Remember
ou can do anything to an equaiotn as long as you do it to both sides
try to isolate variable and get 1 of it
-6+5b=6b-7
subtract 5b from both sides
-6=b-7
add 7
1=b
A Their checking accounts typically cost less than traditional bank accounts
Undo what has been done to the variable. That means to do the opposite done to the variable.
5x-4=-19
+4=+4
5x=-15
5 is being multiplied to the variable so you divide it from both sides.
x=-3
Rate of change is slope
So change in y/change in x
150/3=50
Answer:
1
Step-by-step explanation:
I haven't done these in a few years but I was thinking that if you lay it out there are 3 sides being un 3D'd, plus the base. Making it 4 sides total.
None of the other options have 4 sides, or are all triangles, making 1 your answer.
Hope this helps :)
