Answer:

Step-by-step explanation:
The formula for the volume (V) of a sphere is:
V = ⁴/₃πr³
We can use this equation to calculate the radius (r).

The equation of any line is:

m is slope.
We just need to put inside of equation x=(-3) and y=5:


It follows that equation of a line is:
2^9 = 2 x 2 x2 x 2 x 2 x 2 x2 x 2 x 2 = 512
2 ^9 = 512
Answer:
Step-by-step explanation:
She added 3x and -2x, getting 5x, instead of x. She needs to pay more attention to the positive/negative signs.
