Answer:
Step-by-step explanation:
㏒ 3+㏒(x+2)=1
㏒3(x+2)=1
3(x+2)=10^1
3x+6=10
3x=10-6=4
x=4/3
so A
3.

Answer:
The statement is true because the set of rational numbers is a subset of the set of natural numbers.
Step-by-step explanation:
We just started learning this yesterday so i'm pretty sure i'm right but, I hope it helps.
Answer:
The slope is 1/2
Step-by-step explanation:
The rate of y over the rate of x so it would be y/x. You put the equation y2-y1/x2-x1
Which would look like -3-3/-4-8= -6/-12=6/12 and then you simplify it to 1/2
