Use midpoint formula:
8+2/2 ,-3+9/2
= 5,3.
The second option
Step 1 is to factor everything!
After factoring you will get:
x-5 over (x+2)(x+5) times x+4 over (x-3)(x+4)
Step 2 is to remove the duplicate factors!
Remove x+4 and x+5
x-5 over (x+2)(x-5) times 1 over x-3 = 1 over x+2 times 1 over x-3
Step 3 is to multiply the numerators and the denominators.
End result is 1 over (x+2)(x-3)
Answer:
65 mph on level road
Step-by-step explanation:
Set b as average speed on the level road and (b-20) = average speed on the winding road
Distance = speed * time
Level Road distance + winding road dististance = 285 miles
Substituting b and (b-20), we have,
3b + 2(b-20) = 285
3b + 2b - 40 = 285
5b = 285 + 40
5b = 325
b= 325/5
b = 65 mph on level road

Answer:
(1/7, 1)
Step-by-step explanation:
By "answer," you probably meant "solution." What is the "solution of the system of linear equations
- 5y = - 5
+ 7x +6y=7
The first eqation can be solved for y: y = 1. Substitute 1 for y in the secon equation. Then 7x + 6(1) = 7, or 7x = 1, or x = 1/7.
The solution to this system is (1/7, 1)
