Answer:
A possible number of minutes is 50
Step-by-step explanation:
5 x 10 = <em>t</em>
13^2 + 2 * 13 * n + n^2 = 18^2
169 + 26n + n^2 = 324
26n + n^2 = 324 - 169
26n + n^2 = 155
n^2 + 26n - 155 = 0
(n - 5)(n + 31) = 0
n - 5 = 0
n = 5
n + 31 = 0
n = -31.....not this one because it is negative
so n = 5 <===
Hello!
If a you want to find an equation of the line that is parallel to the given line, we must know that if two lines are parallel, then their slope will <em>always</em> have to be equal.
This means that the new equation must have a slope of -1/3.
Also, you would need to substitute the given point (6, 8) into the equation with the slope: -1/3 as well. Following these steps allows you to find the equation of line.
y = -1/3x + b (6, 5)
5 = -1/3(6) + b
5 = -2 + b (add 2 to both sides)
7 = b
Therefore, the equation of the line is y = -1/3x + 7.
