Add the two speeds together, then divide the two, this gives the average speed. Hope this was helpful!
-2-6i I believe is the answer if not let me know
Answer:
C
Step-by-step explanation:
Perpendicular lines have slopes which are the negative reciprocal of each other. To find the slope, convert 3x-5y=8 into y=mx+b form.
3x-5y=8
-5y = -3x +8
y = 3/5 x - 8/5
The slope is 3/5 so its perpendicular slope is -5/3. Write the equation of this line through the point (3,7) using point slope form. Then simplify into y=mx+b form.

Answer:
23 x + 62
Step-by-step explanation:
Simplify the following:
5 (4 x + 12) + 3 x + 2
5 (4 x + 12) = 20 x + 60:
20 x + 60 + 3 x + 2
Grouping like terms, 60 + 20 x + 3 x + 2 = (20 x + 3 x) + (60 + 2):
(20 x + 3 x) + (60 + 2)
20 x + 3 x = 23 x:
23 x + (60 + 2)
60 + 2 = 62:
Answer: 23 x + 62
Answer:
y = -2x
Step-by-step explanation:
Find the slope and y-intercept to write an equation in the form y = mx + b
Slope = - 20/10 so -2, m = -2 since the line goes down to the right
Then it crosses the y-axis at (0,0) so b = 0 [which is the y value]
Put it all together y = -2x + 0 so y = -2x
