Agraph shows an x- and y-axis. the data line is in the shape of a "vee." the begins above the x-axis and to the left of the y-axis, extends below the x-axis to a point on the y-axis, and ascends above the x-axis to the right of the y-axis.
which statement describes the relationship between x and y?

as x increases, y decreases.
as x increases, y increases.
as x increases, y increases and then decreases.
as x increases, y decreases and then increases.

As x increases, y decreases and then increases.

Step-by-step explanation:

You can see in the graph as the x values are moving to the right (increasing), the y values go down first (decreasing), then go up (increasing). So basically you can see that as x increases, y decreases first, then starts to increase.

.5 lb

step-by-step explanation:

12 in / 6 in =2 in

.25 x 2 = .5 lb

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
