16-3y because you distribute through the parenthesis frist and then you solve for your answer
The correct answer is (-2,1,2,8)
The range are the y- values
The explanation:
The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.
Hope this helped you :D
Answer/Step-by-step explanation:
The diagram of the circular track is missing, and so also its dimensions.
However, let's assume the dimensions of the circular track given is diameter (d) = 20 meters or radius (r) = 10 meters.
Since it's a circular track, the circumference of the track would give us the number of meters she runs in 1 lap.
Circumference = πd
d = 20 m (we are assuming the diameter is 20 meters)
π = 3.14
Circumference of circular track = 3.14 × 20 = 62.8 m.
This means that 1 lap = 62.8 m that she would have to run.
Therefore,
6 laps would be = 6 × 62.8 = 376.8 m
Therefore, if she completes 6 laps around the circular track that has a diameter of 20 m, she will have to run about 376.8 m.
Answer:
a(2) = 9
a(4) = 23
a(10) = 65
Step-by-step explanation:
a(2) = 2 + (2 - 1)(7)
= 2 + 1(7)
= 2 + 7
= 9
a(4) = 2 + (4 - 1)(7)
= 2 + 3(7)
= 2 + 21
= 23
a(10) = 2 + (10 - 1)(7)
= 2 + 9(7)
= 2 + 63
= 65
1/2 + 1/3 = 3/6 + 2/6 = 5/6.....so 5/6 of the total marbles are red and white.
That means 1/6 are blue. So if 6 are blue, then 1/6 of the total marbles = 6
1/6x = 6
x = 6 * 6/1
x = 36.....there are 36 total marbles
1/2 are red.....so 1/2(36) = 36/2 = 18 are red
1/3 are white......1/3(36) = 36/3 = 12 are white
and 6 are blue.
