Seth uses 17 linking cubes to make a model house. The model house is in the shape of a rectangle and is one cube high. How many
Masja [62]

Answer:

We conclude that  Seth can make the model of the house on 9 different ways.

Step-by-step explanation:

We know that Seth uses 17 linking cubes to make a model house. The model house is in the shape of a rectangle and is one cube high.  

We calculate how many different ways could Seth make the model of the house:

C_8^9=\frac{9!}{8!(9-1)!}=9

We conclude that  Seth can make the model of the house on 9 different ways.

Which answers show y + 2x &lt; 4x - 3, rewritten to isolate y, and it’s graph?
AnnyKZ [126]

Solving  y+2x < 4x-3 for y would lead to y < 2x-3. You subtract 2x from both sides of the original inequality to get to this result.

To graph y < 2x-3, you first graph y = 2x-3 which is a straight line that goes through (0,-3) and (1,-1). This line is a dashed or dotted line as solutions are not found on the boundary. The shaded region is below the dashed/dotted boundary line to indicate where the solution set is.

To summarize: the graph is a dashed line through (0,-3) and (1,-1) with the shading below the dashed line

The answer is between A and B. It will depend on how those graphs look as to which is the final answer.
