Answer:
They left the beach at 2:20pm
Step-by-step explanation:
if they got there at 11:50am and spent 1hr and 20min swimming that would have put them at 1:20pm you then add the 30min they played volleyball which would put you at 1:50pm you then add the 35min they built sand castles for which would put you at 2:20pm. so they left the beach at 2:20pm
90 + (5x-2) + (2x+8) = 180
90 + 5x - 2 +2x + 8 = 180
7x + 96 = 180
7x = 180 - 96
7x = 84
x = 12
m<J = 5x - 2
m<J = 5(12) - 2
m<J = 60 - 2
m<J = 58
Put 3x + 3y = 45 in slope intercept form
y = 15 - 3/3x
(-3/3x is just going to simplify to -1x though)
Perpendicular form of -1x would be 1x
So your perpendicular slope would be 1
The x - intercept of 5x - 3y = 15 is (3, 0)
The y -intercept of 5x - 3y = 15 is (0, -5)
<h3><u>Solution:</u></h3>
Given equation is 5x - 3y = 15
<em><u>To find: x - intercept and y -intercept</u></em>
The x intercept is the point where the line crosses the x axis. At this point y = 0
The y intercept is the point where the line crosses the y axis. At this point x = 0.
<em><u>Finding x - intercept:</u></em>
To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x
So put y = 0 in given equation
5x - 3(0) = 15
5x = 15
x = 3
So the x - intercept is (3, 0)
<em><u>Finding y - intercept:</u></em>
To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y
So put x = 0 in given equation
5(0) - 3y = 15
-3y = 15
y = -5
So the y - intercept is (0, -5)
