The coordinated of the preimage would be :
x = x cos θ + y sin θ
y = x sin θ + y cos θ
where
x = -4
y = 7
θ = -90
hope this helps

Answer:
The company earns $6000 more in July than June.
Step-by-step explanation:
In June your company had a loss of 1,200 after making some changes your company profited 4,800 for the month of July.
Now, we have to calculate the earning of the month of July with respect to the month of June.
The earning in June month was - $1200 and in July was + $4800.
Therefore, the company earns $[4800 - (- 1200)] = $6000 more in July than June. (Answer)
(x+3y) (x-3y) = x^2 9y^2
(x-y) (x+3y) = x^2+2xy-3y^2
(xy+9y+2) (xy-3) = x^2 y^2 +9xy^2-xy-27y-6
(x^2+3xy-2) ( xy+3) = x^3 y+3x^2 y^2 +7xy-6
(2xy+x+y) (3xy^2-y) = 6x^2 y^3 +3x^2 y^2 +xy^2-2xy^2-xy-y^2
(xy+3x+2) ( xy-9) = x^2 y^2 +3x^2 y -7xy-27x-18
