Answer: (-5,-5) --> (-x,-y)
Step-by-step explanation:
90 degree rotation: (-y,x)
180 degree rotation: (-x,-y)
270 degree rotation: (y,-x)
(x+4) + ((x-15)+4)= 41
2x-7= 41
2x= 48
x= 24
Answer:
10
Step-by-step explanation:
The radius is the magnitude of the complex number that is the difference between any point on the circle and the center point. A suitable calculator can tell you that magnitude:
║(8+7i) - (2-i)║ = √((8-2)² +(7-(-1))²) = √(36+64) = √100 = 10

Answer:
14.4 or 15 bags
Step-by-step explanation:
The number of yards covered by x bags is ...
(3 1/2)x = 50 1/4
x = (50 1/4)/(3 1/2) = 50.25/3.5 ≈ 14.4*
We assume that bags of chips are available only in integer quantities.
The PTA will need 15 bags of wood chips to cover the wet section.
_____
* The exact answer is 14 5/14. We hope that an integer number is the desired solution, as anything more precise than that seems inappropriate in this context.
