Rotate triangle ABC 90° clockwise around the origin given the vertices A(1,3)B(-1,4)C(2,5) what are the new vertices for triangle ABC

Answers

Answer:

[tex]A' = (3,-1)[/tex]

[tex]B' = (4,1)[/tex]

[tex]C' = (5,-2)[/tex]

Step-by-step explanation:

Given

[tex]A = (1,3)[/tex]

[tex]B = (-1,4)[/tex]

[tex]C = (2,5)[/tex]

Rotation: 90 degrees clockwise

Required

Determine A'B'C'

When a point [tex]P (x,y)[/tex] is rotated 90 degrees in the clockwise direction, the new coordinates is: [tex]P' (y, -x).[/tex]

So, we have:

[tex]A = (1,3)[/tex]

[tex]B = (-1,4)[/tex]

[tex]C = (2,5)[/tex]

Becomes

[tex]A' = (3,-1)[/tex]

[tex]B' = (4,1)[/tex]

[tex]C' = (5,-2)[/tex]

Jayla is a salesperson. She sold a guitar for $96 and earned 20% commission. How much
commission did jayla earn

Answers

Answer:

$115.20

Step-by-step explanation:

Hi! We need to find 1% of 96 to multiply by 20.

96 / 100 = .96

Now we multiply by 20.

20 x .96 = 19.2.

Now, we add 19.2 to what she earned in the first place (96).

19.2 + 96 = 115.20

Hope this helps!

Solve the system by substitution.
y=-x
-2x+5y=-28

Answers

Answer:

(4,-4)

x=4

y= -4

Step-by-step explanation:

We know that y is equal to and so we can plug the y value in for x into the other equation

-2x+5(-x)= -28

Solve for x

-2x-5x= -28

-7x= -28

x=4

Now that we know that x= -4 we can plug this into one of the two starting equations and solve for y

y= -(4)

y= -4

This is how I solved it !! Hope it helped , if you got any question about any step please let me know ;)
