PLEASE HELP!!!

Which of the following values could x represent in the bar diagram?
ABC or D?

Work Shown:

[tex]y = \frac{1}{9}x+5\\\\9y = x+45\\\\9y-45 = x\\\\-45 = x-9y\\\\x-9y = -45\\\\[/tex]

The last equation is in the form Ax+By = C where A = 1, B = -9, C = -45

In the second step, I multiplied each term by 9 to clear out the fraction.

Answer:

(2-i√7)+(4i)

Step-by-step explanation:

(2-[tex]\sqrt{-4+-3}[/tex])+ ([tex]\sqrt{-16}[/tex] )

(2-i√7)+(4i)

Answer:

4.5

so I did 9 /2 = 4.5

Answer:

4.5 or 9/2 or 4 1/2

Step-by-step explanation:

You divide 9 by 2, to get 4.5 in number form. 9/2 for improper fraction form and 4 1/2 for whole number fraction.

Given that,

A food truck is selling 2 burritos for $5.

Solution,

We need to find the relationship between burritos and dollars.

2 burritos = $5

To find the value of 1 burrito. Divide 5 by 2 as follows :

[tex]1\ \text{burrito}=$\dfrac{5}{2}\\\\1\ \text{burrito}=$2.5[/tex]

Hence, the relation between burritos and dollars is " [tex]1\ \text{burrito}=$2.5[/tex]"

Answer:

Area of the shaded part is 3.14 square unit.

Step-by-step explanation:

Area of the shaded part = Area of large semicircle - (Area of two small semi circles)

Area of large semicircle with center O = [tex]\frac{1}{2}(\pi r^2)[/tex]

                                                                = [tex]\frac{1}{2}\pi (2)^{2}[/tex]

                                                                = 2π

Area of semicircle with center O' = [tex]\frac{1}{2}\pi (1)^2[/tex]

                                                      = [tex]\frac{\pi }{2}[/tex]

Area of semicircle with center O" = [tex]\frac{\pi }{2}[/tex]

Now substitute these values in the formula,

Area of shaded part = [tex]2\pi - (\frac{\pi }{2}+\frac{\pi }{2})[/tex]

                                  = [tex]\pi[/tex]

                                  = 3.14 square unit

Area of the shaded part is 3.14 square unit.

Step-by-step explanation:

The cubic function passes the x-axis only once,

so there is 1 distinct real zeroes and 2 complex zeroes.

The function has only one real zero and two complex zeroes. Then the correct option is D.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The graph of the cubic function is shown.

The intersection of the curve with the x-axis is known as the zeroes of the function.

From the graph, the curve that cut the x-axis is only one point. Then the function has only one real zero and two complex zeroes.

Thus, the correct option is D.

Answer:

Step-by-step explanation:

Let's consider an exponential function as,

f(x) = 2ˣ

Now we prepare the input-output value table to get the ordered pairs to be plotted.

f(x)     0.25     0.5          1             2            4           8

x         -2         -1            0            1             2           3    

By plotting these points we get the graph as attached.

Therefore, second option in the last attachment will be the correct option.

Answer:

(30, 25)

Step-by-step explanation:

Substitute (2/3)x + 5 for y in the second equation:

7x - 3([2/3]x + 5) = 15

Then:

7x - 2x - 15 = 15, or:

5x = 30.  Thus, x = 30, and from the first equation we get:

y = (2/3)(30) + 5 = 20 + 5 = 25

The solution is (30, 25)

Answer:

800 miles

Step-by-step explanation

Step one

A truck can be rented from

Company A for ​$130 a day plus ​$0.20 per mile

Let the number of miles be x

And the total charges be y

y=130+0.2x—-------1

Company B charges ​$50 a day plus ​$0.30 per mile

y=50+0.3x--------2

Equate 1 and 2

130+0.2x=50+0.3x

130-50=0.3x-02x

80=0.1x

x=80/0.1

x=800 Miles

Answer:

106 sq meters

Step-by-step explanation:

Break the figure down. I have attached an image as you can see see below.

The figure consists of three rectangles

So Area of rectangle 1 is = 4 x 7 = 28 sq meters

So Area of rectangle 2 is = 10 x 5 = 50 sq meters

So Area of rectangle 3 is = Area of rectangle 1 = 28 sq meters as they are the same rectangles

So area of the whole figure is =  Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3

Area of whole figure is = 28 + 50 + 28

Area of whole figure is = 106 sq meters.

Answer:

There is no variable factor common to 24a and 6

Step-by-step explanation:

First number = 24a

Other number = 6

Pime factorisation of 24a = 2×2×3×2×a

Pime factorisation of 6= 3×2

Common factors = 6

Hence, there is no variable factor common to 24a and 6, Other common factor is 6.

Answer:

Step-by-step explanation:

The required graph of the given function d(x)=−1/2x−3 has been shown.

Given that, to plot the graph of the linear function,  d(x)=−1/2x−3.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
The graph of the liner function d(x)=−1/2x−3 can be plot by putting the values of the x in the equation which gives the value of y by calculating such an ordered pair we can plot the curve of the liner equation on the graph. i.e.
At x = 0
d(0) = -1/2 * (0) - 3
d(0) = -3
So, the ordered pair will be (0, -3).
Now, put x = 2
d(2) = -1/2 * 2 - 3
d(2) = -1 - 3
d(2) = - 4
So the ordered pair will be (2, -4)
joining these two points will show the graph of the given equation d(x)=−1/2x−3.

Thus, the required graph of the given function d(x)=−1/2x−3 has been shown.

Given:

Usual cost of a bottle of sparkling water = $1.69 each

This week they are on sale for 4 for $5.

To find:

Did you pay more or less for the bottle this week?

Solution:

We have,

Usual cost of 1 bottle = $1.69

On sale, cost of 4 bottles = $5

On sale, cost of 1 bottles = [tex]\dfrac{\$5}{4}[/tex]

                                         = $1.25

Since, $1.25 is less than $1.69, therefore the unit cost on sale is less than usual unit cost.

Hence, you pay less for the bottle this week.

Answer:

[tex] - {4} < x < - 6 \\ [/tex]

Step-by-step explanation:

[tex]5 < - 4x - 11 < 13[/tex]

Add 11 to both sides of the inequality to make - 4x stand alone

[tex]5 + 11 < - 4x - 11 + 11 < 13 + 11 \\ 16 < - 4x < 24[/tex]

Divide both sides by - 4

[tex] - \frac{16}{4} < \frac{ - 4x}{ - 4} < - \frac{24}{4} \\ - {4} < x < - 6[/tex]

Reverse the signs

We have the final answer as
