Answer:
Step-by-step explanation:
(1) = f(x) = 4x

(2) h(x) = x + 4
y = x + 4
Replace x with y and vice versa:
x = y + 4
And then solve for 'y':
y = x - 4

(3) h(x) = x - 4
y = x - 4
x = y - 4
y = x + 4

(4) h(x) = 2x
y = 2x
x = 2y
y = 

Answer: 6 5/8
Step-by-step explanation: Divide 53 by 8. This gets you 6 with a remainder of 5, or 5/8.
Answer:
um, I am confused on the answer options, but 3(p+5) is equivalent
Step-by-step explanation:
3p+15 is the same a 3(p+5) because in 3(p+5) we have to use the distribution property
So, it is 3p +15 here's a picture to explain it better
(3(p+45) would be too big of a number as you also use the distribution property and it would be 3p+135)
Answer:
By the end of the first year Dara will have $903.125 in his account.
Step-by-step explanation:
Since this a compounded interest formula, it means that the amount invested grows exponentially overtime. In order to calculate the total of money over a period of time we must use the following formula:
M(t) = M(0)*(1 + r/n)^(n*t)
Where M(t) is the amount of money in "t" years, M(0) is the amount invested, r is the anual interest rate, n is the compound period over a year and t is the time elapsed in years.
In this problem the amount is compounded half-yearly, this means that for every year that passes the money is compounded twice, therefore n is equal to 2. Applying the data from the problem to the formula, we have:
M(1) = 800*(1 + 0.125/2)^(2*1)
M(1) = 800*(1.0625)^(2)
M(1) = 800*(1.0625)^(2) =903.125
By the end of the first year Dara will have $903.125 in his account.
