Answer:18.3
Step-by-step explanation:
1/2(5x + 12) = 2x - 3
5/2 x + 6 = 2x - 3
5/2 x - 2x = -3 - 6 = -9
5x = 2 x -9 = -18
x = -18/5
This creates a cone! :) the formula for volume of it is 1/3 pi R^2 (h) just in case!
Answer:
y = -
x + 1
Step-by-step explanation:
The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope using the points (3, 0) and (0, 1).
Slope = 
= 
Thus, the slope of the line is -
.
Based on the graph, the y-intercept is 1.
Thus, the equation of the line is: y = -
x + 1.
