answer :448
1. You con solve the quadratic equation x^2+20x+100=50<span> by following the proccedure below:
2. Pass the number 50 from the right member to the left member. Then you obtain:
x^2+20x+100-50=0
</span><span> x^2+20x+50=0
</span><span>
3. Then, you must apply the quadratic equation, which is:
x=(-b±√(b^2-4ac))/2a
</span><span>x^2+20x+50=0
</span><span>
a=1
b=20
c=50
4. Therefore, when you simplify, the result is:
-10</span><span>±5</span>√2 (It is the last option).<span>
</span>
Answer:
x ≤ - 5
Step-by-step explanation:
Given
- 2x - 1 ≥ 9 ( add 1 to both sides )
- 2x ≥ 10
Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.
x ≤ - 5
