Answer:
x^2 - 3x - 28
Step-by-step explanation:
(x+4)(x-7)
x^2-7x+4x-28

Answer:
C
Step-by-step explanation:
Direct variation is a special case of first order equations; in both cases, the input is multiplied by a constant which we call the "slope" or "constant of variation." However, no direct variation equation includes a constant ("y-intercept"). So, if a given equation does have a y-intersect, that equation does not represent direct variation; if it does NOT have a y-intercept, that equation represents direct variation.
A) involves a constant term, -2; NOT direct variation
B) involves a constant term, 10; NOT direct variation
C) Here 3y = x, or y = x/3, involves no constant term, so Does represent direct variation
D) involves a constant term -3; NOT direct variation
Answer:
I think the relationship is proportional.
Step-by-step explanation:
3(-x^2y^3)^2
3(-x^4y^6)
-3x^4y^6
