Answer:
4x-5
Step-by-step explanation:
first make the equation easier 8x -1(5+4x)
then simplify with the parenthesis 8x -5-4x
then combine like terms 4x-5
there is you answer
Answer:
4x
Step-by-step explanation:
1 four inch cup and then the rest all add 0.5 in. so you would have 16 0.5 in. and 1 4 in. so 17 cups.
Answer:

Step-by-step explanation:
The two equations given represent two straight lines in 2-D graph.
The two lines will not intersect if they are parallel.
Hence the two equations will not have solution if the lines are parallel and not coincident.
The condition for 2 lines given by the equations :
ax+by+c=0
dx+ey+f=0 to be parallel but not coincident is:

here a=2 b=-3k c=-1 d=4 e=k+2 f=-5

But also:

Hence the value of k is -2/7.
