Answer:
Find the "zeros" and plug in points
Step-by-step explanation:
You can tell this graph is a parabola.
We can find the "zeros" of the graph to help us.
Find the zeros:
2x-1=0
2x=1
x=0.5
2x-5=0
2x=5
x=2.5
We can substitute values into f(x)=(2x-1)(2x-5) to graph.
You should get (1.5,-4) to be the vertex.

Cost of a scarf = s
cost of a hat = h
4s + 6h = 52 --------------eqn(1)
2h = s + 1 ----------------eqn(2)
Solving the equations, we get s = $7
Answer is D
-20
Explanation:
(

)
Eliminate the redundant parentheses, subtract the numbers which will get you, combine like terms, rearrange terms, then your solution is:
−
1
4
2
−6
−6
Figure that problem out then you will get -20.
