Answer:
x = -17
Step-by-step explanation:
divide -2x by both sides then simplify

Step-by-step explanation:
5. You are asked to write an equation of the line in slope-intercept form, so you need to determine the slope of the line and the y-intercept.
You're lucky. One of the points, (0,1), has an x-coordinate of 0, so you know that the y-intercept is 1.
Use the coordinates of the points to determine the slope of the line.
slope = (difference in y-coordinates)/(difference in x-coordinates) = (10-1)/(3-0) = 9/3 = 3
The slope-intercept equation of the line is y = 3x+1

7. When x = 0, function A = 0 and function B = 3, so function B has a greater initial value.

Answer:
1131.0 m^3
Step-by-step explanation:
Let h1 represent the height of the top cone, and h2 the height of the bottom cone. The volume of a cone is given by the formula ...
V = (1/3)πr^2·h
so the volumes of both cones together will be ...
V = (1/3)πr^2·h1 + (1/3)πr^2·h2 = (1/3)πr^2·(h1 +h2)
= (1/3)π(6 m)^2(12 m + 18 m) = 360π m^3
≈ 1131.0 m^3
