Answer:
C: 4
Step-by-step explanation:
4x+3=6x-5
Add five to both sides
4x+8=6x
Subtract both sides by 4x
8=2x
Divide both sides by 2
X=4
Answer:
Y=4x-27
Step-by-step explanation:
Parallel lines have the same gradient therefore it's-4
Y-5/X--8 =-4
Y-5=-4(x+8)
Y-5=-4x+-32
Y=-4x-32+5
Y=4x-27
The net change would be 60%.

Answer:
x+y= the #of trees
75+85=the amount of money
Step-by-step explanation:
First, pull out a factor of

.

Notice that when

(which you can arrive at via the rational root theorem), you have

which means you can pull out a factor of

. Upon dividing you get

The rational root theorem will come in handy again, suggesting that

appears a second time as a root, which means

Now this is more readily factored without having to resort to the rational root theorem. You have

so in fact,

shows up as a root for a third time.
So, you have

Two roots are obvious,

and

(with multiplicity 3). The remaining two are given by
