Two of the steps in the derivation of the quadratic formula
are shown below
Which operation is performed in the derivation of the
quadratic formula moving from Step 6 to Step 7?
Step 6: blanc = (x +
Step 7: 1/524 = x + more
subtracting
from both sides of the equation
squaring both sides of the equation
taking the square root of both sides of the equation
taking the square root of the discriminant

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

hi! i think the answer is 1/2 : )

i believe that the slope of the line is -5
