ]  \div  {{3}}^{2n + 4}  \times  {3}^{n} \\  \\  =  [ {3} ^{3n + 4}  ( {3}^{2} - 2 ) ]  \div  {{3}}^{3n + 4}   \\  \\  =  \frac{ {3} ^{3n + 4}  (9- 2 ) }{{{3}}^{3n + 4}   }  \\  \\  = 7 \\

Point P is located at (-3,5)
Naya [18.7K]

Answer:

P' (- 7, - 5 )

Step-by-step explanation:

A translation of 3 units to the left means subtractin 3 from the x- coordinate with no change to the y- coordinate, thus

P(- 3, 5 ) → (- 3 - 4, 5 ) → (- 7, 5 )

Under a reflection in the x- axis

a point (x, y ) → (x, - y ), thus

(- 7, 5 ) → P'(- 7, - 5 )

CAN SOMEONE HELP ME WITH THIS PLEASE AND THANK YOU.
svp [43]

Answer:

13/20

Step-by-step explanation:

To add fractions without the common denominator, you have to make them equal so

1/4 x 5 = 5/20

2/5 x 4 = 8/20

5/20 + 8/20 = 13/20

An arithmetic sequence has t1 = 6 and common difference 2 find t12 and s12​
Sergeeva-Olga [200]

Answer:

See below ~

Step-by-step explanation:

Finding t₁₂ :

⇒ t₁₂ = t₁ + 11d

⇒ t₁₂ = 6 + 11(2)

⇒ t₁₂ = 6 + 22

⇒ t₁₂ = 28

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

Finding S₁₂ :

⇒ S₁₂ = 12/2 × 2t₁ + (12 - 1)d

⇒ S₁₂ = 6 × 2(6) + 11(2)

⇒ S₁₂ = 6 × 12 + 22

⇒ S₁₂ = 6 × 34

⇒ S₁₂ = 204

How do I show the work where 69 miles per hours is proportional to the number of hours
riadik2000 [5.3K]
<span>1. First, label the axis on your graph, with units:

time on the x-axis, in units of hours;

distance on the y-axis, in units of miles.

2. Draw a graph of distance vs. time. Distance after the first hour = 69 miles, distance after the 2nd hour = 138 miles, etc.

3. Observe that this graph is a STRAIGHT LINE with constant slope. Therefore the relationship is PROPORTIONAL.

For every other kind of graph -- i.e. not a straight line -- the relationship is NON-PROPORTIONAL.

Hope this helps. </span>
