Answer:
It is 13.56
Step-by-step explanation:
You would have to divide 40.68 by 3. 3 goes 1 time into 4 so it is 10.
The percentage of change: This is how you set it up
% change = (New old value) =
(Old value) = x 100 %
40 is the old value and 72 is is the new value
The new value is greater than the old value.
(72 - 40) /40)x 100 = 80 or 80%
the percent change from 40 to 72 represents a positive change (increases) of 80.
Answer:
(h + g)(10) = -6
Step-by-step explanation:
Step 1: Define
h(x) = 3x + 3
g(x) = -4x + 1
Step 2: Find (h + g)(x)
(h + g)(x) = 3x + 3 + -4x + 1
(h + g)(x) = -x + 4
Step 3: Substitute and Evaluate
(h + g)(10) = -10 + 4
(h + g)(10) = -6
So this equation is in exponential equation format, which is 
, with a = initial value (aka y-intercept) and b = growth/decay.
Looking at our equation, since 1 is in the a placeholder, this means that the <em>y-intercept is (0,1)</em>. Looking at our four graphs, the only graph that has (0,1) as the y-intercept is the third graph. Therefore, <u>the correct answer is the third graph.</u>
It is the one in the bottom left corner. This is because you start with the number on the right (7) and plot it on the y axis (the vertical line in the middle). Then you take the slope (3x) and view it as 3/1. Start at 7 and go up 3 and then over one. Continue this until you have a line.
