x2 - 16 = 0 using the following steps.
Step 1:
Step 2:
Step 3:
Step 4:
x² – 16=0
(x-2)(x + 8) = 0
X-2 = 0 or x + 8
x = 2 or x = -8
Which statement is true about Judy's
method?
A. Judy made a mistake between Steps 1 and 2.
B. Judy made a mistake between Steps 2 and 3.
C. Judy made a mistake between Steps 3 and 4.
D. Judy solve the equation correctly.

I think it's D

Step-by-step explanation:

Because all of them are true

A. Judy made a mistake between Steps 1 and 2.

She did not factor x² – 16=0 correctly.

x² – 16=0 is factored as:

(x +4) (x-4) = 0

Therefore, x = -4 and x = 4

Step-by-step explanation:

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
