The equation in the form of y=mx+b will be y= -3/4x+2

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that the inequality is y< -3/4x+2,

We have to write the inequality in the form of y=mx+b

A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Thus, the equation in the form of y=mx+b will be y= -3/4x+2

Answer:

Step-by-step explanation:

2 + 3/8 = 7/8

2 x 7/8 = 7/4

2 + 5/8 = 9/8

2 x 9/8 = 9/4

2 + 6/8 = 8/8

2 x 8/8 = 16/8

2 + 7/8 = 15/8

2 x 15/8 = 15/4

The equations have no solution.

6x – 2 – 3x = 3x – 2

10 + 6x = 15 + 9x – 3x

11 + 3x – 7 = 6x + 5 – 3x.

We have determine from the given option which option has no solution.

When an equation has a solution?

An equation with no solution will be an equation when simplified, which will be a false statement.

The equation, 6x – 2 – 3x = 3x – 2

add like terms,

3x-2=3x-2

So we get,This equation has no solution

10 + 6x = 15 + 9x – 3x

10+6x=15+6x

add like terms we cannot find the value of x.

Therefore the given equation has no solution.

11 + 3x – 7 = 6x + 5 – 3x.

add like terms,

4+3x=3x-5

we cannot find the value of x.

So this equation has no solution.

Therefore, The equations 6x – 2 – 3x = 3x – 2,10 + 6x = 15 + 9x – 3x and 11 + 3x – 7 = 6x + 5 – 3x have no solution.

7 is a value of k that transforms f into g, where g(x) = f(x) + k. Using the concept of x and y-axis:

A two-dimensional number line, like two perpendicular axes, can be used as a coordinate system. This coordinate system is typical: The x-axis and y-axis are the names of the horizontal and vertical axes, respectively. The origin is the point at which all lines in a coordinate system intersect.

The coordinates that are shown on the x and y axes give rise to their respective names. The vertical y-axis is aligned with the horizontal x-axis. They are referred to as axes because they are perpendicular to one another.

From the graph it is observe that,

Graph of Function f(x) cut at y axis in the point 3

graph of function g(x)  cut y axis in the point 4

So, the difference between the cut of y axis is k

Thus, {g(x)-f(x)=k}

The  equations that can be used to solve for the length of the room are

(b) y²-5y=750  ,    (c) 750-y(y-5)=0  and   (e) (y+25)(y-30)=0

Given that:

The area of rectangular room is 750 square feet.

Let the length of the rectangular room be y feet.

Since the width of the rectangular 5 less than the length of the room.

Then the width of the given rectangular room is (y-5) feet.

We know the area of a rectangular plot is = Length×width.

Thus , the area of the rectangular room is = y(y-5) square feet

According to problem,

area of the rectangular room =  750 square feet

⇒ y(y-5) =750.........(1)

⇒ y²-5y=750 .......(2)

⇒ y²-5y-750=0

⇒ y²-30y+25y-750=0

⇒ y(y-30)+25(y-30)=0

⇒ (y-30)(y+25)=0 ......(3)

⇒ y-30=0 or, y+25=0

⇒ y= 30, -25

∵ the length of a rectangle can't be negative.

So, y=30.

We can rewrite the equation (1) in form of

(i)

y(y-5) =750

⇒750= y(y-5)

⇒750-y(y-5)=0.......(4)

(ii)

y(y-5) =750

⇒y(y-5) -750=0.......(5)

Hence , the  equations that can be used to solve for the length of the room are

(b) y²-5y=750  ,    (c) 750-y(y-5)=0  and   (e) (y+25)(y-30)=0

Step-by-step explanation:

Answer:

6,3

Step-by-step explanation:

The quadratic equation that models the company's costs is y = 25(x - 16)² + 1000

From the question, we have the following parameters that can be used in our computation:

Minimum cost of $1000 at 16 hours

Operating cost of $2600 at 8 hours

A quadratic equation is represented as

y = a(x - h)² + k

The minimum point is the vertex

So, we have

(h, k) = (16, 1000)

Substitute (h, k) = (16, 1000) in y = a(x - h)² + k

y = a(x - 16)² + 1000

The cost of $2600 at 8 hours means

(x, y)  = (8, 2600)

So, we have

2600 = a(8 - 16)² + 1000

Evaluate the difference

1600 = a(8 - 16)²

So, we have

64a = 1600

Divide by 64

a = 25

Substitute a = 25 in y = a(x - 16)² + 1000

y = 25(x - 16)² + 1000

Hence, the equation is y = 25(x - 16)² + 1000
