Answer:
If you actually meant f(x)=2x+3x−1 ,
then note it can be rewritten as:
f(x)=2x−2+5x−1=2+5x−1=y
At this point you can find x in terms of y (“make x the subject”):
y−2=5x−1⟹1y−2=x−15
⟹x=5y−2+1=y+3y−2
Switch variables back to x, and you have the inverse function of f:
g(x)=x+3x−2
How do you know you’ve calculated correctly? The composition of f with g should result in x — that is, evaluate f(g) and you should get the result x:
Answer:
The distance between those points is 13.
Step-by-step explanation:
1. (x2-x1) = (-2 - -7) = 5
2. (y2-y1) = (-7 - 5) = -12
3. (5)2 + (-12)2 = 25 + 144 = 169
4. √169 = 13
5. 13
it takes 3 years.formula interest =PRT/100 so its 252 =1200 times 7 times T all over 100 then multiply by 100 both sides to get 25200=8400T devide by 8400 both sides to get 3
