Answer:
49 over 9
Step-by-step explanation:
9x5+4 gives you the awnser
Move constant to other side
add 1
4c^2-8c=1
divide by 4 to make leading coeficient 1
c^2-2c=1/4
take 1/2 of linear coeficient and square it
-2/2=-1, (-1)^2=1
add that to both sides
c^2-2c+1=1/4+1
factor perfect squaer and add
(c-1)^2=5/4
square root both sides
c-1=+/-(√5)/2
add 1
c=1+/-(√5)/2
c=2.12 or -0.12
Yea something is not right.if y=6 then you cant solve the system because you end up with x^2-4x-1
Your answer is A. Organ systems must interact with one another.
Hope I helped :)
standard from Ax +By = C
y = 4x+10
subtract 4x from each side
-4x+y = 10
or 4x - y = -10
