The expression written by Regina is y + 9, which means adding nine to some number y. None of the given expressions are equivalent to this expression.

The expression written by Regina is y + 9, which means adding nine to some number y. None of the given expressions are equivalent to this expression. In order for two expressions to be equivalent, they must have the same value when the same values are plugged into them. For example, if y is equal to 5, then y + 9 would be equal to

14, while (9. 3 • 4) + y

would be equal to

27, (9+ y (3 = 4))

would be equal to 17, and

(y + 9)(3 = 4)

would be equal to 21. As these values are not equal, the given expressions are not equivalent to the one written by Regina.

Answer:

90

Step-by-step explanation:

each dot = 45 bc 540 / how many dots there are which is 12 = 45 then there are 2 dots worth of 45 making it 90

math

540/12=45

45 x 2 = 90

Answer: 135 students

Step-by-step explanation:

1. Divide 540 (total number of students) by the number of dots (12)

2. So then 540/12= 45

3. Then see how many dots are more then 5 miles away so that is 3 dots (2dots on 6 miles, and 1 dot on 7 miles)

4. After 45*3= 135

Answer:

86.4

Step-by-step explanation:

6x +12 + 4x + 44 = 180

10x +56 = 180

10x = 180 - 56

x = 12.4

180 - 4*12.4 + 44 =86.4

The transformation is shifted up 2 units.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

The given function is f(x)=-2x+3.

Here, the slope m of a line is -2 and y-intercept is 3

A) If the function g(x)=f(x)+k, where k=2.

Now, g(x)=-2x+3+2

g(x)=-2x+5

Here, the slope m of a line is -2 and y-intercept is 5

B) The slope of both functions are same

To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Shifted up 2 units

Therefore, the transformation is shifted up 2 units.

The decimal form of the -1 1/12 is obtained by finding the sum of -1 and -1/12 (-1/12 = -0.08[tex]\overline{3}[/tex] a recurring decimal), which is the option A

A. -1.08[tex]\overline{3}[/tex]

A recurring decimal is a decimal that has a digit or a group of digits that is continuously repeated in the decimal.

The specified expression, -1 1/12, can be presented as follows;

[tex]-1\dfrac{1}{12}[/tex]

The value of the specified expression in decimal form is therefore;

[tex]-1\dfrac{1}{12}= -1+\left( - \dfrac{1}{12}\right)[/tex]

[tex]- \dfrac{1}{12} = -0.08\overline{3}[/tex]

The fraction -1/12, therefore consist of a recurring decimal, with the 3 in the thousandth place after the 8 being the part that repeats.

Therefore, the value of the expression, [tex]-1+\left( - \dfrac{1}{12}\right)[/tex] is -1 + (-0.08[tex]\overline{3}[/tex])

-1 + (-0.08[tex]\overline{3}[/tex]) = -1.08[tex]\overline{3}[/tex]

The specified expression is therefore;

[tex]-1\dfrac{1}{12}[/tex] = -1 + (-0.08[tex]\overline{3}[/tex]) = -1.08[tex]\overline{3}[/tex]

The cleaning company would charge $150 for cleaning two rooms according to the fixed charges.

A fixed amount is a fixed amount or amount established by agreement or contract. This amount is usually a specified amount, does not change over time, and is usually paid on demand or by a certain date. Fixed amounts are commonly used in loans, insurance, and other financial contracts.

This cost is calculated by dividing the difference between the total cost of 6 and 8 rooms by the number of rooms cleaned (6 - 2 or 4).

= ($250 - $320)/4

= $40

This will give you a price of for each additional room.

To calculate the cost of two rooms, simply add the fixed amount of the home visit and double the cost ($40) for each additional room. That's a total of $150 for two rooms.

The range of solutions for the given inequality is -5<y<5.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The given inequality is -6<1/3(6y + 12)<14.

Here, -6<(2y + 4)<14

-6<(2y + 4)

Subtract 4 on both the sides of an inequality, we get

-10<2y

Divide 2 on both the sides of an inequality, we get

-5<y

(2y + 4)<14

Subtract 4 on both the sides of an inequality, we get

2y<10

Divide 2 on both the sides of an inequality, we get

y<5

So, -5<y<5

Therefore, the range of solutions for the given inequality is -5<y<5.

Answer:

x=6.3m

Step-by-step explanation:

Let the opposite side be y in 2nd triangle.

tan 27° = y/9

=> tan 27° X 9 = y

∴ y = 4.585m ≈ 4.59m

cos 43° = y/x

=> cos 43° = 4.59/x

=> cos 43° X x= 4.59

=> x = 4.59/cos 43°

∴ x =  6.276m ≈ 6.3m (corrected to 1 dp)

The area of the semicircle is, 6.28 unit².

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

BC is the diameter of the semicircle.

And, The area of rectangle ABCD is 20 and the length of line AB is 5.

Now, We have;

The area of rectangle ABCD is 20 and the length of line AB is 5.

Let the width of rectangle = x

So, We can formulate;

⇒ 20 = x × 5

⇒ x = 4

Here, the width of rectangle is the diameter of the semicircle.

So, The radius of semicircle = 4 / 2

                                            = 2 units

We know that;

Area of semicircle = π r

Where, 'r' is radius of semicircle.

Hence, We get;

⇒ Area of semicircle = π r

⇒ Area of semicircle = 3.14 × 2

Step-by-step explanation:

From the question we are told that:

 [tex]SinA=\frac{28}{53}[/tex]

 [tex]CosB=\frac{3}{5}[/tex]

Let X be the adjective side to A

Let Y be the opposite side to B

Generally the equation for X is mathematically given by

 [tex]X^2=\sqrt{53^2-28^2}[/tex]

 [tex]X=45[/tex]

Therefore [tex]TanA[/tex]

[tex]TanA=\frac{28}{45}[/tex]

Generally the equation for Y is mathematically given by

 [tex]Y^2=\sqrt{5^2-3^2}[/tex]

 [tex]Y=4[/tex]

Therefore [tex]TanB[/tex]

[tex]TanB=\frac{4}{3}[/tex]

Generally the equation for [tex]Tan(A+B)[/tex] is mathematically given by

[tex]Tan(A+B)=\frac{TanA+TanB}{1-TanA*TanB}[/tex]

[tex]Tan(A+B)=\frac{\frac{28}{45}+(\frac{4}{3})}{1-(\frac{28}{45})*(\frac{4}{3})}[/tex]

If triple of a number added to its half part its equal to the difference between four times the number and 12 then the number is 24.

Two or more expressions with an Equal sign is called as Equation.

Let us consider the number be x

tripple of a number added to its half part

3x+x/2

Difference between four times the number and 12

4x-12

So tripple of a number added to its half part its equal to the difference between four times the number and 12

3x+x/2=4x-12

6x+x=2(4x-12)

Apply distributive property on RHS

7x=8x-24

Subtract 7x on both sides and add 24
