Answer:
its going to be 2&3(x+2)(x+3)
Step-by-step explanation:
Answer:
y-4=-2(x+1)
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(-4-4)/(3-(-1))
m=-8/(3+1)
m=-8/4
m=-2
y-4=-2(x-(-1))
y-4=-2(x+1)
Answer:
im pretty sure the answers are
A) 6
b) 10
Explanation:
Since m is a unit in S, then, there exists b ∈ S such that m*b = 1, where 1 is the identity. Since S is a subring of R we have that m ∈ R, and therefore b is also the multiplicative inverse of m in R. The converse isnt true.
The set of real numbers is a Ring with the standard sum and multiplication. Every real number different from 0 has a multiplicative inverse. For example, the inverse of 2 is 1/2. However, 2 is not a unit on the subring of Integers Z.
Answer:
Step-by-step explanation:
1/4y - 1/2
= 1/4y x 4 : 4 - 1/2
= y/4 - 1/2
