Answer: interest = $ 3,629.34
Step-by-step explanation:
Complete question
(Marlie will be starting college next year, federal unsubsidized student loan in the amount of $18,800 at 4.29%. She knows that during this non-payment time, interest will accrue at 4.29%. Suppose Marlie only paid the interest during her four years in school and the six-month grace period. What will she now pay in interest over the term of the loan.)
This question relates to interest over a single period of time and since it's not compounded, we use formula for simple interest to calculate the interest accrued.
Data;
P = $18,800
R = 4.29% = 0.0429
T = 4.5 years
S.I = ?
S.I = PRT
S.I = 18,800 * 0.0429 * 4.5
S.I = $3,629.34
Therefore she'll need to pay $3,629.34 as interest accrued.

Please solve the third question and answer in the comments and I will tell you if you are correct.
Step-by-step explanation:
1)Find the solution of the following system of equations; express the answer as a coordinate pair (x,y):
y = x + 3 subtract from the bottom and solve for x
y = -2x - 3
y - y = x - (-2x) + 3 - (-3)
0 = 3x + 6
-6 = 3x
-2 = x
y = x + 3 y = -2 + 3 y = 1 (-2, 1)
2)Find the solution of the following system of equations; express the
answer as a coordinate pair (x,y):
y = 2x + 1 subtract from the bottom and solve for x
y = x/2 + 4
y-y = 2x - 1/2 x +1 - 4
0 = x(2-1/2) - 3
3 = 1.5x
2 = x y = 2x + 1 y = 2(2) + 1 y = 5 (2, 5)
3) Find the solution of the following system of equations; express the
answer as a coordinate pair (x,y):
y = -3x + 6 subtract from the bottom and solve for x
y= -1/2x+1
y-y = x(-3 - (-1/2)) + (6 - 1) follow the examples above
Answer:
9
Step-by-step explanation:
The rate of change of a function f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ 3, 7 ]
f(b) = f(7) = 47 and f(a) = f(3) = 11, hence
rate of change = 
= 
= 9
