Answer:
-5
negative nine-halves
Step-by-step explanation:
we know that
In the quadratic equation
If
then
The system has no real numbers solutions
we have
so
substitute
<u><em>Verify each case</em></u>
case 1) -5
For c=-5
substitute
------> is true
therefore
The value of c=-5 will cause the quadratic equation to have no real number solutions
case 2) negative nine-halves
For c=-9/2
substitute
------> is true
therefore
The value of c=-9/2 will cause the quadratic equation to have no real number solutions
case 3) negative one-quarter
For c=-1/4
substitute
------> is not true
therefore
The value of c=-1/4 will not cause the quadratic equation to have no real number solutions
case 4) 1
For c=1
substitute
------> is not true
therefore
The value of c=1 will not cause the quadratic equation to have no real number solutions
case 5) 9 Over 4
For c=9/4
substitute
------> is not true
therefore
The value of c=9/4 will not cause the quadratic equation to have no real number solutions
Answer:
55 minutes
Step-by-step explanation
He started waiting at <u>12:35 P.M.</u> If we're assuming this is the same day, you're able to add the minutes until you get to <u>1:00 P.M.</u>, which is around 25 minutes. Afterwards, you need to <u>add</u> another 30 minutes to get to the train's time of arrival, which means you should get 55 minutes!
