Here is Laila’s graph from the previous screen.

Write your own equation in the form y=mx+b that could represent Laila’s graph.

Answers

Answer:

y=-1/3x+8

Step-by-step explanation:

There is no need for any specific answers, but here is one that could logically work out. Since the graph is going left/down, it has a negative slope, so -1/3 would be reasonable. The graph doesn't cross the origin and crosses above it, so this equation must have a positive 'b' value. In this case, I chose 8. y=-1/3+8 could represent Laila's graph.

Step-by-step explanation:

1. Alternate Interior Angles are angles made and formed when two parallel or non-parallel lines are intersected by a transversal

2. Corresponding Angles are angles that are in the same position relative to lines intersected by a transversal

3. Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal

4. Using the Corresponding Angle formula, we know that angle x is equivalent to the corresponding angle above it

5. Using the Alternate Exterior Angle formula, we know that the angle y is equal to the 47* angle

6. Supplementary Angles are two angles whose measures add up to 180 degrees.

7. Using the Alternate Exterior Angle formula, we know that the angle w is equal to the 35* angle

120 blocks total

Step-by-step explanation:

All of the little cubes have side length 2" Thus, the 11" height of the box cannot be used entirely: we waste the top 1" because the five layers of little cubes reach only to 10" from the bottom.

Start at the bottom of the box. The dimensions of the bottom are 12" by 8". Along the longer side we can lay 6 blocks (which add up to 12" and are 2" wide. We can add 3 more such rows to fill the available 8" width of the box bottom. That's 6*4, or 24 blocks.

We can add 4 more 6 block by 4 block layers before we have the maximum 5 layers stacked in the box.

5 layers times 24 blocks per layer comes to 120 blocks total.
