Option D is correct, the region above of the line y=x/2-3 that we can write as  y>x/2-3

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

We know by reading the exercise that the company estimates same day delivery as a region of the miles.

y>x/2-3

We need to represent this region in a graph.

One way is to find the graph of y=x/2-3

This line will divide the plane into two regions. Then, using any point that verifies the original equation  we can find the graph.

y=x/2-3

If x=0

y=-3

The point (0, -3)  is the interception of the line with y-axis.

Now if y=0

0=x/2-3

3=x/2

6=x

The point (6, 0) is the interception of the line with x-axis.

We know that  y>x/2-3 will be the region above of or below of the line y=x/2-3

Now using an arbitrary point (0,0), for example  and replacing in the expression :

0>-3

The point  (0, 0) verifies the expression. Therefore, this point belongs to the region.

Finally, we conclude that the region is the region above of the line y=x/2-3 that we can write as  y>x/2-3 and the correct option is D.

Hence , option D is correct, the region above of the line y=x/2-3 that we can write as  y>x/2-3

Let the figure number be x.

Then the equation will be:

3x

There will be 3x circles in the figure number x.

So, number of circles in 50th figure will be

= 3(50)

= 3 × 50

= 150 circles

The number of circles in the 50th figure is 150 circles.

A sequence in mathematics is a ordered set of objects or numbers which are related with something.

For example, 1, 3, 5, ..... is a sequence of odd numbers.

Here a pattern is shown in the form of the circles.

In the Figure 1, there are 3 circles.

In the figure 2, there are 6 circles.

In the figure 3, there are 9 circles.

It is clear that the pattern is in such a way that 3 circles are increasing to each succeeding figure.

So for the nth figure,

Number of circles will be 3n.

So for 50th figure, number of circles = 3 × 50 = 150 circles

Hence the number of circles in the 50th figure is 150.

Answer:

78.4

Step-by-step explanation:

You add them all up and divide by however many numbers there are.

Answer:

78.4

Step-by-step explanation:

To find the mean of something, you need to add all the values together, then divide the sum by the number of numbers there are.

The sum of all the numbers is 784, and there are 10 numbers.

So, the equation you need to solve is:

784 / 10 = ?

This equals 78.4, so the mean is 78.4.

Answer:

The total earnings for a wage of 6 per hour, an average work week of 8 hours, and working a total of 521 weeks (10 year) per year is:

Not a function

Step-by-step explanation:

when plotted the points do not form a line

Answer:

no its not a function

Explanation:

A function is a relation (a set of ordered pairs) with the additional property that: no two pairs have the same first element and different second elements.

The definition is often stated as: A relation in which every x value is associated with exactly one y value. "Exactly one means one but two or more:

{(1,2);(2,3);(3,4);(2,5)} includes the points (2,3) and (2,5). Therefore these set of pairs are not a function.

Answer:

[tex]r = \±\sqrt{14[/tex]

[tex]Product = -14[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2x} = \frac{r - x}{7}[/tex]

Required

Find all product of real values that satisfy the equation

[tex]\frac{1}{2x} = \frac{r - x}{7}[/tex]

Cross multiply:

[tex]2x(r - x) = 7 * 1[/tex]

[tex]2xr - 2x^2 = 7[/tex]

Subtract 7 from both sides

[tex]2xr - 2x^2 -7= 7 -7[/tex]

[tex]2xr - 2x^2 -7= 0[/tex]

Reorder

[tex]- 2x^2+ 2xr -7= 0[/tex]

Multiply through by -1

[tex]2x^2 - 2xr +7= 0[/tex]

The above represents a quadratic equation and as such could take either of the following conditions.

(1) No real roots:

This possibility does not apply in this case as such, would not be considered.

(2) One real root

This is true if

[tex]b^2 - 4ac = 0[/tex]

For a quadratic equation

[tex]ax^2 + bx + c = 0[/tex]

By comparison with [tex]2x^2 - 2xr +7= 0[/tex]

[tex]a = 2[/tex]

[tex]b = -2r[/tex]

[tex]c =7[/tex]

Substitute these values in [tex]b^2 - 4ac = 0[/tex]

[tex](-2r)^2 - 4 * 2 * 7 = 0[/tex]

[tex]4r^2 - 56 = 0[/tex]

Add 56 to both sides

[tex]4r^2 - 56 + 56= 0 + 56[/tex]

[tex]4r^2 = 56[/tex]

Divide through by 4

[tex]r^2 = 14[/tex]

Take square roots

[tex]\sqrt{r^2} = \±\sqrt{14[/tex]

[tex]r = \±\sqrt{14[/tex]

Hence, the possible values of r are:

[tex]\sqrt{14[/tex] or [tex]-\sqrt{14[/tex]

and the product is:

[tex]Product = \sqrt{14} * -\sqrt{14}[/tex]

[tex]Product = -14[/tex]

Answer:

120 mL of 10% HCL will be used.

Step-by-step explanation:

to solve this, we have to generate an equation for the mixture, to get the volume of 10% HCl needed.

Let the volume needed = x

5% of x + (20% of 60ml) = 10% of ( 60 + x) ml of new mixture

0.05x + (0.2 × 60) = 0.1 × (60 + x)

0.05x + 12 = 6 + 0.1x

12 - 6 = 0.1x - 0.05x

6 = 0.05x

x = 6 ÷ 0.05

x = 120

Therefore, 120 mL of 10% HCL will be used.

The difference between the highest and the lowest temperature will be 143 Fahrenheit.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the highest and lowest recorded temperatures for the state of Texas are 120°F and -23°F.

The difference will be calculated by forming the equation below:-

Difference  = 120 - ( -23 )

Difference  = 120 + 23

Difference  = 143

Therefore, the difference between the highest and the lowest temperature will be 143 Fahrenheit.

Answer:

x-intercept = 6

y-intercept = -4

Slope: m = ⅔

f(3) = -2

Step-by-step explanation:

✔️The x-intercept is the value of x when y = 0. It is the point at which the line of the function intercepts the x-axis. Thus,

x-intercept = 6

✔️The y-intercept is -4. At this point, x = 0. The line intercepts the y-axis at y = -4. Thus,

y-intercept = -4

✔️Slope can be calculated using two points, (0, -4) and (6, 0).

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 -(-4)}{6 - 0} = \frac{4}{6} = \frac{2}{3} [/tex]

Slope: m = ⅔

✔️f(3) means, what is the value of y when x = 3.

From the graph, when x = 3, y = -2.

Therefore,

f(3) = -2
