The answer to your question is 6
If the question is supposed to be
![-7= \frac{e}{3}+14 Subtract 14 from both sides to get -21= \frac{e}{3}](https://tex.z-dn.net/?f=-7%3D%20%5Cfrac%7Be%7D%7B3%7D%2B14%0A%20%20%20Subtract%2014%20from%20both%20sides%20to%20get%20-21%3D%20%20%5Cfrac%7Be%7D%7B3%7D%20%20)
Now multiply both sides by 3 to get 3(-21)=-63=e
180 - 120 = 60
x = y = 60/2 = 30
answer
x = 30 and y = 30
Step-by-step explanation:
x² + 20 = 2x
x² − 2x + 20 = 0
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ -(-2) ± √((-2)² − 4(1)(20)) ] / 2(1)
x = [ 2 ± √(4 − 80) ] / 2
x = [ 2 ± √(-76) ] / 2
x = [ 2 ± 2i√19 ] / 2
x = 1 ± i√19
Given:
The inequality is:
![y>5x+3](https://tex.z-dn.net/?f=y%3E5x%2B3)
To find:
The y-intercept, slope and type of line (solid or dotted).
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope and b is the y-intercept.
We have,
![y>5x+3](https://tex.z-dn.net/?f=y%3E5x%2B3)
The relation equation is:
...(ii)
On comparing (i) and (ii), we get
![m=5](https://tex.z-dn.net/?f=m%3D5)
![b=3](https://tex.z-dn.net/?f=b%3D3)
It means the slope is 5 and the y-intercept is 3.
The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.
Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.
