<span>The set of an integer is called the set Z
The set of integers number is composed by
the positive whole number {0, 1, 2, 3…}
and the negative whole number
{…-4, -3, -2, -1, 0} .We write it as follow
Z= {…- 4, -3, -2, -1, 0}U{0, 1, 2, 3…}.
If we assume that k is inside Z, so k can
be a negative integer of positive integer.
Besides the absolute value of a number
is always the positive value of this number.
Let be k<0 an integer different from zero,
so abs(k) >0, and abs(k)> k for all value of k.
For example for k= -2, and
abs(k)=abs(-2)=2> -2 (always)</span>
Answer:
8
Step-by-step explanation:
Like term is having the same variables and powers
each bolded below has the variable z other than 8 (second one)
8z, 8, 4z, -8z
You have to multiply every number!!
Example: 8 x 6 x 3 x 3 x 4
7x+2y=2
steps:
y+21=-7/2x(x-6)
y+21=-7/2x+21
y=-7/2x+21-21
y=-7/2x
7/2x+y=0
2(7/2x+y=0)
7x+2y=2
v is the correct answer hopefully that helped
