Answer:

x = -0.17   and    x = -5.83

Step-by-step explanation:

We are asked to solve the quadratic equation

x^2+6\,x+1=0

We use the quadratic formula using a = 1, b = 6 and c = 1

for a general quadratic equation of the form: ax^2+bx+c=0

Then, the solutions are given by;

x=\frac{-6+/-\sqrt{36-4\,(1)\,(1)} }{2} =\frac{-6+/-\sqrt{32} }{2}

which produces the two following answers (rounded to two decimals):

x = -0.17   and    x = -5.83

-13.2 + 0.5x &gt; 0.1x + 20
Georgia [21]
First add 13.2 to both sides to get 0.5x > 0.1x + 33.2.
Then subtract 0.1x from both sides to get 0.4x > 33.2.
Lastly, divide each side by 0.4 to get a final answer of x > 83.
Hope this helps!

Which inequality can be used to represent this problem? (HELP ASAP, IM TIMED)
Nadya [2.5K]

Propane costs $3.50 per hundred pounds,

and there is a $6 monthly delivery fee.  

A family has budgeted $85 for their propane this month.

Let  'x' hundreds of pounds can the family use without going over budget

Here family has budgeted $85 for their propane.

So the cost for Propane  = $ 3.5x

One month delivery fee $6

Therefore cost + delivery charge not exceed $85

So 3.5x + 6 ≤ 85

3.5x=85-6 =79

x = 22.57

Therefore 22 hundreds of pounds can the family use without going over budget
