Answer:
a²(b² - 2b) = a²b² - 2a²b
- a²(b² - 2b) is odd but -2a²b is the even number
=> a²b² must be the odd (because an odd number minus an even number equals an odd number)
=> a and b are odd (proven)
The two equations that are equivalent to given equation 6x + 2y = 8 are 3x + y = 4 and 12x + 4y = 16
<em><u>
Solution:</u></em>
Given that we have to write two equations in standard form that is equivalent to 6x + 2y = 8
The standard form of an equation is Ax + By = C. In this kind of equation, x and y are variables and A, B, and C are integers
<em><u>Given equation is:</u></em>
6x + 2y = 8
Taking 2 as common term,
2(3x + y) = 8
3x + y = 4
Thus the above equation 3x + y = 4 is equivalent to given equation
Any equation that is a multiple of given equation 6x + 2y = 8 would be equivalent.
Multiply 6x + 2y = 8 by 2
[ note that you can multiply by any term like 0.5, 3, 3.5 and so on. Here we choose 2 to multiply ]
2(6x + 2y = 8) ⇒ 12x + 4y = 16
Thus the two equations that are equivalent to given equation are 3x + y = 4 and 12x + 4y = 16
Answer:
The fourth option, 5x + 11y
Given:
(7x + 8y) - (2x - 3y)
Distribute the negative:
7x + 8y - 2x + 3y
Reorder terms (please note you cannot always do this, but we can here):
7x - 2x + 8y + 3y
Combine like terms:
5x + 11y
Answer:
5x + 11y
