Answer:
-7
Step-by-step explanation:
*Two negatives will cancel out and turn into addition.
-12 - (-5)
Subtract 12 from 5 and add the negative sign:
-12 + 5 =
-7
The answer would be -7

The answer is D
This is because if for every $50 he saves $5, and he has saved a total of $500, you can set up a proportion to find out how much money he has saved at that point.
The proportion is as follows:
50/5 == 500/x
x is equivalent to the amount of money he has saved
You can cross multiply to get the following equation:
50x == 2500
To isolate x, you must divide both sides by 50, giving you an answer of:
x = 50
This is the same as option D
The correct answer would be irrational because 127 itself is irrational that square root is irrational
Well in order to get a factor you have to set the 2 x seperat and the last number too.. this will give you (x )(x ) they are both negative so one sign has to be a positive and the other a negative, lets find out what can we seperate the last term to, well lets see what numbers multiplied that give you -16 when adding or subtracting it gives you -6
E.J. 4 times -4 is 16 but when adding or subtracting it give you 0
lets try this 8 and 2 wehn multiplied it gives you 16 and when adding or subtracting it gives you eitehr 10 or 6!! Wow 6 that is what you need in order to get the factors of the trinomial.... SO now our factors look like (x 2)(x 8), our last step is to find out where the signs go, well if we know that the 6 is negative then we want to make our largest number a negative, this means 8 is negative so 2 will be positive so our factors now are (x+2)(x-8)... now which of these are in your choices?? well only the (x+2) so your second option would be the answer...
Hope this helps
