Answer:
1.14x = 2x
x = (0.12)(1.14)x
Step-by-step explanation:
We are going to express the data in an equation form:
If <em>x </em>was the number of cases there was in 2000 ⇒<em>currently there are 1.14x </em>cases of measles.
But the question also tells us that the number of cases now is also 2 times what it was in 2000.
So we have that <u>1.14x = 2x</u>
<u />
It also tells us that the number of measles back in 2000 was 12% of what it is now.
<u>x = (.12) 1.14x</u>
<u />
We can't really solve these equations since the problem doesn't give us any more information (I am assuming there was another part of the problem before this one that wasn't written here).
Answer:
OPTION C
Step-by-step explanation:
Given: 
This can be rewritten as: 
Also, since 

We know that 

Hence, Option C would the answer.
Y - y₁ = m(x - x₁)
y - 3 = 4(22 - 2)
y - 3 = 4(20)
y - 3 = 80
+ 3 + 3
y = 83
Answer:
- geometric sequence with initial value 20 and common ratio 1/2
- average rate of change on [1, 3] = -7.5
Step-by-step explanation:
(a) The given points have sequential values of x and values of y that are each 1/2 the value before. The common ratio tells us the sequence is a geometric sequence.
(b) The first given point is (2, 10), so extrapolating backward, we determine the previous point to be ...
... (2-1, 10/(1/2)) = (1, 20)
Thus, we have enough information to determine the average slope between n=1 and n=3.
... (difference in y)/(difference in n) = (5 -20)/(3 -1) = -15/2 = -7.5
