Answer:
B 16 : 24
Step-by-step explanation:
8 : 12 => when multiply by 2 = 16 : 24
Answer:
See below.
Step-by-step explanation:
f(x) = -|x + 9|
compared to
f(x) = |x|
has a graph that opens downward in an upside down V shape.
It has been moved 9 units left compared to the graph of f(x) = |x|.
It reflects over the x-axis.
Dunnow what the formula is for
combinations vs permutations
combos, the order does matter and you can repeat
permutations, the order doesn't matter and once you use something, you can't repeate it
what you do is
(number of choices)^(number of slots y ou have to fill)
in this case
number of choices is 3 (3 fllavors)
number of slots=2 since 2 toppings
3^2=9
9 choices
chocolate-carmael

P( two white) = 18/40 * 17/39 = 51/260
P( black then red) = 12/40 * 10/39 = 1/13
P( two black) = 12/40 * 11/39 = 11/130
P( white then black) = 18/40 * 12/39 = 9/65
Answer:
Step-by-step explanation:
If they are parallel, that means the slope is the same. We can then use the slope point form: y - y1 = 1/2(x - x1) which is the form in the question as well.
Given that there is a point at (4,2), the equation of the line is then
y - 2 = 1/2(x-4)
