Answer:
2
Step-by-step explanation:
i am not sur but 12 5 = 2?
Answer:
x=2500
*to find the mean of a set of numbers you need to add all the numbers and then divide by how many numbers are in the set*
So the equation will be
(700+1200+2000+x)
——————————— = 1600
4
Okay then add those numbers together
3900 + x
————— = 1600
4
Then you need to times 4 on both sides to get rid of the denominator of 4
- The equation is:
3900 + x = 6400
Then you move the constant to the right by subtracting
the answer is —> x = 2500
The time taken by the object to reach the ground is (app.)
Explanation:
The given function is
To graph the function in the graph, let us substitute the values for t to find the value of d.
t d
0 45
1 29
2 -19
3 -99
4 -211
5 -355
These values are plotted in the graph which is attached below:
To determine the time it takes the object to reach the ground, let us substitute in the function , we get,
The value of t cannot be negative.
Thus, (app.)
Thus, the time taken by the object to reach the ground is (app.)
<span>Simplifying
3x + -3y = 27
Solving
3x + -3y = 27
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
3x + -3y + 3y = 27 + 3y
Combine like terms: -3y + 3y = 0
3x + 0 = 27 + 3y
3x = 27 + 3y
Divide each side by '3'.
x = 9 + y
Simplifying
x = 9 + y
