Answer:
d. The equation has one solution and there is not enough information to determine the direction of the parabola.
Step-by-step explanation:
For a general quadratic equation
y = ax² +bx +c
the solution is
The discriminant (D) is the part of the quadratic formula underneath the radical: b² - 4ac.
D tells us whether there are
- two different real solutions
- two identical real solutions ("one solution")
- two complex solutions.
If D= 0,
and there are two identical solutions ("one solution").
The direction of the parabola depends on the sign of a.
That information is not given, so we cannot determine the direction of the parabola.
Answer:
<u>375 </u>hamburgers were sold on Sunday.
Step-by-step explanation:
<u>This question is incomplete, so the complete question is below:</u>
A local hamburger shop sold a combined total of 695 hamburgers and cheeseburgers on Sunday. There were 55 fewer cheeseburgers sold than hamburgers.<u> How many hamburgers were sold on Sunday?</u>
Now, to find the number of hamburgers were sold on Sunday.
Let the number of hamburgers be
As, given there were 55 fewer cheeseburgers sold than hamburgers.
So, the number of cheeseburgers is
Total combined hamburgers and cheeseburgers sold on Sunday = 695.
So, to get the number of hamburgers sold on Sunday we set an equation:
<u><em>According to question:</em></u>
<em>Adding both sides by 55 we get:</em>
<em>Dividing both sides by 2 we get:</em>
The number of hamburgers sold = 375.
Therefore, 375 hamburgers were sold on Sunday.
