Answer:
The answer to your question is the second choice
Step-by-step explanation:
4x/ (x - 7) - (x +7) / x
- Find the greatest common factor from x and (x - 7)
GCF = x(x - 7)
- Substract the terms
[4x(x) - (x + 7)(x - 7)] / x(x - 7)
- Simplify
[ 4x² - x² + 49] / x(x - 7)
[ 3x² + 49] / x(x - 7)
- Result
3x² + 49 / x(x - 7)
Answer:
The answer is the second answer choice
Step-by-step explanation:
1. Write as an algebraic equation:
12 + n ≤ 2n - 8
2. Solve for n.
12 + n - 12 ≤ 2n - 8 - 12
n ≤ 2n - 20
n - 2n ≤ 2n - 20 - 2n
-n ≤ -20
Multiply both sides by -1 (this means you must flip the inequality sign).
n ≥ 20
FINAL ANSWER: n ≥ 20
Hope this helps! Feel free to ask for clarification.
Answer:
X = -2
y = 2
Step-by-step explanation:
Substitute y=x + 4 in the second equation to find x
x+4 = 2x + 6
subtract x from both sides
4 = x + 6
subtract 6 from both sides
-2 = x
put -2 in for x in the first equation
y= 2
