Hello there!
8m² - 4(7m³ + 5n²)
You wanna start by using the distributive property
=8n² - (-4)(7m³) + (-4)(5n²)
= 8n² - 28m³ - 20n²
= -28m³ - 12m²
Answer:
To find the inverse equation, switch the x and y variables then solve for y.
Original equation: .
y = 100 - x²
Inverse:
x = 100 - y²
y² = 100 - x
y = + √(100 - x) or the first option
