Perpendicular lines have negative reciprocal slopes. All that means is " flip " the slope and change the sign.
slope = -2, or -2/1....so flip the slope...-1/2...and change the sign...1/2.
so the perpendicular slope would be 1/2.
Answer:

Step-by-step explanation:
Given


Required
Complete the equation y - 4.....
First, we need to determine the slope as follows:



The equation is then calculated as thus:

This gives:

Open bracket

Add 4 to both sides




Okay. So t is in the parenthesis of the equations and represents the number of years after 1950. In this case, the first, second, third, and the seventh tile won't work, because those numbers are too big to be applicable as years. The number of vinyls sold each year would be put behind the equal sign. If you solve it correctly, here are your answers starting from the top:
1. f(8) = 68,594
2. f(11) = 91,299
3. f(2) = 38,720
4. f(17) = 161,743
Answer:
365
Step-by-step explanation:
3+3=6+8=14-9=5+360=365
