Step-by-step explanation:
<5, 2> - <2, -3> = <5 - 2, 2 - (-3)> = <3, 5>
Answer:
x = 4
Step-by-step explanation:
Given
5 - 3x = - 7 ( subtract 5 from both sides )
- 3x = - 12 ( divide both sides by - 3 )
x = 4
Answer:
1. (-8)⋅23= -184
2. (-8)⋅(-23)= 184
3. -183
4. 18(-3)= -54
5. (-18)(-3)= 54
Step-by-step explanation:
When there are 2 negative numbers in an expression then it would equal a positive number. If there is 1 negative number and 1 positive number then it would equal a negative number.
Answer:
Step-by-step explanation:
x^2 - 6x + __ = -13 + __
take half of the coefficient in ur x term, square it, and add it to both sides
so take half of -6.....which is -3......and square it....-3^2 = 9. Now add 9 to both sides.
x^2 - 6x + 9 = -13 + 9
(x - 3)^2 = - 4
