Answer:
f(x) = 3(0.2)^x
Step-by-step explanation:
The leading coefficient is 3 as x = 0 gives f(x) = 3.
When x = 1, f(x) = 0.6. so try :
0.6 =3(1.2)^1 = 3.6 so it's not the fiirst choice.
0.6 = 3(0.2)^1 = 0.6 so its last choice.
Check when x = -1:
3(0.2)^-1
= 3/ 0.2
= 15
Answer:
Tax credits
State licensing fees
State taxes
Step-by-step explanation:
Tax credits- Usually referred to as a tax deduction. States such as California have an electric car tax credit to encourage transition from carbon-fueled cars to electric or hybrid cars.
State licensing fees-Cars are usually registered in the state in which they are purchased. As such you have to pay the state's licensing fee during car purchase.
State taxes-Different states have different sales tax charged on new, used or leased cars.
We can turn this word problem into the following equation:
x^2 + 85 = (x - 17)^2
x^2 + 85 = x^2 - 34x + 289
-85 -85
_______________________
x^2 = x^2 - 34x + 204
+34x +34x
_______________________
x^2 + 34x = x^2 + 204
-x^2 -x^2
____________________
34x = 204
Divide 34 on both sides
x = 6.
The number is 6.
