Answer: x+5y=-13= (x=−5y−13)
2x-5y=-20= <u>(x=5/2y-10) </u>
Step-by-step explanation: The answers are labeled in parenthesis. According to my calculations, this is what I got. Sorry for any inconvenience.
Answer:
y= -2x+6
Step-by-step explanation:
use point slope form ----> y-y,=m(x-x,)
(the commas serve as ones)
y-4= -2(x-1)
use distributive property
y-4= -2x+2
add 4 to each side
y= -2x+6
The series is an arithmetic series with first term -10 and common difference (-2-(-10))=8. The general term a_n can be written as
a_n = -10 + 8(n-1)
or
a_n = -18+8n
The last term corresponds to
110 = -18+8n
128 = 8n
16 = n
So, the summation can be written as
