Step-by-step explanation:
He stated with 15 15x and made 10 for each y=15+10
This is some simple Algebra
So it's 4x+16=-2
We subtract 16 from both sides
4x=-18
Sivide both sides by 4
X=-4.5

Answer:
a and b.
Step-by-step explanation:
I’ll explain by giving an example.
Let’s say that: a=3;b=4;c=5; => they all are consecutive -> their sum is 12.
=> if we use a) n=3 => 3*n+3=3*3+3=12 => correct.
b) n+(n+1)+(n+2)= 3+4+5=12=> correct.
c)n+2n+3n=3+6+9=18=>incorrect.
d)3n=3*3=9=>incorrect.
Answer:
6
Step-by-step explanation:
limit is defined when the limit from both side are defined and equal to f
, limit f(x)=-4-(-10)=6
f(-10)=6
, limit f(x)=(-10)+16=6
Then
, limit f(x)=6
