Need help on this question
MariettaO [177]

<u>Given:</u>

The two equations are 2x-5y=-7 and 5x-3y=11

We need to solve the equations using elimination method.

<u>Elimination method:</u>

Let us multiply the equation 2x-5y=-7 by 5, we get;

10x-25y=-35 ---------(1)

Now, multiplying the equation 5x-3y=11 by -2, we get;

-10x+6y=-22 --------(2)

Adding equations (1) and (2), we have;

\ \ \ 10x-25y=-35\\-10x+\ \ 6y=-22\\---------\\-19y=-57

      y=3

Thus, the value of y is 3.

Substituting y=3 in the equation 2x-5y=-7, we have;

2x-5(3)=-7

  2x-15=-7

          2x=8

            x=4

Thus, the value of x is 4.

Hence, the solution of the system of equations is (4,3)

Therefore, Option A is the correct answer.

What is the domain and range?
Rasek [7]

Answer:

Domain:- All real numbers

Range:-[3,infinite)

Step-by-step explanation:

In the function there's no value of x for which it is not defined thus domain is R.

Now a modulus will have always it's minimum value 0 thus minimum value of function is 0+3=3. And Max value of a modulus is infinite so infinite+3=infinite.
