Answer:
Suppose that during its flight, the elevation e (in feet) of a certain airplane and its time ... since takeoff, are related by a linear equation. Consider the graph of this equation, with time represented on the horizontal axis and elevation on the vertical axis. ... Unit 3; Linear Relationships Lesson 9: Slopes Don't Have to be Positive.
Step-by-step explanation:
Answer:
Sanchez-97
Washington-117
Step-by-step explanation:
Add 4 to both sides
x - 4 < -3
x-4+4 < -3+4
x < 1
To graph this on a number line, plot an open circle at 1 on the number line. Do not fill in the open circle. Shade to the left of the open circle. The shaded region represents all x values smaller than 1.
The graph is shown below.
Answer:
18
Step-by-step explanation:
33-15=18 I belive that is the mean
Answer:
(3,1)
Step-by-step explanation:
Multiplying the second equation by 3, we get
-12x-6y=-42.
Now, adding this to the first equation, we get
-13x=-39
Therefore, x=3
plugging in x=3 to the first equation, we get that
-3+6y=3
adding 3 to both sides,
6y=6
therefore, y=1
