m=slope
paralell has same slope
point (8,-2)
x=8 and y=-2 is a solution
sub those for x and y
-2=5(8)+b
-2=40+b
minus 40 both sides
-42=b
the value is -42

A small child makes 3 piles of blocks in a room. Each pile has 4 blocks. In another room, he makes 6 more piles of blocks. These piles also have 4 blocks each. To count the total number of blocks, his sister counts that there are 3 times 4, or 12 blocks, in one room and 6 times 4, or 24 blocks, in the other room for a total of 36 blocks. Using the distributive property, what is another way she could have counted the blocks?

Answer:
21 degrees
Step-by-step explanation:
Triangles have a total angle of 180 degrees.
This makes our equation:
3x+3+4x+135=180
Subtract 135 from both sides and combine like terms
7x + 3 = 45
Subtract 3 from both sides
7x = 42
Divide both sides by 7
x = 6

Final answer:
Considering the time constraints of the situation, only 2 trips can be made before the ship sinks. Therefore, only 10 people, as the boat carries 5 per trip, can reach the island alive.
Explanation:
This question is a mathematical problem that can be solved by considering the time constraints. To start, we know that the boat can carry 5 people at a time and it takes 9 minutes to go from the ship to the island and back.
This means that only 5 people can be transported to the island every 9 minutes.
However, the ship will sink in 20 minutes, so the boat will only be able to make 2 trips - one at the beginning, and the second after 9 minutes. Therefore only a total of 10 people (5 people per trip) will be able to reach the island before the ship sinks.

Answer:
Average speed, s = 0.8 m/s
Step-by-step explanation:
It is given that,
Distance travelled by a basketball, d = 4 meters
Time taken to cover that distance, t = 5 seconds
We have to find the average speed of the basketball. It is defined as the total distance covered by the basketball divided by total time taken. It can be written as :
or
Putting the values of d and t. We get :
s = 0.8 m/s
Hence, the average speed of the basketball is 0.8 m/s
