(a)  [tex]\frac{x}{x^2 + x + 3}[/tex]

x² + x + 3 will never be zero.

so it will be a continuous function all the time or in the interval (- ∞ ,  ∞).

(b)  [tex]\frac{x + 7}{\sqrt{x} }[/tex]

in this function x cannot be negative or zero.

so the function will be a continuous function for x >0

or in the interval (0,  ∞)

(c)  [tex]x\sqrt{x + 6}[/tex]

for this function, the value of  (x + 6) cannot be a negative value.

or x + 6 >=0 or x >= -6

so the function will be continuous in the interval [-6,  ∞)

Therefore, (a) [tex]\frac{x}{x^2 + x + 3}[/tex] will be a continuous function in interval (- ∞ ,  ∞), (b)   [tex]\frac{x + 7}{\sqrt{x} }[/tex] will be a continuous function in interval (0,  ∞), and (c) [tex]x\sqrt{x + 6}[/tex] will be a continuous function in interval [-6,  ∞).

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

House 1:

The value of the hours is described by an exponential function.

There is an increase of 2% per year.

f(x) = 253,980 x [tex]1.02^x[/tex]

Where x is the number of years.

House 2:

The value of the hours is described by a linear function.

There is an increase of $7000 per year.

f(x) = 256,000 + 7000x

Where x is the number of years.

Now,

For x = 45,

f(45) = 253,980 x [tex]1.02^x[/tex]

f(45) = 253,980 x [tex]1.02^{45}[/tex]

f(45) = $739843.74

f(45) = $739844 ____(1)

f(x) = 256,000 + 7000x

f(45) = 256,000 + 7000 x 45

f(45) = 256,000 + 315000

f(45) = $571000 ______(2)

From (1) and (2),

House 1 will have the greatest value.

The significant difference in the value of either house after 45 years

Answer: x = 3

Step-by-step explanation:

Set the two equal to each other.

-5 (2x+1) = -35

-5 x 2x = -10x , -5 x 1 = -5

-10x -5 = -35

Add 5 to both sides.

-10x = -30

Divide both sides by -10.

x = 3

Answer:

I'm doing this to complete one of the steps. good luck my friend

Step-by-step explanation:

The old box of cereal contained 24.5 ounces.

Take 30% of the original box of cereal.

To find 30% of a number, multiply the number by 0.3.

35 ounces x 0.3 = 10.5 ounces

Subtract 10.5 ounces from 35 ounces.

35 ounces - 10.5 ounces = 24.5 ounces

Answer: The old box of cereal contained 24.5 ounces.

When you take a single number and multiply it by several, you are multiplying. A 5 multiplied by a 4 results in 20 (5 + 5 + 5 + 5). We multiplied the number five by four times. Due to this, multiplication is occasionally referred to as "times."

By definition of similar triangle the sides of ΔABE and ΔACD must be in proportion.

Let us assume that AB = x

x/(x + 12) = 6/15

15x = 6(x + 12)

Yes, it is possible that you have to travel a greater distance to reach point b than to reach point a.

A straight line is a geometric concept that refers to a line that extends indefinitely in two directions without any curvature. It is the shortest distance between two points in Euclidean space and it is represented by an equation in the form of y = mx + b, where m is the slope and b is the y-intercept.

As both destinations, A and B are measured as the crow flies, or in a straight line, and you are able to travel only in straight lines along the main directions (north, south, east, and west), it is possible that the path to point B includes more turns or obstacles, such as buildings or rivers, that require you to travel further in order to reach the destination.

That's why it is possible that you have to travel a greater distance to reach point B than to reach point A.

The values of y are 0, 3 and 7/4 respectively. The solution has been obtained by using the substitution method.

What is substitution method?

The substitution approach is one of the algebraic methods for resolving simultaneous linear equations. It entails swapping any variable to change its value from one equation to another. By doing this, two linear equations are merged into one straightforward equation with one variable.

We are given a rule which is that y= x-1/4

Various values of x are given

So, in order to find the values of y, we will use the substitution method.

When x=1/4, then

⇒y=1/4-1/4

⇒y=0

When x=13/4, then

⇒y=13/4-1/4

⇒y=12/4

⇒y=3

When x=2, then

⇒y=2-1/4

⇒y=8/4-1/4

⇒y=7/4
