Answer:
The equality is true,
Step-by-step explanation:
9 is greater than 3 :)
We see that (-7,4) is the intersection
therefor x=-7 and y=4 must be true for those 2 equations
another way
the slopes must be negative then positive
not A nor D
test x=-7 and y=4
B works
B is answer
Step-by-step explanation:
Diameter = 2 times the radius or
D = 2r
Solve for r and substitute 10 for D
Your answer is -2n+13
Steps:
-2(n-9)+4, multiply -2 with (n-9)
-2n+9+4, when you multiply two negatives together you get a positive number
-2n+13, combine like terms
