Answer:
The correct answers are
Sal walks 14 km in 4 h
Sal walks 3.5 km in 1 h
Step-by-step explanation:
Given:
Distance represented by Y axis in kilometer.
Time represented by X axis in hour,
The graph of line is showing distance walked. And the two points are (1, 3.5) and (4, 14).
In plotting of points the first coordinate is always the X coordinate that is time in hour here, and the second coordinate is always the Y coordinate that is distance in km.
Therefore, the given below two options are correct
Sal walks 14 km in 4 h
Sal walks 3.5 km in 1 h

Answer:
linear
non-linear
Step-by-step explanation:
The best way is to recognise that, if
x
=
5
is a root, then
x
−
5
=
0
, and ditto for the other two roots. So we have
x
−
5
,
x
−
i
,
x
+
i
all equalling zero. To find our polynomial, we just multiply the three terms together:
(
x
−
5
)
(
x
−
i
)
(
x
+
i
)
=
(
x
2
−
i
x
−
5
x
+
5
i
)
(
x
+
i
)
=
x
3

which simplifies to
