Answer:
y - 1 = 3/2(x - 6)
Step-by-step explanation:
First, we need to find the slope of the given equation. Without a graph, the easiest way to do this is by isolating y.
2x + 3y = 18
3y = -2x + 18 (Subtract 2x from both sides)
y = -2/3x + 6 (Divide both sides by 3)
The slope is -2/3. Perpendicular lines have opposite reciprocal slopes, so a line perpendicular to this one would need to have a slope of 3/2. We're given a point for this line, so we can write the equation for it in point-slope form.
Point-Slope Form:
y - 1 = 3/2(x - 6)
If necessary, this can also be written in slope-intercept form by solving for y.
Answer:
182 miles.
Step-by-step explanation:
Given:
Two trains move between two towns.
Time taken by first train = 2 hr 48 minutes =
Change minute into hour:
60 minute = 1 hour
1 minute =
48 minutes =
Time taken by first train in hour =
Time taken by second train = 4 hr 40 minutes
Similarly, 40 minutes =
Time taken by second train in hour =
The rate of the first train is 26 mph more than that of the second train.
Question asked:
What is the distance between these towns ?
Solution:
Let speed of second train =
<u>As the speed of the first train is 26 mph more than that of the second train. </u>
Speed of first train =
As two trains move between two towns means distance traveled by both train is same.
By using :
Distance traveled by first train = Distance traveled by second train
=
Subtracting both sides by
Dividing both sides by 1.87
Speed of second train = 38.93 miles per hour
= 38.93 4.67
= 181.80 miles.
Thus, the distance between these towns is 182 miles (nearest whole number).
