Answer:
Step-by-step explanation:
The volume v in cubic feet of a shipping box is modeled by the polynomial function V(x)=x^3-2x^2-19x+20, where X is the length of the box. To determine if x = - 2 is not a zero of the polynomial function, we would substitute x = - 2 into the polynomial function, V(x)=x^3-2x^2-19x+20. If the result is not zero, it means that x = - 2 not a zero of the polynomial function. Therefore
(-2)^3-2(-2)^2-19(-2)+20
= - 8 - 8 + 38 + 20 = 42
Since 42 is not equal to 0, then x = - 2 not a zero of the polynomial function.
Answer:
15/4
Step-by-step explanation:
Answer:
m = -1/3
Step-by-step explanation:
To get the slope of the line, we identify two points on the line and use the slope formula
We can have the points (-2,3) and (1,2)
We have the slope formula as;
m = (y2-y1)/(x2-x1)
m = (2-3)/(1 + 2) = -1/3
