To solve this problem, let's set up an equation, letting n represent the number that you are trying to find.
n/2 - 4 = 2
To begin simplifying this equation, you must add four to both sides.
n/2 = 6
Finally, we must multiply both sides by two, in order to get rid of the denominator of the variable n.
n = 12
We know that this answer is correct because if we plug the value 12 back into the beginning equation for the variable n, it results in a true statement.
Thus, the number is 12.
Hope this helps! :)
Answer:
bn=4*(-2)^(n-1) where n is a number of searched term
Step-by-step explanation:
b1=4 b2=-8
q=b2/b1=-8/4=-2
bn=b1*q^(n-1)
bn=4*(-2)^(n-1) where n is a number of searched term
Answer:
Step-by-step explanation:
We are given the equation y+6 = 45(x+3).
On simplifying the equation we get,
y+6 = 45x + 45×3
i.e. y+6 = 45x + 135
i.e. y = 45x + 129.
Now, x = 0 gives y = 129 and y = 0 gives x = -2.867.
The general form of a straight line is given by y = mx + c, where m is the slope and c is the y-intercept.
So, on comparing, the slope of given equation is m = 45.
Plotting this straight line y = 45x + 129 on the graph gives the following figure.
The two points selected on the graph are (0,129) and (-2.867,0).
Answer:
x = 11
Step-by-step explanation:
<u>Steps as below:</u>
- 3/4 + 2/3 + 8/9 = 2 x/36
- 3*9/4*9 + 2*12/3*12 + 8*4/9*4 = 2 x/36
- 27/36 + 24/36 + 32/36 = 2 x/36
- 83/36 = 2 x/36
- 2 11/36 = 2 x/36
- x= 11
