Answer:
discriminant
Step-by-step explanation:
Discriminant is the expression under the radical in a quadratic equation formula that indicates the nature of the solutions real or complex, rational or irrational , single or double root in other words
A discriminant can be said to be used to indicate the nature of the result that a quadratic equation when solved will yield and this can be : rational or irrational , complex or real, single or double roots. and it also indicates by how many it would be
Answer:
40
Step-by-step explanation:
So split it into two shapes. Two rectangles.
Rectangle 1 = 4 * 5 = 20
Rectangle 2 = 2 * 10 = 20
20 + 20 = 40
Each pizza cost $ 12.65
<h3>What is an Equation ?</h3>
An Equation is used in determination of unknown variables in an expression .
It is given that
Brian ordered 3 large cheese pizzas and a salad.
The salad cost $4.95
Total amount spend = $47.60
Tip = $5
The amount spend in food is $ 47.60-5
= $42.60
Let the price of Pizza is x then the equation that can be formed to determine the price of pizza is
3x + salad = 42.60
3x + 4.95 = 42.60
3x = 37.65
x = $12.65
Therefore each pizza cost $ 12.65

<h2><u>
Functions</u></h2>
The relationship between both prices is determined by function (R - 1 = B + 2).
It is clear that for each pound less of brown rice there will be 2 more pounds of beans, with which there is a direct relationship between both quantities, which is determined through a function (R - 1 = B + 2).
Given that brown rice cost $ 2 per pound, and beans cost $ 1 per pound, and Alexa has $ 10 to spend on these items to make a meal for a dinner she is attending, to determine if it is the amount of rice purchased a function of the amount of beans purchased, the following calculation must be performed:
- 2 x 5 + 0 = 10
- 2 x 4 + 2 = 10
- 2 x 3 + 4 = 10
- 2 x 2 + 6 = 10
- 2 x 1 + 8 = 10
- 2 x 0 + 10 = 10
Therefore, it is clear that for each pound less of brown rice there will be 2 more pounds of beans, with which there is a direct relationship between both quantities, which is determined through a function (R - 1 = B + 2).
