Only in d. are the number related by multiplication (Multiplied by 3 each time to get the next number in the sequence).
3 x 3 =9
9 x 3 =27
27 x 3 = 81 etc.
To start take the equation and then plug in 9 for x
3x+4y=43
3(9)+4y=43
27+4y=43
Subtract 27 from each side to get all of the y's by themselves
27+4y-27=43-27
4y=16
Divide by four to get the value of one y
4y/4=16/4
y=4
Answer:
choce 3
Step-by-step explanation:
you can add n = 1,2,3,4 ....
you will receive the values as 1, 1/2, 1/4, 1/7
........

5⁰ = 1
Answer:
From the test give in the question it is obvious that there is enough evidence to show that population mean varies for vegetarian and non-vegetarian
The P-value helps affirm the null hypothesis claims,The P-value attains values relatively as large as that which exists in the sample given,if the null hypothesis is right
Step-by-step explanation:
From the question we are told that
Sample mean 
Standard deviation 
Sample size 
Sample mean 
Standard deviation 
Sample size 
Generally this is a two tailed test
therefore
Null hypothesis = 
Alternative hypothesis

<em>1. x = - 7/3 = - 2 1/3</em>
<em>2. x = -2</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em />
<em>3x + 12 = - 6x - 9</em>
<em>3x + 6x = - 12 - 9</em>
<em>9x = - 21</em>
<em>x = - 21⁽³/9</em>
<em>x = - 7/3</em>
<em>x = - 2 1/3</em>
<em />
<em>12x + 20 = 2x</em>
<em>12x - 2x = - 20</em>
<em>10x = - 20</em>
<em>x = - 20/10</em>
<em>x = - 2</em>
<em />
<em>Good luck !</em>
