Important variables to know:
I = interest
P = principal (investment)
R = simple interest rate
T = years
Formula: I = PRT
What information do we have?
I = $960
P = $4000
T = 3 years
R = ?
Plug into formula:
960 = 4000(3)(R)
960 = 12000R
R = 960/12000
R = .08
A. $4000 + $960 = $4960. (A= P+ I)
B. 8% (.08)
Part 2: 1080 = 4000*.09*3
A = 5080 - 4960 =$420.
Answer:
D
Step-by-step explanation:
We can rule out the second and third because the y intercept in those graphs are not 1
Now lets look at the point 2,5 on graph a
y=1/2x+1
so 5=1+1 but that is false
D is the answer by elimination
Answer:
A it is linear because it has a constant rate of change

To answer the above question based on the image, the answer is <span>EBG=45; EBG is acute. EBC=100; EBC is obtuse</span>
A) x/y = 2/3
B) x + y = 105
Solving Equation A for y
A) y = 1.5x
Substituting A into B
B) x + 1.5x = 105
2.5x = 105
x = 42
y = 63
