## Answer

**Answer 1**

Answer:

6 = 2 • 3

8 = 23

18 = 2 • 32

**answer 2**

Answer:

72

Step-by-step explanation:

Consider the least common multiple of 6 and 8

The multiples of 6 are: 6, 12, 18, 24, 30, 36, ...

The multiples of 8 are: 8, 16, 24, 32, 40, ......

the common multiple is 24 or 48 or 72

The multiples of 18 are: 18, 36, 54, 72, 90, ....

Because 72 is a multiple of 8 and 6 and also a multiple of 72

So the least common multiple of 6, 18, and 8 is 72.

What is the pixel of (2,-7) after shifting 4 units to the right and 3 units up?

### Answer

Answer:

(6, - 4)

Step-by-step explanation:

Shifting 4 units to the right is equivalent to adding 4 to the x coordinate

Shifting 3 units upwards is equivalent to adding 3 to the y-coordinate

(x, y) → (x + 4, y + 3) ← translation rule

For this reason

(2, - 7) → (2 + 4, - 7 + 3) → (6, - 4)

Answer: (−2,−7)→(−2+4,−7−2)=(2,−9)

Explanation: {4 units to the right: add 4 to the x-coordinate}

2 units lower: subtract 2 from the Y coordinate

A stone fell from the top of a cliff into the sea. In the air it had an average speed of 16 m/s. It had an average speed of 3 m/s in the water before hitting the seabed. The total distance from the top of the cliff to the bottom of the sea is 127 meters, and the entire fall from the stone took 12 seconds.

How long did the stone fall in the air and how long in the water?

### Answer

Answer:

Falling time of the stone in the air = 7 seconds

Time to fall into the water = 5 seconds

Step-by-step explanation:

Given in the question

Stone speed in air = 16 m/s

Speed of stone in water = 3 m/s

The total distance from the top of the cliff to the bottom of the sea is 127 m

the total time it took to reach the seabed = 12 s

Suppose the time it took to get to the water is x

then the time it took from the water surface to the seabed = 12 - x

Formula to use

Distance = speed x time total distance = first distance + second distance

127 = 16x + 3(12-x)

127 = 16x + 36 - 3x

127 - 36 = 16x - 3x

91 = 13x

x = 91/13

x = 7 seconds

12 - x = 12 - 7 = 5 seconds

Solve for y 48= 8/3y

### Answer

Answer:

j = 18

Step-by-step explanation:

To find the value of y, you need to multiply the fraction 8/3 by the reciprocal 3/8 on both sides. That means you do 48 times 3/8 to get the value of y. Once you multiply, you get 144/8, which simplifies to 18.

For the function F(x) = 1/x plotted below, what is the relative value of F(x) when the value of x is close to zero? A: A very large positive number or a very large negative number

B. A very small positive number

C. Just a really big positive number

D. Just a really big negative number

E. Either a very small positive number or a very small negative number

### Answer

Okay, think about it. If you divide by anything less than 1, your number will increase.

Same if it's negative, only now the answer is negative. So if x gets really close to 0, it's very big or a big negative number. Remember that "approaching 0" can mean both a negative and a positive side.
