4 miles an hour you just have to divide
Given:
Year 0 = 2005 = 90,000
Year 1 = 2006 = 91,200
(91,200 - 90,000)/90,000 = 1,200/90,000 = 0.013
f(x) = 90(1.013)x
f(1) = 90(1.013)1
f(1) = 91.170
The second option, f(x) = 90(1.013)x, is the best representation of the relationship between x and f(x).
Answer:
441 and 295
Step-by-step explanation:
Let the natural number be 9x and 5x.
9x-5x=4x=196. x=49
3n+4=-5
do the opposite of adding 4. this means you have to subtract 4 from 4. whatever you do to the problem, you must do to the answer. now subtract 4 from -5.
-5-4=-9
since 4-4=0, we can take 4 out of the equation. now you have:
3n=-9
now divide -9 by 3
-9/3=-3
n=-3
hope this helps :)
Since you know Z = 2, you can plug it into:
Y = 5 · Z²
Y = 5 · (2)²
Y = 5 · 4
Y = 20
Now that you know Y = 20, you can plug it into:
X = 2 + 5Y
X = 2 + 5(20)
X = 2 + 100
X = 102
Now that you have X, plug it into "2+2X=?"
2 + 2x = ?
2 + 2(102) = ?
2 + 204 = ?
206 = ?
