Isolate one variable in the system of equations. Use substitution to create a one-variable equation. Then, set the quadratic equation equal to zero and find the discriminant. If the discriminant is negative, then there are no real number solutions. If the discriminant is zero, then there is one real number solution. If the discriminant is positive, then there are two real number solutions.

Answer:

e2020

Step-by-step explanation:

Use substitution to create a one-variable equation.

Set the quadratic equation equal to zero and find the discriminant.

The value of the discriminant will tell you how many real number solutions the system of equations has

A taxi ride costs p40.00 for the first 500 meters and each additional 300 meters or a fraction there of adds p3.50 to the fare.u
Zarrin [17]

The function which represents the taxi fare in terms of distance d in meter is f(d) = 3.50 ×\frac{d-500}{300} + 40 .

According to the question,

For first 500 meters cost is  40.00 and For each additional 300 meters cost is 3.50 .

Let, the total distance of taxi ride = d meters

Now, representing the equation of taxi fare in terms of distance when distance is less than 500

taxi fare = 3.50 ×  \frac{d-500}{300}  + 40

∴  f(d) = 3.50 ×  \frac{d-500}{300} + 40

Which equations model this problem? A recipe that makes 1 serving calls for 0.1 L of honey. How many servings can Alicia make if
loris [4]
The answer is B. 0.8/0.1 = s

The solution is as follows:
s = honey at hand / honey needed for 1 serving
   = 0.8 L / 0.1 L
   = 8, she can make 8 servings of the recipe

A: 25.12 (26 if your rounding)

B: You have to multiply R by 2 then by pi (3.14)

C: 10.5 (11 if your rounding)

Step-by-step explanation:

For a: A circle's circumference is its diameter multiplied by pi (3.14) To get the diameter you would multiple the radius by 2. Therefore your answer being 25.12 (Round to 26 if you want)

For c: Divide 65 by pi then that answer by two.
