Answer:
y=2x+3
Step-by-step explanation:
The answer is A
Domain: (0, infinity)
Range: ( - infinity, infinity)
The formula of the Simple Interest is:
I=PRT
P for Principle Amount ($1200)
R for Rate (5%=

= 0.05)
T for Time in years (4 years)
I = 1200 × 0.05 × 4
= $240
Add the interest to the principle amount to check the balance
$1200 + $240 = $1440
-18 because a negative number times positive is negative.
