Answer:
y=
x-1
Step-by-step explanation:
Slope intercept form= y=mx+b
m=slope
b=y-intercept
b=-1
m= ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
y=
x-1
Answer:
ok thanks for the warning
Step-by-step explanation:
Answer:
Omg why are you soo beautiful? I love it
Answer:
Integer 1 is x
Integer 2 is y
x + y = -31
x - y = -55
Add:
2x = -86
x = -43
Substitute:
-43 + y = -31
y = 12
Therefore, the two integers are: 12 and -43
Answer:
9 + 3 + 1 + ......... = 13.5
Step-by-step explanation:
The series 9 + 3 + 1 + is the sum of an infinite geometric sequence. The first term of the series is 9 while the common ratio is 1/3;
to obtain the common ratio we obtain the quotient of any two successive terms, 3/9 or 1/3.
The sum of an infinite geometric series with first term a and common ratio r is given by;
![S_{n}=\frac{a}{1-r}](https://tex.z-dn.net/?f=S_%7Bn%7D%3D%5Cfrac%7Ba%7D%7B1-r%7D)
Plug in the values of a and r into the formula;
![S_{n}=\frac{9}{1-\frac{1}{3} }\\\\\\S_{n}=\frac{27}{2}=13.5](https://tex.z-dn.net/?f=S_%7Bn%7D%3D%5Cfrac%7B9%7D%7B1-%5Cfrac%7B1%7D%7B3%7D%20%7D%5C%5C%5C%5C%5C%5CS_%7Bn%7D%3D%5Cfrac%7B27%7D%7B2%7D%3D13.5)
