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.

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:

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

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:

24

Step-by-step explanation:

first you multiply 200 by 12, Then you divide that by 100. your final product is 24, hope that helps

Answer:

C. 6%

Step-by-step explanation:

First we need to divide the amount of people who got the allergic reaction by how many people were there.

So: 12 ÷ 200 = 0.06

Now, we need to multiply 0.06 by a whole percent, the whole percent is 100.

So: 0.06 × 100 = 6

6% of the people had a mild allergic reaction.

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.

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:

(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)

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:

Here is the summary:

Step-by-step explanation:

Given the equation

The points which satisfy the equation y=13x+5

y = 13x+5

Checking the point (0, 5)

5 = 13(0)+5

5 = 0 + 5

5 = 5

TRUE

Checking the point (-2, -21)

-21 = 13(-2)+5

-21 = -26 + 5

-21 = -21

TRUE

The points which satisfy the equation y=-3x

y = -3x

Checking the point (0, 0)

0 = -3(0)

0 = 0

TRUE

Checking the point (-5, -15)

y = -3x

-15 = -3(-5)

-15 = -15

TRUE

Checking the point (-3, 9)

y = -3x

9 = -3(-3)

9 = 9

TRUE

The points which satisfy the equation y=x-10

y = x-10

Checking (8, -2)

-2 = 8 - 10

-2 = -2

TRUE

Therefore, from the above calculations we conclude the summary:
