Clockwise rotation 90 ° about origin
R_{90, clockwise, origin}(x,y) -> (y,-x)
J(-4,1) therefore
R_{90, clockwise, origin}J(-4,1) -> J'(1,+4)

Answer:
x=1, −8
Step-by-step explanation:
Use the quadratic formula to find the solutions.
(−b±√b²−4(ac))/2a
Substitute the values a=1 , b=7, and c=−8 into the quadratic formula and solve for x.
(−7±√7²−4⋅(1⋅−8))/2⋅1
Simplify. x=(−7±9)/2
The final answer is the combination of both solutions. x=1,−8
