Answer:
You can manipulate both equations into y = mx + b format and end up with the same result of y = 1.2x + 1.4
Step-by-step explanation:
y + 1 = 1.2(x + 2)
y = 1.2x + 2.4 - 1
y = 1.2x + 1.4
y - 5 = 1.2(x - 3)
y = 1.2x - 3.6 + 5
y = 1.2x + 1.4
So essentially, they're the same equation but in different forms.
Answer:
A) sarah = $ 937.33 ; claire = $928.00
Step-by-step explanation:
<h2><u>Sarah - Compound interest </u></h2>
compund interest formula :
A = P ( 1 + r/100) ^ n
A is the amount invested
P is the principle
r is the rate of interest
n is the number of years
A = 800 * ( 1 + 2 /100) ^8
=937.33
Sarah has $ 937.33
<h2><u>Claire - Simple interest </u></h2>
simple interest formula :
= PRT / 100
P is the principle
R is the rate
T is the number of years
= 800*2*8 /100
=128
128 + 800 = 928
claire has $ 928
