Melody stated that the sum of a positive and a negative integer equals a negative integer or 0.

1 answer:

4 0

(a) I'd say sometimes true. 3 + -7= -4 , -5 + 3= -2 , 8+-5=3, 7+-7=0

(b) I'm not too sure about this one but I what i know is that if the positive number is higher than the negative number it will be a positive. If you are adding both a negative number and a positive number that is the same value it will be 0. And if you are adding a negative that is higher than the positive it will be a negative number.

I hope this helped a bit.. (:

Answer:

$3x+2$

Step-by-step explanation:

$6x^{2} - 11x - 10 = (2x - 5)(3x+2)$

So, $\frac{6x^{2} - 11x - 10}{2x-5} = \frac{(2x-5)(3x+2)}{2x-5}$

= $3x + 2$

Hope this helps :)

3x - 4y = -15 ; 4x +3y =5

Kipish [7]

Using elimination method to find y
3x - 4y = -15 (multiply 4)
4x + 3y = 5 (multiply 3)
------------------------------------
12x - 16y = -60
12x + 9y = 15
--------------------- - (substract)
-25y = -75
y = 3

Using subtitution method to find x
3x - 4y = -15
3x - 4(3) = -15
3x - 12 = -15
3x = -3
x = -1

The solution (-1,3)
