Please let me know if its incorrect.

The function g(x) is a horizontal dilation of scale factor k = 5/2 of function f(x).

We know that f(x) is a linear function:

f(x) = 2x + 4

Here we know that:

g(x) = 2*(0.4x) + 4

Notice that function g(x) can be written as:

g(x) = f(0.4*x)

So we have a horizontal dilation, remember a horizontal dilation of scale factor k can be written as:

g(x) =f(x/k)

Notice that 0.4 = 2/5

Then we have a horizontal dilation of scale factor 5/2.

The slope-Intercept form of the given line is y=x-1.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is y-intercept.

The given line passes through (0,-1) and (1,0). Therefore, the slope of the given line can be written as,

Slope of the line, m = [0 - (-1)]/(1 - 0)

                                 = 1 / 1

                                 = 1

Now, the equation of the line passing through (0,-1) can be written as,

y = mx + c

(-1) = 1(0) + C

-1 = 0 + C

C = -1

Substitute all the value in the equation of the line,

y = m(x) + c

y = 1(x) + -1

y = x - 1

Hence, the equation of the given line is y=x-1.

The equation of the line from the given graph can be written as  y = x + 1.

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

From the given graph the points on the straight line can be determined as (1, 0) and (2, 1).

The slope of the line passing through points (x₁, y₁) and (x₂, y₂) is given as slope = (y₂ - y₁) / (x₂ - x₁).

Then, the slope of the line is (2 - 1) / (1 - 0) = 1

Now, the equation of the line can be written as,

(y - 1) / (x - 0) = 1

⇒ y - 1 = x

⇒ y = x + 1

Hence, the equation of the line in slope-intercept form is given as y = x + 1.

The 10th term of an arithmetic sequence is found as the 49.

As per the stated values in question.

Fifth term a5 = 24

8th term a8 = 39.

Let the first term be 'a' and the common difference be 'd'.

Then,

a5 = a + 4d

24 = a + 4d .....eq 1

a8 = a + 7d

39 = a + 7d .....eq 2

Solving eq 1 and 2.

3d = 15

d = 5

a = 4

Now,

a10 = a + 9d

a10 = 4 + (9 x 5)

The dimension of the rectangle of the largest area in an equilateral triangle is √3/4L.

Here we have to find the dimension of the rectangle of the largest area.

Let the distance from the tip of the base of the triangle to the point that the top of the rectangle meets the triangle be x.

The width of the rectangle is √3/2 x.

By this, we can find the area of the rectangle

Area = √3/2x ( L -x) = √3/2 xL - √3/2x²

To find the maximum area we have:

dA/ dx = 0

dA / dx = √3/2L - √3x = 0

From we have to find the value of x,

√3 x = √3/2L

x = L/2

The dimension of rectangle is √3/2x = √3/2(L/2)

                                                             = √3/4 L

Therefore the dimension of the rectangle is √3/4 L.

Balck car can overtake the red car in 2 hrs  

The Relationship between Speed, Distance & Time can be understood by the following formulas

Speed = Distance/Time  

Time = Distance / Speed

Distance = Speed X Time  

Constant speed is also called the uniform rate which involves something traveling at a fixed and steady pace or something moving at some average speed.

Here we have

Two cars are traveling in the same direction along the same route.  

The speed of the Red car = 40 miles per hr

The speed of the Black car = 50 miles per hr  

From above data

The difference between speeds of cars = 50 - 40 = 10 miles per hr

Which means the Black car is chasing the Red car at 10 miles per hr

1000/x - 1000/(x + 1) = 4.5 is an equation in terms of x that simplifies to this quadratic equation 9x² + 9x - 2000 = 0 as shown below.

In Mathematics, the standard form of a quadratic equation is given by this mathematical expression:

ax² + bx + c = 0.

Since Winston changed 1000 rand into euros in both 2014 and 2015, this can be represented by this mathematical expression:

1000/x - 1000/(x + 1) = 4.5

Taking the lowest common multiple (lcm), we have:

1000/x(x + 1) = 4.5

1000/(x² + x) = 4.5

Cross-multiplying, we have the following:

1000 = 4.5(x² + x)

1000 = 4.5x² + 4.5x

Multiplying both sides of the equation by 2, we have:

2 × (1000 = 4.5x² + 4.5x)

2000 = 9x² + 9x

The absolute value graph has its equation to be f(x) = |x - 3| + 5

The graph represents the given parameter

From the graph, we can see that the graph is an absolute value graph

An absolute value graph is represented as

f(x) = a|x - h| + k

Where h and k are the vertex of the graph

In this case, they are

h = 3 and k = 5

This is because the minimum point of the graph is (3, 5)

Substitute values for h and k in the form of the equation

So, we have the following representation

f(x) = a|x - 3| + 5

A point on the graph is (2, 6)

This gives

a|2 - 3| + 5 = 6

When the value of variable a is solved, we have

a = 1

So, the equation becomes

f(x) = 1 * |x - 3| + 5

Evaluate the products

f(x) = |x - 3| + 5

Hence, the equation of the graph is f(x) = |x - 3| + 5
