Mathematics

Answer:

Step-by-step explanation:

Comment

You are going from a very small number (like - 100000) to a very large number (like + 100000).

But neither of those could be the answer. They are either not small enough or not large enough. The domain must look like this.

- ∞ < x < ∞

Answer: So the domain is all the real numbers.

-7x - 2y = 19<br> 4x + y = -12<br> Solve the system
nalin [4]

-7x - 2y = 19

4x + y = -12

Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)

-7x - 2y = 19

8x + 2y = -76

Add equations together

x = -52

Plug x value into an equation

4(-52) + y = -12

Solve for y

-208 + y = -12

y = 196

Hope this helps! ;)

<u><em>Answer:</em></u>

He read 1/3 of the book on the second day

He didn't finish the book in two days.

<u><em>Step-by-step explanation:</em></u>

Lets find 3/5 of 5/9

If we said, find 3/5 of x, the answer would be 3/5x.

3/5*x = 3/5x

In the same way, \frac{3}{5} *\frac{5}{9} = \frac{15}{45} = \frac{1}{3}

He read 1/3 of the book on the second day

Does 5/9 + 1/3 equal to 1?

1/3 = 3/9

5/9 + 3/9 = 8/9

He didn't finish the book in two days.

Hope this helps :)

Have a nice day!
