Answer:

Step-by-step explanation:
The quadratic formula is:

The discriminant of a quadratic is just the expression under the square root, or
. This can tell us the number of solutions a quadratic has.
If the discriminant is:
- Positive = 2 real solutions
- Equal to Zero = 1 real double/repeated solution
- Negative = 0 real solutions, but 2 imaginary solutions
Our quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.

Answer:
The “blank” is 4
Step-by-step explanation:
4 1/4= 16/x+ 1/4
We want to get rid of the 1/4. So we subtract it from both sides and get
4= 16/x
We know that if we put 16 divided by 4, you get 4.
This gives you 4= 16/4.
This is your final answer.
Answer:
18 number of glasses of lemonade can she pour
Step-by-step explanation:
Unit rate defined as rates are expressed as a quantity of 1, such as 3 feet per second or 8 miles per hour, they are called unit rates.
As per the statement: Rita has 3/4 gallon of lemonade she pours 1/24 gallon of lemonade into each glass.
Number of lemonade Rita has = 3/4 gallon

By definition of unit rate;
