Answer:
14 blue
Step-by-step explanation:
3/2 = 21/b
3b = 42
b = 42/3
b = 14
The solution is -5/4= -1 1/4
Separate your variables:

Integrating both sides gives
Answer:
$16,534.95
Step-by-step explanation:
To compute interest on loans, we use the compounded interest equation. We use the equation
where
- P is the principle or starting value
- A is the total amount after interest and a period of time
- r is the rate at which interest gathers as a decimal
- n is the number of times compounded in a year.
For this problem, we know P=$8000, r=19%=0.19, t=4 years and n=2. We substitute into the formula and simplify to find the total amount A.

A parallelogram should have 2 sets of parallel lines. Let's find the slope of line PQ and RS to test.
PQ:
(4-2)/(1-(-3))
2/4
1/2
RS:
(2-0)/(3-1)
2/2
1
Because 1 does not equal 1/2 (the slopes are different) the lines are not parallel. Thus, the figure is not a parallelogram.
