Answer:
The answer is 42.67 cubic inches.
Step-by-step explanation:
Both the models are in the shape of a square pyramid.
The length of the sides of the base for both the models is 8 inches.
Amy’s model is 5 inches tall and Alex’s model is 3 inches tall.
The volume is given by :
So, Amy's figure volume is :
= 106.67 cubic inches
And Alex's figure volume is:
= 64 cubic inches
So, the difference between volumes is = cubic inches.
The answer is 42.67 cubic inches.

Answer: y=-13/12x-7
Step-by-step explanation:
To find the slope-intercept form, we first need to find the slope. To find the slope, you use the formula . We use the two given points to find the slope.
Now that we have our slope, we can start filling out the slope-intercept form equation.
y=mx+b
y=-13/12x+b
Since we don't know the y-intercept, we can use one of the given points and solve for b.
6=(-13/12)(-12)+b [multiply (-13/12) and -12]
6=13+b [subtract both sides by 13]
b=-7
With the y-intercept, we can complete our equation.
y=-13/12x-7
