Answer:
72.033 ft
Step-by-step explanation:
To find this, let us set up a fraction. Since 18.47 = 1 second, y = is 3.9 seconds. Let "y" be the variable.
Step 1: Switch sides
Step 2: Apply rule:
Step 3: Multiply both sides by
Step 4: Simplify
The bear can run 72.033 feet in 3.9 seconds
Answer:
Option b
Step-by-step explanation:
The following system of linear equations is shown
These are two different slope lines.
We find the cut points of both lines with the axes.
Cut with the x axis. (y = 0)
Cut with the y axis. (x = 0)
...................................................................
Cut with the x axis. (y = 0)
Cut with the y axis. (x = 0)
The solution to this system will be a point for which it is fulfilled that:
In the image, different graphs with intersections are shown.
Locate among the options, one that shows the two lines of the system of equations according to their intersections with the x and y axes.
Option b is the only one that shows the graph of the lines
Then, The point of intersection of both lines in the graph is:
(-5, 13)
Therefore the solution of the system of equations is: (-5, 13)
You can verify this by replacing the point in the relationship
Equality is satisfied
Finally the answer is the option b
