Answer: c
Step-by-step explanation:
A direct proportion has a formula that is written this way: y=kx
what does that mean ?
There is an image at the end to make you understand .
a direct proportion is a straight line that must go from the origin . why?
- simply beacuse it equals 0 in 0 . y=k*0=0 . so the coordinates of that point are (0,0) wich is the origin !
- a direct proportion must have a constant slope to make it go straight or it wouldn't be a straight line . i left an image to make it clear
- a diect proprtion must not have a slope of 1 . it can be 1, 2,100000 or 0.5
- its graph must be linear
Answer:
Step-by-step explanation:
I think similar aa
The slope is 40 and the y-intercept is 30.
Umm... What exactly are you asking for? I'm a bit confused about this question.
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
