Answer:

i believe the answer should be y=-2x+6

Step-by-step explanation:

y=-2x+b

plug in -2 for y and 4 for x

-2=-2(4)+b

-2=-8+b

add 8 on both sides

6=b

plug in 6 for b

y=-2x+6

If someone travels 20km in 30mins, what is their speed?

scoundrel [369]

You are given a distance of 20 kilometers and time of 30 minutes. You are required to find for the speed of the travelling object. The equation for speed is distance over time. Speed is a scalar quantity. It tells you the direction of the travelling object. The solution in this problem is,

Speed = distance/time
Speed = 20 kilometers / 30 minutes
Speed = 2/3 kilometers per minute or 0.667 kilometers per minute
Therefore, the speed of the object is 0.667 km per minute.

To celebrate the first day of winter, Lin was putting stickers on some of the lockers. There are 100 lockers along one side of h

loris [4]

Answer:

24, 48, 72, 96

Step-by-step explanation:

Least Common Multiple (LCM)

It's the smallest positive number that is a multiple of two or more numbers. For example, let's find the LCM of 15 and 25:

Multiples of 15: 15,30,45,60,75,90,...

Multiples of 25: 25,50,75,100,...

Note 75 is a common multiple of both and is also the smallest possible.

Lin puts a snowflake sticker every 6 lockers and a snowman sticker every 8 lockers. To find the lockers where both stickers are places, we must find the LCM of 6 and 8:

6 = 2*3

8 = 2*2*2

Multiplying the common factors the maximum number of times it appears:

LCM = 2*2*2*3 = 24

Thus, every 24 lockers there are two stickers until Lin reaches the last 100th locker along the halfway.

The sequence of lockers is:

24, 48, 72, 96
