What type of inequality will lead to no solution?
5<-2
What is a one to one function?
What is when one x-value has only one y-value?
What does it mean to isolate the variable?
To get the variable by itself.
Solve for x: 5(x+4)=4(x+7)
x=8
solve for n: 9n-6=5n+18
n=6
what is the answer to this problem?

What is distribution?
to spread out terms equally across an expression.
4a+8=3a+10
a=2
What is 2 solutions for solving an inequality
Multiply or divide on both sides
Is this a function, one to one function, or not a function?
x: 1, 3, 1, 7, 1, 2
y: 1, 3, 4, 6, 9, 0
not a function.
solve for x: 2x-5=3
x=4
Retalling
solve for x: -2x-9=6x+15
