2.5 hours. You take the total amount of kilometers and divide it by the kph (kilometers per hour), which in this case is 11. If you do that, you'll get your answer of 2.5 hours or 2 hours and 30 minutes.

What are the three differences between an inconsistent system and a consistent and independent system. Explan?
RUDIKE [14]
Hey there Mejia021274,
1) Independent systems have exactly one solution:
x + y = 1
x - y = 3
x = 2, y = -1

2) Inconsistent systems have no solutions :
5x + y = 6
5x + y = 10
There is no solution as 5x + y cannot be equal to 6 and 10

3) Consistent systems have a lot of solutions:
x+y = 5 
<span>2x+2y = 10 </span>
<span>A few solutions to this system are (1,4), (2,3), (3,2), (4,1), (5,0), and so on.
</span>
Hope this helps :))

Simplify square root of 1008 ( V` Represents the square root sign.)
Alexus [3.1K]
So first factor it
1008=2*2*2*2*3*3*7
group them in similar pairs
1008=(2*2)(2*2)(3*3)*7
now remember we can do
\sqrt{xy}= \sqrt{x} \sqrt{y} so
\sqrt{1008}= (\sqrt{2*2}) (\sqrt{2*2}) (\sqrt{3*3}) (\sqrt{7})=
2*2*3*\sqrt{7}=
12√7

the answer is B

liberstina [14]

Answer:

f(x) + g(x) = x² - 10x + 9

General Formulas and Concepts:

<u>Algebra I</u>

  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = x² - 11x + 18

g(x) = x - 9

<u>Step 2: Find f(x) + g(x)</u>

  1. Substitute:                              f(x) + g(x) = x² - 11x + 18 + x - 9
  2. Combine like terms (x):          f(x) + g(x) = x² - 10x + 9
