The point A (-7,5) is reflected over the line x = -5, and then is reflected over the line x= 2. What are the coordinates of

liubo4ka [24]

Answer:

(7, 5) is the final reflection of the point.

Step-by-step explanation:

We are given point A(-7, 5) which is first reflected over the line $x= -5$ .

The minimum distance of the point A(-7, 5) from the line $x= -5$ is 2 units across the horizontal path (No change in y coordinate).

Point A lies 2 units on the left side of the line $x= -5$ .

So, its reflection will be 2 units on the right side of $x= -5$ .

Let its reflection be A' which has coordinates as (-5+2,5) i.e. (-3, 5).

Now A'(-3, 5) is reflected on the line $x=2$ .

The minimum distance of the point A'(-3, 5) from the line $x=2$ is 5 units across the horizontal path (No change in y coordinate).

Point A' lies 5 units on the left side of the line $x=2$ .

So, its reflection will be 5 units on the right side of $x=2$ .

Let its reflection be A'' which has coordinates as (2+5, 5) i.e (7, 5) is the final reflection of the point..

Please find attached image.

(7, 5) is the final reflection of the point.

Glenda checks the computer monitors made at her company for defects. It has been shown that 0.5% of the monitors are defective.

Svetllana [295]

The statement that will make this process into a binomial experiment is that "C. Glenda checks the monitors until she has 300 non-defective monitors."

Here are the following choices:
A. Glenda checks the monitors until she has 300 defective monitors.
B. Glenda checks 300 monitors and records the number that are defective.
C. Glenda checks the monitors until she has 300 non-defective monitors.
D. Glenda chooses to check 300 monitors.

-8z+12=-12 plz help asap what is the answer and what does z stand for??!?

Fofino [41]

Answer:

The answer is that z = 3

Step-by-step explanation:

Once you solve you get z = 3

-8z + 12 = -12 you subtract -12 from both sides to get rid of the positive 12

-12 = -12

__________

-8z = -24

__ __ divide -8 both sides

-8 -8 two negatives equal a positive

z = 3
