Answer:

T.

Step-by-step explanation:

The ordered pair (-2,-1) can also be represented by (x,y). To check the inequality we can substitute the values into the given inequality.

y>-\sqrt{x+11+1}

-1>-\sqrt{-2+11+1}

-1>-\sqrt{10}

-1>-3.1622

After substituting the values, we then have a clear view that -1 is Greater than -3.1622.

Explain how to use the distributive property to find the product 3 x 4 1/5
NikAS [45]

Answer:

12.6

Step-by-step explanation:

The answer is 12.6 and here is the explanation of using the Distributive Property. Because we are multiplying a whole number by a mixed number, we have to multiply the whole number by the whole number in the mixed number and then multiply the whole number by the fraction. In this case, we have 3 x 4 1/5. We multiply 3x4=12 first, and then we multiply 3x1/5 to get 0.6. 12+0.6=12.6. Hope it helps!
