Write an equivalent expression for (2m+3)(m-1).

Answer:

1. The negative sign on an exponent means the reciprocal. A negative exponent tells how many times to divide a base number.

2. A positive tells how many times to multiply a base number.

25.07 × 5.4 = 135.378

Step-by-step explanation:

In placement of the decimal point in multiplication , first check the numbers that will multiply and count the individual decimal points in the numbers. In this case, 25.07 × 5.4 = 2 * 1 -------decimal place The answer should have  2+1 = 3 decimal places-----note the addition sign 25.07 × 5.4 = 135.378 ---------the answer has 3 decimal places The first answer is incorrect because ; 2.52 × 27.94 = 704.088 ----2 *2 = 4 , but the answer has 3 The second answer is incorrect because; 94.1 × 2.5 = 23.525 -----1 * 1= 2 decimal places, the answer has 3 The third answer is incorrect because ; 1.83 × 2.9 = 53.07--------2*1= 3 decimal places , the answer has 2

Answer: D. 4

Step-by-step explanation:

The correct option is Option D: the value of g(1) is 4.

An inverse function is a function which reverses the function direction for which the range of the function becomes the domain and the domain of the function becomes the range of the inverse function.

If y =  f(x) is the given function then x = f⁻¹(y) is the inverse function.

Here, given in the question the value of x and the value of f(x).

for which f(-1)= -3

f(1)= -1

f(4)= 1

f(6)= 4

f(7)= 6

So let the value of f(x) is y

we can write y=f(x)

applying inverse on both side

⇒f⁻¹(y)= f⁻¹(f(x))

⇒f⁻¹(y)= x

⇒ x= f⁻¹(y)

given that the inverse of f(x) is g(x)

so now the equation will be

⇒ x= f⁻¹(y)=g)y)

⇒ x= g(y)

according to the above function at the value of y, the inverse of the function will be g(y)=  f⁻¹(y)

so from the table it is clear that at the value of x=4, f(x)=y=1.

So at y=1, 1=f(4)

so applying inverse on both side

⇒ f⁻¹(1)= f⁻¹(f(4))

⇒ f⁻¹(1)= 4

⇒g(1)= 4

Therefore the value of the g(1)= 4.

[tex]Domain: \left \{ -\infty<x<\infty \\\right\}[/tex]

[tex]Range:\left\{-\infty<f(x)<\infty\right\}[/tex]

Step-by-step explanation:

[tex]x+y=180[/tex]

First, let's put this equation into slope-intercept form by subtracting [tex]x[/tex] from both sides of the equation:

[tex]y=-x+180[/tex]

Let's graph this (see the attached photo.)

As you see we have a straight line. If you are able to graph a straight line, the domain and range will be all real numbers. This can be represented as:

[tex]Domain: \left \{ -\infty<x<\infty \\\right\}[/tex]

- or -

[tex]Domain:(-\infty,\infty)[/tex]

~

[tex]Range:\left\{-\infty<f(x)<\infty\right\}[/tex]

- or -

[tex]Range:(-\infty,\infty)[/tex]

Answer:

C it's just c trust me sooooooo

The value of x is 12.

Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. Angles that are vertically opposed to one another are equal.

The two angle are (4x - 25)° and (2x - 1)°,

Since, both the angles are vertically opposite angle,

Therefore, by the vertically opposite angle property,

Both the angles will be equal.

4x - 25 = 2x - 1

2x = 24

x = 12

The value of x is 12.

Answer:

The quantity is 12

Step-by-step explanation:

Here, we want to find the solution to the equation.

Let the quantity we are looking for be x;

According to the question;

The quantity plus a quarter of the quantity = 15

x + 1/4(x) = 15

x + x/4 = 15

Multiply through by 4

4x + (x/4)*4 = 15 * 4

4x + x = 60

5x = 60

x = 60/5

x = 12

Answer:

The integer that represents the change in the temperature each week = 5

The temperature of the weather drops 5°F each week

Step-by-step explanation:

The given parameters regarding the weather are;

The range over which the temperature dropped = 20°F

The duration over which the temperature dropped = 4 weeks

The rate at which the weather dropped each week = The same amount (constant rate)

Therefore, we have;

For a constant rate of change, the rate of change of the temperature of the weather, m, is given as follows;

m = (The change in the temperature)/(The duration of the change)

m = 20°F/(4 weeks) = 5°F/week

The integer that represents the change in the temperature each week = 5

x = - [tex]\frac{14}{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{3}{4}[/tex] (x + 5 [tex]\frac{1}{2}[/tex] ) = [tex]\frac{5}{8}[/tex]

Multiply both sides by 8 to clear the fractions

6(x + 5 [tex]\frac{1}{2}[/tex] ) = 5 ← distribute parenthesis on left side

6x + 33 = 5 ( subtract 33 from both sides )

6x = - 28 ( divide both sides by 6 )

x = [tex]\frac{-28}{6}[/tex] = - [tex]\frac{14}{3}[/tex]
