Answer:
129
Step-by-step explanation:
(4*2^2+8*2)= 32
(3*2^2-5*2+20)=22
(7*2+30)=44
32+31+22+44=129
Answer:
5x + y - 4 = 0
Step-by-step explanation:
When we are given two points and are asked to find the equation of the line we use the two - point form.
Two - point form: .
where: and are the two points on the line.
Given the two points are: (5,21) and (-5,-29).
Substituting in the two point form:
⇒
⇒ 5x + y - 4 = 0

Isolate the m, go backwards for PEMDAS.
C = 2m + d
C (-d) = 2m + d (-d)
C - d = 2m
(C - d)/2 = 2m/2
m = (C - d)/2
m = (C - d)/2 is your answer
hope this helps
