6x+2=2x-2
6x+2-2=2x-2-2
6x=2x-4
6x-2x=2x-4-2x
4x=-4
4x/4= -4/4
x= -1

What is the image of point (4, 3) if the rotation is 90º ? Please and thank you.

Zielflug [23.3K]

Answer: (-3, 4)

Step-by-step explanation: Given point coordinate (4,3).

We need to rotate the given point about 90º.

In order to find the new coordinates of rotation 90°counterclockwise about the origin, we can apply rule (h, k) ---> (-k,h).

Where (h,k) are the coordinates of original image on axes and (-k,h) are the coordinates of rotated image.

In resulting coordinates of the image first swap the x and y coordinates of the original image and then make the sign opposite of each x-coordinate.

On applying rule (h, k) ---> (-k,h), we get

(4,3) ---> (-3, 4)

Martin had M dollars initially. First, Martin spent 1/3 of his money. Then Martin spent 3/4 of what was left. Finally, Martin sp

Ilya [14]

Answer:

first he had M some unknown amount

then he had 2/3 M since he spent 1/3 M

then he spent 3/4 of the (2/3 M) so he had 1/4 of the ( 2/3M)

then he spent what was left $20 so $20 = 1/4 ( 2/3 M) now solve for M

and check by doing each step and figuring how much was spent and how much left.

another method 

let us consider the left amount be Y and total now of M dollar be X

then

Y = amount of money Nartin has left

Y = X - ( 1/3 ) ( X ) - ( 3/4 ) ( X - 1/3 X ) - 20

Y = X - 1/3 X - 3/4 X + 3/12 X - 20

Y = X - 4/12 X - 9/12 X + 3/12 X - 20

Y = X - 10/12 X - 20

Y = X - 5/6 X - 20

Y = ( 1 / 6 ) ( X ) - 20

hope it helped u buddy : )
