Answers:
The number 0 goes in the first blank for f(x)
The number 6 goes in the second blank for g(x)
----------------------------------------------------------------------------------
Explanation:
As x gets larger and larger, the expression (4/5)^x will get smaller and smaller. What's going on is that we are repeatedly multiplying (4/5) with itself over and over if we assume x is some whole number. For example, if x = 100, then we'll have 100 copies of (4/5) multiplied out. Each time we multiply by (4/5), the result gets smaller.
The results will approach 0 but not actually get there. So this is why f(x) has the horizontal asymptote y = 0. The function values f(x) will essentially be the set of positive y values, in other words, y > 0. This covers the range for f(x). To get the range of g(x), we add 6 to the range of f(x). This is because everything on g(x) is a vertical shift upward of 6 units.
Your question can be reworded as
? X 3 = 20.
All you do is divide by 3 on both sides to isolate the x. It basically looks like a magician makes the 3 disappear and then appear on the other side.
Tadah! We have mathmagically found the answer.
The answer is
in fraction form or
in decimal form.
Answer:
Cost of one candy = 80 L.L.
Step-by-step explanation:
Let "x" represent cost of a candy
Cost of 12 candies = 12x
Cost of a chocolate bar = 1,250 L.L.
Total cost = 2,210 L.L.
The following equation represents the scenario given:
1,250 + 12x = 2,210
Solve for x (cost of a candy)
1,250 + 12x - 1,250 = 2,210 - 1,250 (subtraction property of equality)
12x = 960
Divide both sides by 12
12x/12 = 960/12 (division property of equality)
x = 80
Cost of one candy = x = 80 L.L.
Return rate, r = 3% = 0.03
x = initial investment
b = final balance
After 1 year, the balance i
b = initial investment + interest
b = x + r*x = (1 + r)*x
Because r = 0.03,
b = 1.03x (after 1 year)
Answer:
a. f(n)=3(to the power of n)+1
n is the number of days, day one being when the student sent it to 3 others
the plus one is the one student
