Y=0.6x+5 is the slope of a line parallel to the line -3x+5y=-10
Answer:
s = 11
Step-by-step explanation:
Given
= 
( cross- multiply )
8(s - 2) = 72 ( divide both sides by 8 )
s - 2 = 9 ( add 2 to both sides )
s = 11
3^2
Here’s the working out;
Answer:
A. 482
Step-by-step explanation:
5,784.5/12=482
Answer:
81 million
Step-by-step explanation:
A = Pe^rt
Let's break this equation down.
A is the total you will have.
P is the starting value.
R is the rate
T is the time.
Let's find the rate first.
74000000 = 70000000e^7r
Divide each side by 70mil
74000000/70000000 = e^7r
Then take the ln() of each side.
ln(74000000/70000000) = 7r
0.0556 = 7r
r = 0.0079
Now we can find how many people will be there in 2010.
A = 70,000,000e^(19 * 0.0079)
A = 81336530.2373
Now we round to the nearest million, leaving us with 81 million.
