Answer: The correct option is, It is a line joining the points whose x and y coordinates add up to 4.
Step-by-step explanation:
The given equation is, 
when we take x = 1 then
when we take x = 2 then
From this we conclude that the sum of 'x' and 'y' coordinates is always equal to 4.
Hence, the correct answer is, It is a line joining the points whose x and y coordinates add up to 4.
The best answer would be be C.20
Answer:
x=5
Step-by-step explanation:
F(x)=-3x+21,
f(x)=6 = -3x+21
6 = -3x+21
Subtract 21 from each side
6-21 = -3x+21-21
-15 = -3x
Divide each side by -3
-15/-3 = -3x/-3
5 = x
Answer:
2/-3
Step-by-step explanation:
(y1 - y2)/(x1 - x2) = (-6 - (-8))/(1 - 4) = 2/-3
The total amount of interest will be found using compound interest formula:
A=p(1-r/100)^n
A=future amount
p=principle
r=rate
n=time
From the information given:
p=$6500, r=6%, n=25 years
thus
A=6500(1+6/100)^25
A=6500(1.06)^25
A=$27,897.16
Answer: 27897.12-6500=$$21397.2
