For this case we have the following expressions:
So:
Indicates all values less than or equal to -2.
That is, from -∞ to -2.
Indicates all values greater than or equal to 0.
That is, from 0 to ∞.
The "or" means that they do not intersect. So, the correct graph is option A.
Answer:
Option A
Answer:
He's descending at a pace of 2.3 meters per minute.
Step-by-step explanation:
This is because the equation shows us the slope or the speed he's going at.
A= -2.3t - 7
A= Altitude
-2.3 = Slope
- 7 is his starting altitude in meters
But every minute, t, he is going down 2.3 meters. It's easier to think about if you consider, A = y, and, t = x. Now you have the equation, y = -2.3x - 7.
And you graph it to see the progression in slope.
Answer:
Step-by-step explanation:
The equation of the line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
The points are (-6,-5) and (-4,-4), thus:
Knowing the value of the slope, the equation of the line is:
The value of b can be found using any of the points in the equation and solving for b. Let's pick the point (-6,-5):
Operating:
-5=-3+b
Solving:
b=-2
The equation of the line is:
Answer:The equation when solved for g is ---->g=P/dt - 4/t
Step-by-step explanation:
Distribute -5.5(2-6x) first
-5.5 x 2 = -11 & -5.5 x -6x =33x
=> 33x - 11
33x - 11 -2.5x
subtract common like terms
33x - 2.5x = 30.5x
Answer: 30.5x -11
