Answer

95,040

Explanation
The interpretation of this expression is; the number of permutation of 5 objects out of 12.

12P5 = 12!/(12-5)!

=12!/7!
=(12×11×10×9×8×7×6×5×4×3×2×1)/(7×6×5×4×3×2×1)

=12×11×10×9×8
=95,040

Answer:

Equation: y = -3x -2

Graph: Attached below ↓↓↓↓↓

Step-by-step explanation:

The equation is y = -3x + b

We need B at this point.

Since we have a point given to us,( -2, 4)we can input the x and y

Solve:

4 = -3(-2) + b

4 = 6 + b

b = -2

So the equation we have is y = -3x -2

Let's graph the line.

We go 2 units below the x-axis, because the y-intercept is -2, and the slope is -3, so we go down 3 units, and to the right 1.

Please help! In the question you have to find whether the number is either rational or irrational.

Mnenie [13.5K]

Answer:

Square root of 30 is irrational because the answer is a non-terminating decimal.

4/7 is rational because it is a fraction.

21 divided by the square root of 4 is irrational because the result is a non-terminating decimal.

Pi is irrational because it's a non-terminating decimal.

-27 is rational because rational numbers can be positive or negative.

I hope this is correct! :-)
