Answer:
y = 3x
Step-by-step explanation:
Given line slope = m = -1/3
perpendicular line slope = - 1/m = 3
Point slope form through point 1, - 3
(y+3) = 3 ( x-1) expand and rearrange
y -3 = 3x- 3
y = 3x - 6
Hello there!
8m² - 4(7m³ + 5n²)
You wanna start by using the distributive property
=8n² - (-4)(7m³) + (-4)(5n²)
= 8n² - 28m³ - 20n²
= -28m³ - 12m²
