Answer:
Find the equation of the line perpendicular to x = 0 that passes through (-3,1)
Step-by-step explanation:
Using the equation, y - y1 = m(x - x1)
Since x = 0, the gradient, m = 0
Hence, y - 1 = 0
∴ y = 1
Answer:
2x^3 + 2x^2 - x - 10
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x) = x^3 + x^3 + 2x^2 - x - 10
Combine like terms.
f(x) + g(x) = 2x^3 + 2x^2 - x - 10
Since we made it clear that f(x) + g(x) = (f + g)(x)...
(f + g)(x) = 2x^3 + 2x^2 - x - 10
5<x<9. The third side can not be bigger than the sum of the other two sides, hence the less than 9. But it also has to add to 2 to be bigger than 7, so it has to be greater than 5.
