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: B (x, y, z)
<u>Step-by-step explanation:</u>
In a two-dimensional plane, a coordinate is represented as (x, y).
In a three-dimensional plane, a coordinate is represented the same as the two-dimensional plane, except we need to add the third coordinate (z).
--> (x, y, z)
F(x) = x+4
f(4) = 8, f(5) = 9
Change = 1
f(x) = 3x-7
f(-3) = -16, f(5) = 8
Change = 24/8 = 3
f(x) = 9x+1
f(-5) = -44, f(-2) = -17
Change = 27/3 = 9
f(x) = 2x+9
f(1) = 11, f(2) = 13
Change = 2
In order: f(x) = 9x+1, f(x) = 3x-7, f(x) = 2x+9, f(x) = x+4
Answer:
x=-9
Step-by-step explanation:
x+5=2(7+x)
x+5=14+2x
x-2x=14-5
-1x=9
x=-9
