t=
number of years
P is invested
A=amount after t

If investment interest rate is
compounded monthly
, then n = 12
If investment interest rate is
compounded quarterly
, then n = 4
If investment interest rate is
compounded semi-annually
, then n = 2
If investment interest rate is
compounded annually
, then n = 1
First, we need to make the equation given to be in the form;
y=mx + b
where m is the slope and b is the intercept
8y - 3x = -8
Add 2x to both-side of the equation
8y = 3x - 8
Divide through the equation by 8
y = 3/8 x -1
comparing the above with y =mx + b
m = 3/8
slope of parallel equations are equal
From the options given the only equation with slope 3/8 is;
y= 3/8 x + 8
The above equation of the line is parallel to 8y - 3x = -8
Answer:
p = 144/11
Step-by-step explanation:
12/11 = p/12
~Simplify
12/11 = 1/12p
~Multiply 12 to both sides
144/11 = p
Best of Luck!
One rose is 50 cents, so 2 roses cost $1 ( 50 cents x 2).
2 roses per dollar x 20 dollars = 40 total roses sold.
When they sell $20 dollars they make $6, so that means they pay 20-6 = $14 dollars for the 40 roses.
$14 / 40 roses = 0.35 per rose.
She pays 35 cents per rose.
