Answer:
6 mph
Step-by-step explanation:
Difference in distance
= 15 - 12
= 3 mi
time taken
= 30 mins
= 1/2 hour
Speed
= 3 ÷ 1/2
= 6 mph
The linear equations that pass through the point (2, 9) are lines A and D.
<h3>
Which lines go through the point (2, 9)?</h3>
Here we have the 4 linear equations:
- Line A: y = 4x + 1
- Line B: y + 2x = 8
- Line C: y = 9 − 2x
- Line D: y − 3x = 3
To see which lines go through the point (2, 9), we need to replace x by 2 and y by 9 in all of these equations, and see which ones are true.
A) y = 4x + 1
9 = 4*2 + 1
9 = 9
This is true, so line A passes through (2, 9)
B) y + 2x = 8
9 + 2*2 = 8
13 = 8
This is false.
C) y = 9 − 2x
9 = 9 - 2*2
9 = 5
This is false
D) y − 3x = 3
9 - 3*2 = 3
9 - 6 = 3
3 = 3
This is true, so line D goes through (2, 9)
The correct options are lines A and D.

There are 5 total cards, 3 of them are blue.
The probability of picking a blue card is 3/5
The card is replaced and picked again so, the second pick is also a 3/5 probability.
The probability of both happening is found by multiplying the two probabilities together:
3/5 x 3/5 = 9/25
