3x-3 and 4x-6 are complementary angles meaning together they add up to 180°. Set them equal to each other. So you get 3x-3=4x-6 now simplify this. Now you have x=3 and there you have it! If you plug 3 into x in both equations it works! Hope this helps!
Answer:
15
Step-by-step explanation:
subtract 12 on both sides and you get
x=27-12
x=15
The y-intercept is (0, 2). Only choices C and D will give that value. Of those, choice C is a decreasing exponential, while choice D is an increasing one (as shown in the graph).
The best selection is
D. F(x) = 2(2.1)^(2x)
A deck has 52 cards
A deck has 25 black cards.
A deck has 4 "4" cards but 2 of them are black, therefore 2 red
P(black or 4) = (25 + 2) / 52 = 27/52
