X f πxf
-1 2 -2
3 1 3
-1 -2 2
0 -3 0
total =3
mean (π)=πxf ÷n
= 3÷4
= 0.75 these is not answer I thank so
I don’t know but you can go download Conects. :)
13x-2. 2•5x=10x 2•-1=-2. 10x-2+3x=13x-2
Answer:
Step-by-step explanation:
|2x-3|≤9
so -9≤2x-3≤9
add 3 to each inequality
-6≤2x≤12
divide by 2
-3≤x≤6
Use a box. Split the terms into the boxes and then multiply across. Sort of like area multiplication, only with terms.
3 5x
4y 12y 20xy
3 9 15x
