Step-by-step explanation:
2(x+10)+10-4+5 = 2x + 20 +10 -4 +5
2x+31 is the final answer
The distance between the 2 points is at the point (0,3). Did I answer your question?
Answer: 29.03
Step-by-step explanation:
Answer:
Her average speed is 48 miles per hour.
Step-by-step explanation:
We solve this question using a system of equations.
The speed equation is:

In which s is the speed, d is the distance, and t is the time.
Gabriella drives her car 320 miles and averages a certain speed.
So 
Then

If the average speed has been 6 miles less she could have traveled only 280 miles in the same length of time.
So, which s - 6, d = 280.

From the first equation:



Replacing:







Her average speed is 48 miles per hour.
The solution for the given differential equation is lnlxl = 
Given,

Here,
x = vy, dx = vdy + ydv
y = ux, dy = udx + xdu
Then,

Now,
