Answer:

Step-by-step explanation:
our expression is

we are asked to simplify the expression
in order to that we first bring the like terms together
like terms are those having the same variable or same combination of variables with exactly same degrees
Hence it would be like

now we simplify the like terms



Hence

Answer:
y=(-5/2) x -7
Step-by-step explanation:
y=mx+b
m=(-5/2)
To find b:
3=(-5/2)times"x" + b
3=(-5/2)times(-4) + b
3= 10 +b; b=-7
y=(-5/2) x -7
To find the circumference of a circle that lists only as a diameter, you would do pi*d so lets say the diameter is 6, you would do pi*6 which would end up giving you 18.84. I hope this helps a bit! (:
Y<-1/2x
Y> or = -1
Because if you plug in a number then it's the only one that fits
