Answer:
Equation that represents the line passing through the point -3, -1 with a slope of 4 is

Step-by-step explanation:
Equation of line in point slope form is
-------(1)
Here

Substituting values in equation (1)

Volume of a sphere is 4/3(pi r ^3)
You were given d = 10 so r = 5
Then just plug and chug
x = 37.5 (or) 
Solution:
Given
.
Let us take BE = x and BC = 25 + x.
To determine the value of x:
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.


Do cross multiplication, we get


Subtract 30x from both sides of the equation.

Divide by 20 on both sides of the equation, we get
x = 37.5 (or) 
Hence the value of x is 37.5 or
.
