Answers
Answer 1
Answer:
Firstly, it is an arithmetic sequence.
d=-7 a1=5
a50 = 5-7*(50-1)
a50=-338
d=-7 a1=5
a50 = 5-7*(50-1)
a50=-338

range is output
(x,y)
y=mx+b aka
f(x)=somethingx
y=output
(x,range)
look at the secondn numbers
range={0,-3,-9,5,7}
arrange them in increaseing order (for nicity)
range={-9,-3,0,5,7}

Plug in 'x' into the first equation:
Plug in 'y' into the second equation to get 'x':
To get
5(3y-16)-3y = -20
15y-80-3y = -20
12y = 60
y = 5
15y-80-3y = -20
12y = 60
y = 5
