Answer:

20%

Step-by-step explanation:

An equation is 14=x/100*70 or 14=(x%)*70, either one works

solve for x:

  1. 14=x/100*70
  2. 14/70=x/100 (Divide each side by 70)
  3. 1/5=x/100 (Simplify 14/70)
  4. 100/5=x (Multiply each side by 100 to isolate x)
  5. x=20 (Simplify 100/5)
  6. 20% (Rewrite as a percent)

hope this helps!!

Answer: Function h(x)

==========================================================

Explanation:

To compare the average rate of change (AROC) for the three functions, we'll use the formula

AROC = (p(a) - p(b))/(a-b)

where p(x) is any general function and [a,b] is the interval we care about. In this case, a = 2 and b = 4.

For f(x), we have
f(x) = (-5/2)*(3)^x
f(2) = (-5/2)*(3)^2
f(2) = -22.5
--------
f(x) = (-5/2)*(3)^x
f(4) = (-5/2)*(3)^4
f(4) = -202.5
--------
AROC = (f(a)-f(b))/(a-b)
AROC = (f(2)-f(4))/(2-4)
AROC = (-22.5-(-202.5))/(2-4)
AROC = -90
So we can rule out function f as the AROC here is -90 but we want the AROC to be -6

For g(x) we have
AROC = (g(a)-g(b))/(a-b)
AROC = (g(2)-g(4))/(2-4)
AROC = (-5-(-77))/(2-4)
AROC = -36
So we can rule out g(x) as well

For h(x) we have
AROC = (h(a)-h(b))/(a-b)
AROC = (h(2)-h(4))/(2-4)
AROC = (0-(-12))/(2-4)
AROC = -6
h(x) is the function that has the proper AROC we want

So that's why h(x) is the only answer

Oduvanchick [21]
First, to estimate we can round 53.82 up to 55.00. Then you can look at it like this: when you divide 100 by 20 you get 5, so 20% is one fifth of 100. Therefore, we want to find one fifth of $55. To do this, you multiply 55*1/5. When you multiply the numerators by each other and the denominators by each other, you get 55/5. When you divide the numerator and denominator by 5, you get 11/1 or $11.

Hope this helps
