Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3y + 2x = 1 into this form
Subtract 2x from both sides
3y = - 2x + 1 ( divide all terms by 3 )
y = - 
x + 
← in slope- intercept form
with slope m = - → A
Answer:
x = 3/61
Step-by-step explanation:
Hi there!
49(9x+1) = 14(x+5)
Divide both sides by 7
7(9x+1) = 2(x+5)
Open up the parentheses
63x+7 = 2x+10
Combine like terms
63x-2x = 10-7
61x = 3
Divide both sides by 61
x = 3/61
I hope this helps!

Answer:
a represent 1
and number is 11448.
Step-by-step explanation:
We know that a number is divisible by 9 if the sum of its digit is divisible by 9.
Given number aa448
sum of 4+4+8 = 16
number divisible by 9, 18 , 27,36
as we see sum of 448 is 16 , hence sum of a+a+4+4+8 should be number divisible by 9 and greater than 16 which is 18, 27,36
Let see of if sum of digits of aa448 is divisible by 18
a+a+4+4+8 = 18
2a + 16 = 18
2a = 18-16 = 2
a =2/2 = 1
Thus, number will be 11448
________________________________________
Let see of if sum of digits of aa448 is divisible by 27
a+a+4+4+8 = 27
2a = 27 - 16
2a = 11 = 2
a =11/2 = 5.5
as digit cannot be fraction of decimal, it can take value from 1 to 9 hence
sum of digits of aa448 is not divisible by 27
______________________________________________
Let see of if sum of digits of aa448 is divisible by 36
a+a+4+4+8 = 36
2a + 16 = 36
2a = 36-16 = 20
a =20/2 = 10
as digit can take value from 1 to 9 hence sum of digits of aa448 cannot be divisible by 36 or any higher number than 36 which is divisible by 9.
Thus , a represent 1
and number is 11448.
