Y=mx+b
plug in the point
3=-1*-4+b
3=4+b
b=-1
y=-1x-1
What subject is this if this is math I am good at it
So,

Write in prime factored form.

Cross-cancel
Answer:
C
Step-by-step explanation:
Calculate the values of both r and s, that is
= 7 ( multiply both sides by 2 )
5 + r = 14 ( subtract 5 from both sides )
r = 9
and
= 3 ( multiply both sides by 2 )
3 + s = 6 ( subtract 3 from both sides )
s = 3
Hence
=
= 6 → C
