The answer would be A.40% because 90%-50% and 9-5=4 so your answer would be 40% because you would bring down your zero
I believe that it would be y = (13/8)x
To solve this, you use the rule where AK x KC = DK x KB. In this case, 14(3+3X) = 12(4X+1). Then you solve like it's basic algebra. Your answer is then x=5. Or in this case answer choice D.
Answer:
A.
Step-by-step explanation:
x2 - 3x - 10. = 0
x2 + 2x - 5x - 10 = 0
(x2 + 2x) (-5x - 10) = 0
x (x + 2) - 5 (x + 2) = 0
(x - 5) (x + 2) = 0
x - 5 = 0 x + 2 = 0
x = 5 or x = - 2.
