What is 2x+19 but dont use factors
blondinia [14]

Answer:

Step-by-step explanation:

If you are solving for the equation 2x + 19 = 0, the steps are as follows.

2x+19=0

2x = - 19 (Move the 19 over to the other side)

x = - 9 1/2 (divide both sides by 2 to get x by itself.)

Find an equation of a sphere if one of its diameters has endpoints (3, 2, 5) and (5, 6, 7). Incorrect: your answer is incorrect.
prohojiy [21]

use midpoint equation

radius = distance between midpoint and one of the endpoints.

midpoint: (3+5)/2, (2+6)/2, (5+7)/2 = (4,4,6)

equation of sphere: (x-4)^2 + (y-4)^2 + (z-6)^2 = r^2

square distance between midpoint and one of the endpoints.

r^2 = 6

Equation: (x-4)^2 + (y-4)^2 + (z-6)^2 = 6
