What is the reflection image of (5, -3) across the line y = -x?

Answers

Answer 1

Answer:

Answer:

The point (5,-3) reflection image across the line $y=-x$ is (3,-5).

Step-by-step explanation:

Given : Point (5,-3)

To find : The reflection image of given point across the line $y=-x$ ?

Solution :

The reflection across the line $y=-x$ is when both the coordinated changes its sign and position.

i.e, (x,y) across y=-x line became (-y,-x)

So, The point (5,3) reflection image across the line $y=-x$ is (3,-5).

Refer the attached figure below to see the reflection.

Therefore, (5,-3)→(3,-5)

Answer 2

Answer: Over the y-axis(x, y) → (−x, y) so ( -5, -3)

I need help here please..! I took a picture of the Multi -Step equations..!

There are 8 problems in the picture. What you need is for someone to give you
some tips and solve one or two of them.
Giving you a bunch of answers and nothing else does NOT help you.

Here are my tips to you:

A). You're always trying to find the number that the unknown letter must be equal to,
in order to make the equation a true statement. That's the solution to the equation,
and the 'answer' to the problem.

B). Always do what you have to do in order to get the letter all by itself on one side.

C). Whatever you do to one side of the equation, you must do to the other side.

==========================================

Examples, from the picture:

#3: 8x - 2 = -9 + 7x What can you do to get the 'x' all alone on one side?

Subtract 7x from each side: x - 2 = -9

Add 2 to each side: x = -7
===========================================
#2: 6 = 1 - 2n + 5

Combine the 1 and the +5 on the right side: 6 = 6 - 2n

What can you do to get the 'n' all alone on one side?

Subtract 6 from each side: 0 = - 2n

Divide each side by -2 : 0 = n
===========================================
#5: 4m - 4 = 4m

Subtract 4m from each side: - 4 = 0

There is no number for 'm' that can make -4 equal to zero.
So this equation has no solution.
(That's OK. Not every equation must have a solution.)

A bill of $424 was paid with $5 bills and $2 bills. A total of 128 bills were used. Howmany of them were fives?

Answers

Answer: 56

Step-by-step explanation:

Let the number of $5 be x

Let the number of $2 be y.

Based on the information given, we can form an equation as:

x + y = 128 ........ i

5x + 2y = 424 ....... ii

Multiply equation i by 2

Multiply equation ii by 1

2x + 2y = 256 ...... iii

5x + 2y = 424 ....... iv

Subtract iii from iv

3x = 168

x = 168/3

x = 56.

Therefore, there were 56 $5 bills.

2. What is the solution to the equation? If necessary, round your answer to the nearest tenth. A. 3x^2 = 48 B. x^2 – 2 = 12
