Answer:
5y = x + 11
Step-by-step explanation:
Given parameters:
Equation of the line ;
y = -5x + 1
Coordinates = (2, -1)
Find the equation of a line perpendicular;
Solution:
A line perpendicular to y = -5x + 1 will have slope that is a negative inverse of the given one.
Equation of a straight line is expressed as;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
So, the slope of the new line perpendicular is
;
Now let us find the y-intercept of the new line;
x = -1 and y = 2
2 =
x (-1) + c
c = 2 +
=
The equation of the new line is;
y =
x +
or multiply through by 5;
5y = x + 11
Answer:
25 minutes
Step-by-step explanation:
Let the amount of time, in minutes, be x.
For Container A, we can write:
200 + 6x [since it has 200 and is being filled with 6 per minute]
For Container B, we can write:
500 - 6x [since it has 500 and is being drained with 6 per minute]
To find, we equate them and solve for x:
![200+6x=500-6x\\6x+6x=500-200\\12x=300\\x=\frac{300}{12}\\x=25](https://tex.z-dn.net/?f=200%2B6x%3D500-6x%5C%5C6x%2B6x%3D500-200%5C%5C12x%3D300%5C%5Cx%3D%5Cfrac%7B300%7D%7B12%7D%5C%5Cx%3D25)
<em>So, in 25 minutes (m), the two containers will have same amount of water</em>
2
Because -
2 x 12=12
2 x 13 = 36
2 x 42 = 84
