Use the Pythagorean theorem. The Pythagorean Theorem uses the following formula:

Plug in the known values into the equation:



Subtract both sides by 36.

Square root both sides to get b by itself.


The value of x is 8.
(12x + 9y) + (-2y) - (4x - 3y)
= 12x + 9y - 2y - 4x + 3y
= 12x - 4x + 9y - 2y + 3y
= 8x + 10y
A) 8x + 10y
Answer:
1 ) y = 2x - 1
slope = 2
y intercept is (0,-1)
2) y = -1/2x + 5
slope = -0.5
y intercept = (0,5)
Step-by-step explanation:
Volume of the cone:
V = 3.14 x 3^2 x 9/3 = 84.78
Volume of half sphere on top of cone:
V = (4/3 x 3.14 x 3^3 )/2 = 56.52
Total volume = 56.52 + 84.78 = 141.3 cm^3
