Answers

Answer:

12 wooden rulers

23 plastic rulers

Step-by-step explanation:

Total rulers sold - 35

Total profit - $82

1 wooden ruler - $3

1 plastic ruler - $2

$3 x 12 = $36

$2 x 23 = $46

$46 + $36 = $82

12 + 23 = 35 rulers

The store has sold 12 wooden rulers and 23 plastic rulers today.

What are linear and non-linear functions?

A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.

Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.

An example of a non-linear function is a quadratic function.

Let, The number of plastic rulers be denoted by 'P' and the number of wooden rulers is denoted by 'W'.

Given, They have sold 35 total rulers today.

Therefore,

P + W = 35...(i)

Also given, $82 worth of rulers were sold today.

Therefore,

2P + 3W = 82...(ii)

Multiplying the eqn(i) by 2 and subtracting from eqn(ii) we get,

W = 12 and P + 12 = 35 hence P = 23.

So, they sold 12 wooden rulers and 23 plastic rulers.

1. If the discriminant of a quadratic equation is zero, what do you know about the type and number of roots of the quadratic equation?

A. The quadratic equation has one real number root.

B. The quadratic equation has one imaginary and one real number root.

C. The quadratic equation has two imaginary number roots.

D. The quadratic equation has two distinct real number roots.

Answers

Answer:

C

Step-by-step explanation:

Using the concept of the discriminant of a quadratic equation, the correct option is:

A. The quadratic equation has one real number root.

--------------------------

A quadratic equation is given by:

[tex]y = ax^2 + bx + c[/tex]

The discriminant is:

[tex]\Delta = b^2 - 4ac[/tex]

If the discriminant is positive, that is, [tex]\mathbf{\Delta > 0}[/tex], the equation has two distinct real roots.If the discriminant is zero, that is, [tex]\mathbf{\Delta = 0}[/tex], the equation has two equal real roots, which is also considered one real root.If the discriminant is negative, that is, [tex]\mathbf{\Delta < 0}[/tex], the square root of a negative number will be calculated, and thus, the equation has two imaginary number roots.In this question, [tex]\Delta = 0[/tex], thus, one real root, option A.

Answers

Answer:

C

Step-by-step explanation:

The answer is C it was on my test

Slopes are simply the average rate of change of a linear function and graph.

The true statement about the slope of the line is (b) it is -1/2 throughout

From the graph, we have a straight line that passes through the hypotenuse of both triangles.

This means that, the slope of the line is uniform/constant through the points it passes through.

The line passes through the following points

[tex](x,y) = (0,0)\ (-4,2)[/tex]

The slope (m) of the line is calculated using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]m = \frac{2 - 0}{-4- 0}[/tex]

Simplify the expression

[tex]m = \frac{2}{-4}[/tex]

Simplify fraction

[tex]m = -\frac{1}{2}[/tex]

This means that, the slope of the line is -1/2 throughout
