Answer:
0.85c
Step-by-step explanation:
To simplify the expression, subtract like terms:
c - 0.15c
= 0.85c
So, the simplified expression is 0.85c
Step-by-step explanation:
Exponential function is given by general form 
Where a and b are constants.
say a=1 and b=2 then we can write function as :

or 
To graph this or any exponential function, we just need to find some points then join them by a curved line.
Like plug x=0, 1, 2,... into above function and find points:
plug x=1

Hence point is (1,2)
Find more points similarly then graph them to get the graph as shown below:
Answer:
A = $2,240.00
(I = A - P = $240.00)
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3%/100 = 0.03 per year.
Solving our equation:
A = 2000(1 + (0.03 × 4)) = 2240
A = $2,240.00
The total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 3% per year for 4 years is $2,240.00.
Hopefully you have a Ti-84 calculator because that's what I'm going to use.
First, input the equation on the "y =" button and graph the equation.
Then, hit "2nd, trace", or "calc". Choose the 6th option, "dy/dx". This gives you the derivative, or slope of the secant line, at any given x value.
If you just start typing numbers and hit enter, it'll find the derivative, so for part a letters i-viii, just input those numbers and press enter.
From the looks of it, the slope approaches 4 (as you from the x-values in i-iv and v-viii, the slopes approach 4). You can also check this by just inputting the x-value 7 in dy/dx or taking the derivative of the equation and plugging in 7. Hope this helps!!

Since we already have like denominators, just add the numerators and keep the denominator.
