marusya05 [52]

Answer:

The 6 Lego kits can be selected from the 9 available Lego kits in 84 ways.

Step-by-step explanation:

Use combinations to solve this problem.

Combination is defined as the selection of <em>r</em> elements from <em>n</em> distinct objects irrespective of the order. The objects cannot be replaced.

There are 9 Lego kits available.

And the total number of children is 6.

That is, we need to select 6 Lego kits from the 9 available Lego kits.

6 Lego kits can be selected from the 9 available Lego kits in 9\choose 6 ways.

Solving the combination as follows:

{9\choose 6}=\frac{9!}{6!\times(9-6)!} \\=\frac{362880}{720\times6}\\ =84

Thus, there are 84 ways to select 6 Lego kits from 9 available Lego kits.

x = 200 - 150

x = 50

Help! I’ll say it’s the brainliest answer
lara [203]

Answer:

(x, y) → (x+8, y-3)

Step-by-step explanation:

You are moving the x coordinates 8 steps to the right, which is in the positive direction. This makes the change +8. This is where the x+8 comes from.

For the y coordinates, you are moving 3 down, which is in the negative direction which means it is y-3.

(You can pick one point, D, and track its movements. We can see that point D had to move 8 units to the right and 3 units down to become D'.)
