Answer:

(7,-6)

x = 7, y = -6

Step-by-step explanation:

(1) 6x - 5y = 72

(2) 2x + 6y = -22

multiply equation (2) by -3

-3 (2x + 6y = -22)

-6x - 18y = 66

add equation (1) and the new equation:

6x + -6x = 0

-5y + -18y = -23y

72 + 66 = 138

---> -23y = 138

divide both sides by -23

y = -6

plug in y = -6 into equation (2):

2x + 6(-6) = -22

2x - 36 = -22

2x = 14

x = 7

Is the following statement a good definition? Why? An integer is divisible by 100 if and only if its last two digits are zeros.
nikitadnepr [17]

The given statement is An integer is divisible by 100 if and only if its last two digits are zeros.

The two conditional statements that can be made are:

1) If an integer is divisible by 100 its last two digits are zeros.

This is a true statement. If a number is divisible by 100, it means 100 must be a factor of that number. When 100 will be multiplied by the remaining factors, the number will have the last two digits zeros.

<h3>What happen when last two digit of the number are 0?</h3>

2) If the last two digits of an integer are zeros, it is divisible by 100.

This is also true. If the last two digits are zeros, this means 100 is a factor of the integer. So the number will be divisible by 100.

Therefore, the two conditional statements that are formed are both true.

So, option A is the correct answer.

Yes, it is. When the definition is separated into two conditional statements, both of the statements are true.
