Answer:

Inequality (1) → y > 2x

inequality (2) → x ≥ -2

Step-by-step explanation:

If the inequality (1) is a dotted line passing through origin.

Since, shaded area is above the dotted line,

Equation of the inequality will be in the form of y > mx +b

Here m = slope of the dotted line

b = y-intercept

Since, this line is passing through the origin,

Therefore, y-intercept = 0

Slope 'm' of the line = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

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

                             m = 2

Inequality (1) → y > 2x

Second inequality is represented by the shaded area on the right side of  the dark vertical line, x = -2,

Therefore, inequality 2 will be → x ≥ -2

Answer: x≽-2 and y>2x

Answer:

5x + 3

Step-by-step explanation:

Since we can see DC is the median of Triangle ABC

So it breaks the into two equal parts

Given

AD = 2x + 5

BD = 3x - 2

Now

AB = AB + BD

= 2x + 5 + 3x - 2

= 5x + 3

The question is incomplete, the complete question is;

The radius of the sphere is 10 units.What is the approximate volume of the sphere? Use π = 3.14 and round to the nearest whole cubic unit. cubic units

Answer:

4187 cubic units

Step-by-step explanation:

According to the question;

radius (r) = 10 units

 π = 3.14

Volume of a sphere = 4/3*π*r^3

Substituting values;

V = 4/3*(3.14)*(10)^3

V = 4186.67 cubic units

V = 4187 cubic units (To the nearest whole cubic unit)

Step-by-step explanation:

Transformation involves changing the position of a shape

The transformations and the order in which they were applied are:

A. 90° counter-clockwise rotation, then reflected across the y-axis

From the figure, the coordinate of RST is:

[tex]R= (2,4)[/tex]

[tex]S = (2,8)[/tex]

[tex]T =(-6,8)[/tex]

Using R to illustrate the transformation.

We have

[tex]R= (2,4)[/tex]

First, R is rotated 90 degrees counterclockwise

The rule of this transformation is:

[tex](x,y) \to (-y,x)[/tex]

So, we have:

[tex](2,4) \to (-4,2)[/tex]

Next, the point is reflected across the y-axis.

The rule of this transformation is:

[tex](x,y) \to (-x,y)[/tex]

So, we have:

[tex](-4,2) \to (4,2)[/tex]

From the question, we have the coordinate of R" to be;

[tex]R: =(4,2)[/tex] --- same as the result of the above sequence

Hence, option (A) is correct

Answer:

Por tanto, la cantidad de ingredientes necesarios para 6 personas es:

450 g de queso, 15 ml de leche, 150 g de azúcar, 150 g de mantequilla y 75 g de harina.

Step-by-step explanation:

Por lo tanto:

Para queso

4 personas = 300g de queso

6 personas = x

Cruz multiplicar

4x = 6 × 300g

x = 6 × 300 g / 4

x = 450 g de queso

Por 10ml de leche

4 personas = 10 ml de leche

6 personas = x

Cruz multiplicar

4x = 6 × 10 ml

x = 6 × 10 ml / 4

x = 15 ml

Por 100 g de azúcar

4 personas = 100 g de azúcar

6 personas = x

4x = 6 × 100g

x = 6 × 100 g / 4

x = 150 g de azúcar.

Por 100 g de mantequilla

4 personas = 100 g de mantequilla

6 personas = x

4x = 6 × 100g

x = 6 × 100 g / 4

x = 150 g de mantequilla

Por 50 g de harina

4 personas = 50 g de queso

6 personas = x

4x = 6 × 50g

x = 6 × 50 g / 4

x = 75 g de queso.

Por tanto, la cantidad de ingredientes necesarios para 6 personas es:

450 g de queso, 15 ml de leche, 150 g de azúcar, 150 g de mantequilla y 75 g de harina.

Answer:

The point-slope equation of the line is y - 2 = 3(x + 9)

Step-by-step explanation:

The form of the point-slope equation is y - y1 = m(x - x1), where

∵ The slope of a line is 3

∴ m = 3

∵ The line passes through point (-9, 2)

∵ x1 = -9

∴ y1 = 2

→ Substitute the values of m, x1, and y1 in the point-slope form

∵ y - y1 = m(x - x1)

∴ y - 2 = 3(x - (-9))

→ Remember (-)(-) = (+)

∴ y - 2 = 3(x + 9)

∴ The point-slope equation of the line is y - 2 = 3(x + 9)

Answer:

87

Step-by-step explanation:

Hi!

First you add all of the numbers up together:

77+81+93+97= 348

Next, you divide the answer you got above by how many numbers are in your data set:

348/4 = 87

4 because 77,81,93,97 thats four numbers :)

Therefore, Marla's test average is 87!

So anytime you need find the average of any data set, you just add all the numbers together, then divide by the quantity of numbers there are.

Step-by-step explanation:

Experimental probability : (Number of times event occur / total number of trials)

Total Number of trials = (3 + 4 + 6 + 3) = 16

Experimental probability :

For 1: P(1) :

3/16

For 2 : P(2) :

4/16 = 1/4

For 3: P(3)

6 /16 = 3/8

For 4 : P(4)

3 / 16

Theoretical probability :

The Theoretical probability of 1, 2, 3 and 4 are the same ;

Theoretical probability =

(Required outcome / Total possible outcomes)

For each of 1 - 4

Theoretical probability = 1 /4

Experimental probability of P(2) = 1/ 4 and is Hence, the same as the Theoretical probability

Answer:

x = 12

A = 30

Step-by-step explanation:

Here, we want to solve for the value of x

The angle at the top of the triangle is 8x + 4

The reason for this is because vertically opposite angles are equal

Mathematically;

8x + 4 + 3x - 6 = 130

The reason for this is that opposite interior angles equal the exterior angle

Thus;

8x + 3x + 4- 6 = 130

11x -2 = 130

11x = 130 + 2

11x = 132

x = 132/11

x = 12

The value of A is 3x - 6

A = 3(12)-6

A = 36-6

A = 30

Answer:

Mr. Selan would pay $2.15 for the sandwiches with tax.

Step-by-step explanation:

Given that:

Cost of each sandwich = 99 cents

Cost of two sandwiches = 99*2 = 198 cents

Sales tax = 8.5%

Sales tax = [tex]\frac{8.5}{100}*198=16.8\ cents[/tex]

Sales tax = 17 cents

Total cost = 198 + 17 = 215 cents

Total cost = $2.15

Hence,

Mr. Selan would pay $2.15 for the sandwiches with tax.
