x = 3

y = 10*3 + 2
y = 30+2

You would plug in 3 for x, which gives you y = 10(3) + 2, and then you would use PEMDAS, which means you multiply 10 with 3 and then add two which is 32. Therefore y would equal 32. :D :D

Rashid [163]

Answer:

The number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.

Step-by-step explanation:

In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.

The formula to compute the combinations of k items from n is given by the formula:

{n\choose k}=\frac{n!}{k!\cdot (n-k)!}

Compute the number of ways to select 37 people from 101 as follows:

{101\choose 37}=\frac{101!}{37!\cdot (101-37)!}

        =\frac{101!}{37!\times 64!}\\\\=\frac{101\times 100\times 99\times....64!}{37!\times 64!}\\\\=5397234129638871133346507775

Thus, the number of ways to select 37 people from 101 is, 5,397,234,129,638,871,133,346,507,775.

Answer:

zeros: x = 5, or (5, 0)

domain: x ≥ -4

Step-by-step explanation:

The zeros are the values of x where the graph crosses the x-axis. The graph crosses at x=5, so that is the zero.

___

The domain is the set of x-values for which the function is defined. There is no graph for x < -4, so the graph is only defined for x ≥ -4. The domain is x ≥ -4.

_____

The graph has the appearance of the graph of ...

y=\sqrt{x+4}-3

What is the closest perfect square greater than 54
Anna35 [415]

Answer:

64

Step-by-step explanation:

Perfect squares are integers multiplied by themselves.

  • 2 times 2  = 4
  • 3 times 3  = 9
  • 4 times 4  = 15

The closest perfect squares to 54 are 49 (7^2) and 64 (8^2).

49 is less than 54, so that's ruled out.

Therefore, the closest perfect square to 54 that is greater than it is 64.
