Answer:
y = 2x - 3
Step-by-step explanation:
The y-intercept is -3 because that is where the line hits the y-axis.
The slope is 2 because from 1 point the the next, you go up 2 right 1.
Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h

<h3>What is compound interest?</h3>
The term compound interest has to do with an interest that is charged in both the principal and the interest.
In this case, the amount that was borrowed is $36,000 - $3000 = $33,000. Using the formula;
A = P(1 + r/n)^nt
P = $33,000
r = 4.2%
n = 52
t = 5 years
A = 33,000(1 + 0.042/52)^(52 * 5)
A = $40,708
Total amount paid = $40,708 + $3000 = $43,708
