Set equal to each other since both equal 90

5x-6y=-10x-6y
add 6y to both sides
5x=-10x
x=0

5(0)-6y=-90
-6y=90
divide by -6
y=-15

(x,y)
(0,-15)

Answer:

13/20 of her money was spent.

Step-by-step explanation:

To find the answer you have to add these two fractions together, and to do that you must find a common denominator.

For this problem I chose to use 20 for the denominator since it is the smallest number that both 4 and 5 have in common.

Keep in mind that, whatever you do to the denominator, you must also do to the numerator, so if you multiply 5 by 4, you must also multiply 2 by 4.

5/20 + 8/20 = 13/20

Given:

The point is (6,2).

To find:

The image of given point after rotation of 270 degrees.

Solution:

Let the given point be P(6,2).

Rotation of 270 degrees means the figure is rotated 270 degrees counterclockwise about the origin. So, the rule of rotation is

$(x,y)\to (y,-x)$

Using this rule, we get

$P(6,2)\to P'(2,-6)$

Therefore, the image of given point is (2,-6).
