Try this: Principal times (1+interest rate as a decimal fraction)^(number of yrs)
In this case, Principal = $28,000; interest rate = -0.25; # of years = 1
So Decrease in value = $28,000 (0.75)^1 = $21,000.
Answer:
x = 25 and <A = 148 degrees
Step-by-step explanation:
Basically it's asking you to find the value of x for both of those equations, x must be the same for both
6x - 2 = 4x + 48
Answer:
The 100th term of the sequence is 503.
Step-by-step explanation:
Given : Sequence 8, 13, 18,23, 28,...
To find : The 100th term in the sequence ?
Solution :
Sequence 8, 13, 18,23, 28,... is the arithmetic sequence
Where, First term is a=8
The common difference is d=13-8=5
The nth term of the sequence is given by 
The 100th term is given by,




The 100th term of the sequence is 503.
Answer:
y = 1/3x + 4 1/3
Step-by-step explanation:
2x - 6y = 12
First find the slope
Solve for y
Subtract 2x
2x - 6y -2x= 12-2x
-6y = -2x+12
Divide by -6
-6y/-6 =-2x/-6 +12/-6
y = 1/3 x -2
The slope is 1/3
Parallel lines have the same slope
Using the slope intercept form y = mx+b where m is the slope and b is the y intercept
y = 1/3x +b
And substituting in the point
4 = 1/3 (-1) +b
4 = -1/3 +b
Add 1/3 to each side
4 + 1/3 = b
y = 1/3x + 4 1/3
