Value of the function [ f(x+ h) - f(x) ] /h in simplest form when f(x) = -2x -1 is equal to -2.

As given,

Given function:

f(x) = -2x -1

Express value of  in simplest form:

f( x + h ) = -2 (x + h ) - 1

             = -2x -2h -1                   ___(1)

Simplify the function by substituting value of f(x +h and f(x),

[f(x + h) - f(x) ] /h

= [ (-2x -2h -1 )- ( -2x -1 ) ] /h

= ( -2x -2h -1 +2x +1 ) /h

= -2h /h

= -2

Therefore, value of the function [ f(x+ h) - f(x) ] /h in simplest form when f(x) = -2x -1 is equal to -2.

From the tape diagram, your allowance and your friends' allowance is $48 and $32 respectively.

What is tape diagram?

A tape diagram is a visual representation that looks like a piece of tape and is used to help with ratio calculations, addition, subtraction, and most frequently multiplication. A divided bar model, fraction strip, length model, or strip diagram are other names for it. It is employed in mathematics education to help elementary school-aged children solve word problems. Students can use a tape diagram as a pictorial model to represent a mathematical relationship or to better understand a mathematical concept. Although they are frequently used with word problems, tape diagrams are helpful for solving many different kinds of math problems.

Let the ratio is given by 3:2 and total is 5
hence, 5 parts represent $80, so each part represents= 80/5= 16
hence, your allowance is 3×16 =48 and your friend allowance is 2×16= 32

The temperature when the pressure is 450 is 225°.

Given:

The pressure of a gas varies directly with the temperature.

So, P ∝ T

P = kT , here k is the constant of proportionality

Pressure(P) = 800psi

Temperature(T) = 400°

Putting the values to get the value of k,

P = kT

800 = 400k

k = 2

We need to find the temperature when the pressure is 450.

​P = kT

450 = 2T

T = 450/2

T = 225°

Therefore, the required temperature is 225°.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

let the integer be x

then, next consecutive odd integer will be x + 2

Now, according to the question :

We have 1 of the number 93

We have 1 of the number 92

We have 1 of the number 94

If the domain of f is ( -1, 1), then the function g defined by g(x) = f((x + 1)/(x - 1)) has a domain of; (-2, 0)

The domain of a function refers to the set of all possible intput values that make the function possible.

Now, we are given the function;

g(x) = f((x + 1)/(x - 1))

The domain would be a set of real numbers excluding 1 because at x = 1, the function is undefined.

Since the domain of  f(x)  is  -1 < x < 1  ,

Then the domain of  f(x + 1)  is  -1 < x + 1 < 1 .

domain of -1 < x + 1 < 1  will simplify to -2 < x < 0

Thus, we can say that the domain of  f(x + 1)  is  (-2, 0).

Thus;

g(x) = f(x + 1) and as such, the domain of  g(x)  is  (-2, 0) .

TheThe number of miles that a signal sent from Station 1 to the satellite and then to Station 2 will have to travel is; 48,135 miles.

Distance from Station 1 to satellite:

tan8.7 = length of longest leg / length of longest leg

tan8.7 =  3963/length of shortest leg

Length of longest leg=3963/tan8.7°

Length of longest leg=3963/0.15302150298

Length of longest leg =25,898 miles

Distance from Station 2 to satellite:

sin 8.7 = length of longest leg / length of hypotenuse

sin  8.7 =  3963/length of hypotenuse

Length of hypotenuse =3963/ sin 8.7

Length of hypotenuse =3963/0.1526082024

Length of hypotenuse=26, 200 miles

Hence,

26, 200 miles  - 3,963 =22,237 miles

Total distance:

Total distance = 25,898 miles  + 22,237 miles

Total distance = 48,135 miles

Step-by-step explanation:

To find the value of the smaller integer, start by letting a variable be that integer. This helps us to refer to the integer with greater ease in our working.

Let the smaller integer be x.

Consecutive numbers refers to numbers coming after one another, such as 1, 2 and 3.

The next integer coming after the integer x would thus be (x +1). Three times the next consecutive integer would then be 3(x +1).

Subtract refers to a minus sign, thus the equation would be:

3(x +1) -x= 23

Expand:

3x +3 -x= 23

Simplify:

2x= 23 -3

2x= 20

Divide both sides by 2:

x= 20 ÷2

x= 10

Thus, the smaller integer is 10.

Carol can make a maximum of 4 smoothies with the available yoghurt

Cups of yoghurt Carol has for making smoothies = 1 5/8 cups

Yoghurt Carol has in improper fractions = 13/8 cups

Cup of yoghurt used to make smoothie = 1/3 cups

Fractions: A numerical value that designates a portion of a whole is used to represent fractions. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.

Number of smoothies Carol can make = Total available yoghurt with Carol/Yoghurt used to make a smoothie

= (13/8)/(1/3)

= 39/8

Converting the fraction into a mixed fraction we get: 4 7/8 smoothies

Based on the dilation, the scale factor of dilation of the point is 1/3

Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.

From the question, we have the following parameters

Dilation rule: Do,k

Point = (9, 6)

Image = (3, 2)

As a general rule of dilation, the following are the properties of a scaled copy of another figure

Using the above as a guide, the scaled factor is calculated as

Scaled factor = Image/Poins
