So,
--------------- 1
Also, 5 pounds of trail mix and 3 pounds of jelly beans cost $ 17.
So,
--------------- 2
Multiplying equation 2 by -3, we get

Now, adding equations 1 and 3, we get

Now, plug in
in equation 1 and solve for
.

Therefore, the cost for each pound of trail mix is $ 1.75 and each pound of jelly beans is $ 2.75.
Answer:
15 feet
Step-by-step explanation:
Perimeter = All outside lengths added together
We know that the shape is a square, and squares have 4 sides.

The length of one side is 15 feet.
Answer:
f(x) = -x -1
Step-by-step explanation:
f(x) = mx + b
find 2 points on the line:
A( -1 , 0)
B( 0 , -1)
Put them in the equation and fine m & b:
0=m(-1)+b
-1=m(0)+b
so b= -1
and m= -1
so f(x) = -x-1
