Step-by-step explanation:
Multiplication of fractions is easiest operation. Simply multiple numerator to numerator and denominator to denominator. For example,
Addition and subtraction requires that we find a common demoninator.
For example,
The common denominator is 12. So I need to muliply each fraction to get the right denominator. 4*3 = 12.
Then we add the numerators
Then we should reduce.
Division is a little trickier because we have to flip-flop the second term and then multiply. For example: 
I: 12x-5y=0
II:(x+12)^2+(y-5)^2=169
with I:
12x=5y
x=(5/12)y
-> substitute x in II:
((5/12)y+12)^2+(y-5)^2=169
(25/144)y^2+10y+144+y^2-10y+25=169
(25/144)y^2+y^2+10y-10y+144+25=169
(25/144)y^2+y^2+144+25=169
(25/144)y^2+y^2+169=169
(25/144)y^2+y^2=0
y^2=0
y=0
insert into I:
12x=0
x=0
-> only intersection is at (0,0) = option B
Answer:
The annual interest rate is 6.25%
Step-by-step explanation:
We have been given that
P = $50,000
I = $9,375
t = 3 years
r = ?
The formula for simple interest is given by
Therefore, the annual interest rate is 6.25%
Answer:
1) 5/2 or 2.5
2) 5/2 or 2.5
Step-by-step explanation:
1) 5/2 = 2.5
2) 10/4 = 5/2 = 2.5
Because the hypotenuse of both are the segments of the same line and straight lines have the same gradient for all segments
