Judy solved the quadratic equation
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:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
