Please help me, I will be so thankful ​
worty [1.4K]

Answer:

Step-by-step explanation:

g(-4) = 4   ,  x < -2

g(-2) = (x - 1)²     ; -2≤x< 1

        = (-2-1)²

         = (-3)²

g(-2) = 9

g(0) = (x -1)²      ;  -2 ≤ x < 1

      = (0 -1)²

       = (-1)²

       = 1

The sum of the squares of two positive integers is 185. If one integer is 3 less than the other, fine the larger integer.
kari74 [83]

Answer:

\boxed{\sf \ 11 \ }

Step-by-step explanation:

Hi,

let's note the two integers a and b

a^2+b^2=185 \ and \\\\a = b - 3

We are asked to find b

<em>replace a in the first equation</em>

   (b-3)^2+b^2=185\\\\b^2-6b+9+b^2=185\\\\ 2b^2-6b+9-185=0\\\\ 2b^2-6b-176=0\\\\ b^2-3b-88=0\\\\b^2+8b-11b-88=0\\\\b(b+8)-11(b+8)=0\\\\(b-11)(b+8)=0\\\\ b = 11 \ or \ b = -8

As b must be a positive integer, the solution is 11

Hope this helps

Integers are a subset of irrational numbers.
Paraphin [41]

Answer:

yeah

Step-by-step explanation:

The natural numbers, whole numbers, and integers are all subsets of rational numbers. In other words, an irrational number is a number that can not be written as one integer over another. It is a non-repeating, non-terminating decimal.
