Dante wants to buy a new sound system for his room. He borrows $500 from his older sister and agrees to pay her 6% simple annual
2 answers:
Answer: $90
Step-by-step explanation:
The formula we use to find the simple interest is given by :-
, where P is the principal amount ,r is the rate of interest ( in decimal) and t is the time period ( in years).
Given : Dante borrows $500 from his older sister and agrees to pay her 6% simple annual interest.
i.e. P=$500 ; r=6%=0.06
Now, the simple interest Dante will owe at the end of 3 years will be :-
Hence, Dante will owe $90 as interest at the end of 3 years.

g(x) is basically transformed f(x). First, let's focus on f(x) graph. Notice how the graph has slope of 1 and intersect y-axis at (0,0).
Which means that our equation for f(x) is:
Now then we focus on g(x). g(x) is f(x+k). That means if f(x) = x then f(x+k) would mean substitute x = x+k in the equation.
Next, we want to find the value of k. In the slope-intercept form or y = mx+b where m = slope and b = y-intercept. Notice the g(x) graph and see that the graph intersects y-axis at (0,4). Therefore k = y-intercept = 4.
Answer
- g(x) = x+4
- Therefore the value of k is 4.
