Answer: y=4x+12
Step-by-step explanation:
a parallel line has the same slope, so the slope remains 4
use point slope formula to write the equation

The area of one of the triangular lateral faces is

You're told that the slant height, which is the same as the height of the triangular face, is 9.8, so you have

where

is the length of the base of the triangle, which is also the same as the side length of the base of the pyramid. So
<span>Divide $380 by 20 and then multiply the result by 7. Its really not hard I promise I basically just gave you the answer</span>
Answer:
Step-by-step explanation:
A. (x, y) is not an equation.
B. 2 + 7 = 9 Not a linear equation, as there is no variable.
C. 3x + 5 = 20 This is a linear equation.
D. y = 2x + 1 This is a linear equation.
