Answer:
The year is
Step-by-step explanation:
From the question we are told that
The percentage of the number of babies born out of wedlock in 1990 is k = 28%
The percentage by which the number increase per year is i = 0.6%
The percentage of of the number of babies born out of wedlock considered is a = 31%
Generally the difference in between the percentage in 1990 and the percentage considered is

=> 
=> 
Generally the number of year require for the percentage to be equal to 31% is mathematically represented as

=> 
Generally the year which the considered percentage will be attained is

=>
=>
9514 1404 393
Answer:
y = 750 -100x
Step-by-step explanation:
The initial remaining balance is 750. The balance decreases by 100 per month, so is reduced by 100x. The equation describing this is ...
y = 750 -100x
Answer:
y =-1/4x -8
Step-by-step explanation:
3x+12y=-96
Slope intercept form is y = mx +b where m is the slope and b is the y intercept
Subtract 3x from each side
3x -3x+12y=-3x-96
12y = -3x-96
Divide each side by 12
12y/12 = -3x/12 -96/12
y =-1/4x -8
This means that you have to divide 3 by 3/4. So, let's just do that
3 divided by 3/4
3 times 4/3
4
