The two functions be[tex]$f(x)=3 x-7$[/tex] and  [tex]$g(x)=\frac{x+1}{x-1}$[/tex] then the value of f(g(-3)) be -1.

An expression, rule, or law in mathematics that specifies the relationship between an independent variable and a dependent variable (the dependent variable). In mathematics and the sciences, functions are fundamental for constructing physical relationships.

A function is an equation with just one solution for every value of y in the equation. A function pairs each input of a particular type with exactly one output. Instead of y, it is typical to name functions f(x) or g(x).

If a function produces the same outcome regardless of how the input is represented without changing its value, it is said to be well defined.

Let the given two functions be

[tex]$$\begin{aligned}& f(x)=3 x-7 \\& g(x)=\frac{x+1}{x-1}\end{aligned}$$[/tex]

f(g(-3)) = f(g(x = 3)) = f(3 - 1) = f(4/2) = f(2)

f(x = 2) = 3 × 2-7 = 6 - 7 = -1

Therefore, the correct answer is option A. -1.

The complete question is:

Consider these functions:

[tex]$$\begin{aligned}& f(x)=3 x-7 \\& g(x)=\frac{x+1}{x-1}\end{aligned}$$[/tex]

A. Peg is walking with a speed of 3 miles per hour.

B. The completed table is given below.

C. If Peg and Raj started at the same time from the same place on the

trail, they are 1.5 miles apart after 3 hours.

D. After 4 hours Peg and Raj will be 2 miles apart.

What is speed?

The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

From the graph it can be seen that -

In 1 hour Peg walks 3 miles.

In 2 hours Peg walks 6 miles.

In 3 hours Peg walks 9 miles.

In 4 hours Peg walks 12 miles.

Therefore, the speed of Peg is 3 miles/hour.

It is given that Raj walks 2.5 miles/hour.

So, to complete the table use the formula speed = distance/time.

distance = speed × time

When time = 0 hours

Raj (0) = 2.5 × 0

Raj (0) = 0 miles

When time = 1 hours

Raj (1) = 2.5 × 1

Raj (1) = 2.5 miles

When time = 2 hours

Raj (2) = 2.5 × 2

Raj (2) = 5 miles

When time = 3 hours

Raj (3) = 2.5 × 3

Raj (3) = 7.5 miles

Now, Raj and Peg started at the same time.

After 3 hours Peg reaches 9 miles and Raj reaches 7.5 miles.

The difference between their distance is -

9 - 7.5

1.5 miles

Now, when time = 4 hours

Raj (4) = 2.5 × 4

Raj (4) = 10 miles

After 4 hours Peg reaches 12 miles and Raj reaches 10 miles.

The difference between their distance is -

12 - 10

2 miles

Therefore, after 3 hours and 4 hours the difference between Pe and Raj is 1.5 miles and 2 miles respectively.

The given equation has 161700 distinct solution.

If a sum of non-negative integers whose values is pre-defined say m is equal to a fixed value say n such that:x1+x2+x3+...+xm=n then the total combination of m non negative integers x1,x2,...xm in mathematical form can be written as: n+m−1Cm−1.

The above problem can also be written as:

x1+x2+x3+x4=100x1≥1x2≥2x3≥0x4≥0

Here x3 and x4 are non-negative integers and there is a restriction on x1 and x2.

Removing the restriction on x1 and x2  as:100 - 1 - 2 = 97

The number of distinct solution that the equation x1+x2+x3+x4=100 has is equivalent to the non-negative solution. of x1+x2+x3+x4=97 and is given by:

97+4−1C4−1=100C3=161700

Hence, the number of distinct solution that the equation x1+x2+x3+x4=100 has is 161700.

The solutions of equations basically depends on the power of variables present on it .

The solutions of equations also show that the how much the power of variables Is present that times it cuts the axis .

For example

1.if x+2=0 then x=—2 that means it has one solution and it also means it cut the x -axis one time .

2.if x^2–4=0 then x have two values that is x=+2,x=—2 it also means it cut the x-axis two times

The value of x for the given corresponding angles is, 7 degree.

What is corresponding angles?

In geometry, corresponding sides and corresponding angles of polygons are compared as part of the tests for congruence and similarity. In these tests, the order of adjacency is maintained by pairing each side and each angle of one polygon with a side or angle of the other polygon.

Given:

m || n

The angles (7x - 4) and (5x + 10) are corresponding angles.

We have to find the value of x.

Since, the angles are corresponding angles and corresponding angles are equal when the lines are parallel.

⇒ 7x - 4 = 5x + 10

Add 4 on both sides,

7x - 4 + 4 = 5x + 10 + 4

7x = 5x + 14

Subtract 5x on both sides,

7x - 5x = 5x + 14 - 5x

2x = 14

Divide both sides by 2

⇒  x = 7

Hence,  the value of x for the given corresponding angles is, 7 degree.

For A, I got 81 cards. I'm pretty sure that's correct.

For B , there can be 1 attribute that is different and the other 3 can be the same, there can be 2 that are different and 2 can be the same, there can be 3 that are different and 1 is the same, or all 4 attributes are different.

If 1 is different and the other 3 are the same, there are [tex]$\binom{4}{1}[/tex]= 4$ sets.

If there are 2 different and 2 are the same, there are[tex]$\binom{4}{2}[/tex]= 6$ sets.

If there are 3 different and 1 is the same, there are [tex]$\binom{4}{2}[/tex] = 4$ sets.

But I don't know how many sets there are if all 4 are different.

To get my final answer for b, I would add all the sets up.

(b) There are 108/3 = 36 unique sets.

(c) For the first card, there are 3 ways to choose the number.  For the second, there 2 choices, and then there is only 1 choice.  So there are 3*2*1 = 6 ways that the numbers can be chosen.  Doing this for the other attributes, we get 6*6*24*6 ways.  But the order of cards doesn't matter in a set, so we divide by 3!: 6*6*24*6/3! = 864.  So there are 864 sets for part (c).

(d) The cards can have the same number, color, shape, or shading.  If all the colors are the same, then there are 6*24*6/3! = 144 sets.  If all the numbers are the same, then there are 144 sets.  We get the same number for shape and shading, so there are 4*144 = 576 sets for part (d).

(e) We need to choose two of the attributes.  There are C(4,2) = 6 ways of choosing two attributes.  For each of these two attributes, there are 3 options.  For the other two attributes, there are 3 ways of assigning the choices, so there are 6*3*3*3*3 = 486 sets for part (e)

(f) First we choose which attributes are the same.  There are C(4,3) = 4 ways of choosing which attributes are the same.  There are then 3*3*4 = 36 ways to assign which is which for each of these three attributes, and there are 4 ways to assign the choices for the fourth attribute, so there are 4*36*4 = 576 sets for part (f).

This means that the only solution to the equation is x = 0, which implies that the vectors in the matrix are not linear combinations of each other.

b. No, if s is a linearly dependent set, then each vector is not necessarily a linear combination of the other vectors in s. A linear combination is a combination of two or more vectors where each vector is multiplied by a scalar and then added together.

A linearly dependent set means that one of the vectors can be expressed as a linear combination of the other vectors, but not necessarily all of them.c. No, the columns of any 4 5 matrix are not necessarily linearly dependent.

Linear dependence is determined by the rank of the matrix. If the rank of the matrix is equal to the number of columns, then the columns of the matrix are linearly independent.

However, if the rank of the matrix is less than the number of columns, then the columns of the matrix are linearly dependent.

Dividend ÷ Divisor = Quotient and Remainder

When a dividend is divided by a divisor, we get the value of the quotient in the result.

The quotient is the result of dividing one integer by another. For example, in 8÷ 4 = 2, the result of the division is 2, hence the quotient is 2. The dividend is 8 and the divisor is 4.

According to the Quotient Rule, the derivative of a quotient equals the denominator times the numerator's derivative minus the numerator times the denominator's derivative, all divided by the denominator's square.

This is the rule we employ when dividing one exponential equation by another. According to the quotient rule, we must subtract the exponent in the denominator from the exponent in the numerator, but the bases must be the same.
