Step-by-step explanation:
Let a and b be integers.
Sum means addition.
So we are trying to figure out what a+b equals.
It could result in as 0, negative, or positive.
a+b is 0 when a and b are of opposite values. Example: 5+(-5) or -5+5 is 0 because 5 and -5 are opposite values.
a+b is positive when both a and b are positive. Example 5+3=5.
a+b is positive when |a|>|b| and a is positive. Example: 5+(-3)=2 since |5|>|-3| and 5 is positive.
a+b is positive when |a|<|b| and b is positive. Example: -3+5=2 since |-3|<|5| and 5 is positive.
a+b is negative when both a and b are negative. Example: -5+(-3)=-8.
a+b is negative when |a|>|b| and a is negative. Example: -5+3=-2 since |-5|>|3| and -5 is negative.
a+b is negative when |a|<|b| and b is negative. Example: 3+(-5)=-2 since |3|<|-5| and -5 is negative.
Answer:
It would be a negative number, no matter what negative integer you put it as.
Step-by-step explanation:
For example, lets substitute -2
f(-2) = -8-4-1 = -13; a negative number
The answer is D, here’s why:
You know the slope-intercept form is y=mx+b
mx being the slope and b being the y-intercept.
y=-4/7x + 9 is already in that form.
A is not the answer because the y is supposed to be by itself.
B is not the answer because again, the y is not by itself.
C is not the answer because the y is also not by itself.
In the slope-intercept form, the y must be by itself and the slope (mx) and the y-intercept must be on the other side.
Hope this helps.
