What mistake did Carl make?
Carl makes the table below to determine the number of
atoms of each element in the chemical formula 4Ca(CIO3)2
Total atoms
Element
Calcium
Chlorine
Oxygen
Calculation
1x4
1x2
3x2
He did not multiply the calcium atoms by the subscript 2
He did not add the coefficient 4 to the chlorine and oxygen
atoms,
He did not add the subscript 2 to the calcium atoms.
He did not multiply the chlorine and oxygen atoms by the
coefficient 4.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

most likely linear (proportionate)
