Answer:
B
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos30° =
, then
cos30° =
=
=
( cross- multiply )
2x = 20
( divide both sides by 2 )
x = 10
→ B
This is a problem of fundamental counting principle. In a
sequence of events, the total possible number of ways all events can performed
is the product of the possible number of ways each individual event can be
performed. So here there is one car in each place so there 4 possible
cars to get the 1st place, 3 possible car for the 2nd
place, 2 possible cars for 3rd place and 1 for the 4th
place. The 4x3x2x1 = 24 different order
Answer:
(-1, -2)
step-by-step explanation:
y = 4x + 2
2 is the y-intercept and 4 is the slope
y = -2x - 4
-4 is the y-intercept and -2 is the slope
it would look like this
the solution is (-1, -2)
