I light year = 9.46 x 10¹² km

-------------------------------------------------------------------------------------
Find the number of light years
-------------------------------------------------------------------------------------

\text {Number of light years = } \dfrac{6.8 \times 10^{13}}{9.46 \times 10^{12}}

\text {Number of light years = } 7.18

-------------------------------------------------------------------------------------
Answer: The distance from Earth to the star is 7.18 light-years.

PLEASE SHOW FULL SOLUTIONS !!!!! WILL MARK BRAINLIEST FOR THE BEST ANSWER. THANK YOU AND GOD BLESS.
zhenek [66]

Answer:

a = 8

b ≠ 18

Step-by-step explanation:

y = 4x - 7

2y = ax + b

For there to be no solution, the lines (if graphed) should be parallel meaning that their slopes are equal but the y-intercepts are different

y = mx +b is the equation of a line where m is the slope and b is the y-intercept

Multiply the first equation by 2

2y = 8x - 14

2y = ax + b

So a has to equal 8

b can be anything except 14 (otherwise the lines would be the same)

exercise alone. Two methods of collecting data have been proposed. Method I: Recruit volunteers who are willing to participate.
aniked [119]

Answer:

I) If method I is used, population of generalization will include all those people who may have varying exercising habits or routines.  They may or may not have a regular excersing habit.  In his case sample is taken from a more diverse population

II) Population of generalization will include people who will have similar excersing routines and habits if method II is used since sample is choosen from a specific population

Step-by-step explanation:

past excercising habits may affect the change in intensity to a targeted excersise in different manner. So in method I a greater diversity is included and result of excersing with or without a trainer will account for greater number of variables than method II.

Zeros: x=1 (multiplicity 2) and x=-4
BARSIC [14]
Starting with x=1, subtract 1 from each side,
(x-1)=0

Our polynomial will have multiplicity of 2 for this particular zero,
(x-1)(x-1)

and do similar with the x=-4, add 4 to each side,
(x+4)=0

So our final result is: (x-1)(x-1)(x+4)

Expand out the brackets if you need this in standard form.

3x – y = 4 2x + y = 6 (2, 2) (3, 0) (–1, –7) (0, –4)
Vitek1552 [10]
The answer is 2,2

as 3*2 - 2 = 4
ans 2*2 +2 = 4 

So it satisfies both eqautions

How are problems like these solved
Flura [38]

the angles on the opposite sides of a quadrilateral touching the circumference adds up to 180 degrees

so,

(21x-2) + (38x +5) = 180

21x+38x −2+5=180

59x+3=180

59x=177

x=3
