Ricardo has <u>16</u><u> golf balls</u>, to begin with. He started out with 16, and lost 6, 16 - 6 = 10. He bought 12 golf balls, 10 + 12 = 22. He lost 4 golf balls, 22 - 4 = 18. So in the end, he has 18.
For this case we have the following linear equation:

The intersection with the x axis occurs when the value of y is equal to zero.
We then have to replace y = 0 in the equation:

Rewriting:

Clearing x we have:
Answer:
The x-intercept of the equation whose line is 3x + 10y = 36 is:
x = 12
Answer:
y = -
x + 
Step-by-step explanation:
The angle between the tangent and the radius at point P is 90°
Calculate the slope of the radius m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (8, 15)
m =
= 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= -
, thus
y = -
x + b ← is the partial equation
To find b substitute (8, 15) into the partial equation
15 = -
+ b ⇒ b = 15 +
= 
y = -
x +
← equation of tangent
