Answer:
<h2>A. The lines are perpendicular to each other because the graph of y = –6 is a horizontal line with a slope that is undefined, and the graph of x = is a vertical line with a slope of 0.</h2>Step-by-step explanation:
The given lines are and
.
Notice that they are a horizontal and a vertical line, respectively.
If one of them is vertical and the other one is horizontal that means they are perpendicular lines. The vertical line passes through 1/6 and the horizontal line passes through -6.
Therefore, they are vertical lines intercepted at (1/6 , -6).
Additionally, vertical lines always have undefined slope, and horizontal lines always have a null slope.
The Ostrich will take 64 minutes to cover 40 miles.
Data;
To calculate the time it will take the ostrich to cover 40 miles, we have to compare it with the rate (speed).
Cross multiply both sides
simplify the value
divide both sides by the coefficient of x
From the calculations above, it would take the ostrich 64 minutes to cover 40 miles.
