What transformation rule would represent a shift of 3 units to the left 4 units down?
Llana [10]

Given:

Shift of 3 units to the left 4 units down.

To find:

The transformation rule.

Solution:

The rule of transformation is

(x,y)\to (x+a,y+b)          ...(i)

Here, a<0 if the figure shifts a units left and a>0 if the figure shifts a units right.

Similarly, b<0 if the figure shifts b units down and b>0 if the figure shifts b units up.

If a transformation represents shift of 3 units to the left 4 units down, then a=-3 and b=-4.

Putting a=-3 and b=-4 (i), we get

(x,y)\to (x+(-3),y+(-4))

(x,y)\to (x-3,y-4)

Therefore, the correct option is B.

umka2103 [35]

Answer: 40\ beats

Step-by-step explanation:

Knowing the information provided in the exercise, you need to find the Least Common Multiple (L.C.M) in order to solve it.

You can follow these steps:

1- You must descompose 2, 5 and 8 into their prime factors:

2=2\\5=5\\8=2*2*2=2^3

2- And finally, you must multiply the commons and non commons with the highest exponent:

L.C.M=2^3*5=40

Therefore, the answer is: 40\ beats
