Answer:

f(x) = -5x + 250

Step-by-step explanation:

* Lets  explain how to solve the problem

- In week 10 the manufacturer fixed 200 cars

- In week 15, the manufacturer fixed 175 cars

- the reduction in the number of cars each week is linear

- The form of the linear equation is y = mx + c, where m is the slope of

 the line which represent the equation and c is the y-intercept

- The slope of the line m = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

  where (x1 , y1) and (x2 , y2) are two points on the line

* Lets solve the problem

- Assume that the weeks' number is x and the cars' number is y

∴ (10 , 200) and (15 , 175) are two points on the line which represent

  the linear equation between the cars' numbers and the weeks

  numbers

∵ Point (x1 , y1) is (10 , 200) and point (x2 , y2) is (15 , 175)

∴ x1 = 10 , x2 = 15 and y1 = 200 and y2 = 175

- Use the rule of the slope above to find m

∴ [tex]m=\frac{175-200}{15-10}=\frac{-25}{5}=-5[/tex]

- Substitute the value of x in the form of the linear equation above

∴ y = -5x + c

- To find c substitute x and y by one the coordinates of one of the

  two points

∵ x = 10 when y = 200

∴ 200 = -5(10) + c

∴ 200 = -50 + c

- Add 50 to both sides

∴ 250 = c

- Substitute the value of c by 250

∴ y = -5x + 250, where the number of cars seen each week is y and

  x is the number of the week

∵ f(x) = y

∴ f(x) = -5x + 250

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]

Part 1) y varies inversely with x. If y = 3 and k (the constant of variation) = 33, what is x?

we have

[tex]y*x=k[/tex]

[tex]y=3[/tex]

[tex]k=33[/tex]

substitute and solve for x

[tex]3*x=33[/tex]

Divide by 3 both sides

[tex]x=33/3[/tex]

[tex]x=11[/tex]

Part 2) y varies inversely with x. When y = 11, x = 5.2. What is the value of k, the constant of inverse variation?

we have

[tex]y*x=k[/tex]

[tex]y=11[/tex]

[tex]x=5.2[/tex]

substitute and solve for k

[tex]11*5.2=k[/tex]

[tex]k=57.2[/tex]  

Part 3) y varies inversely with x, and k (the constant of variation) = 72. What is the value of y when x = 7.8?

we have

[tex]y*x=k[/tex]

[tex]x=7.8[/tex]

[tex]k=72[/tex]

substitute and solve for y

[tex]y*7.8=72[/tex]

Divide by 7.8 both sides

[tex]y=72/7.8[/tex]

[tex]y=9.2[/tex]

Part 4) y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?

we have

[tex]y*x=k[/tex]

[tex]y=8[/tex]

[tex]k=19[/tex]

substitute and solve for x

[tex]8*x=19[/tex]

Divide by 8 both sides

[tex]x=19/8[/tex]

[tex]x=2.375[/tex]

Part 5) y varies inversely with x, and k (the constant of variation) = 23. What is the value of y when x = 7?

we have

[tex]y*x=k[/tex]

[tex]x=7[/tex]

[tex]k=23[/tex]

substitute and solve for y

[tex]y*7=23[/tex]

Divide by 7 both sides

[tex]y=23/7[/tex]

[tex]y=3.3[/tex]

Part 6) y varies inversely with x. When y = 6.7, x = 1. What is the value of k, the constant of inverse variation?

we have

[tex]y*x=k[/tex]

[tex]y=6.7[/tex]

[tex]x=1[/tex]

[tex]6.7*1=k[/tex]

[tex]k=6.7[/tex]

Part 7) y varies inversely with x. When y = 9.6, x = 12. What is the value of k, the constant of inverse variation?

we have

[tex]y*x=k[/tex]

[tex]y=9.6[/tex]

[tex]x=12[/tex]

substitute and solve for k

[tex]9.6*12=k[/tex]

[tex]k=115.2[/tex]

Part 8) y varies inversely with x, and k (the constant of variation) = 5.6. What is the value of y when x = 4?

we have

[tex]y*x=k[/tex]

[tex]x=4[/tex]

[tex]k=5.6[/tex]

substitute and solve for y

[tex]y*4=5.6[/tex]

Divide by 4 both sides

Answer:

Part 1) The smallest x-intercept is x=-1

Part 2) The largest x-intercept is x=6

Part 3) The y-intercept is y=-6

Part 4) The vertex is the point (2.5,-12.25)

Part 5) The equation of the line of symmetry is x=2.5

Step-by-step explanation:

we have

[tex]f(x)=x^{2}-5x-6[/tex]

step 1

Find the x-intercepts

we know that

The x-intercept is the value of x when the value of the function is equal to zero

so

equate the function to zero

[tex]x^{2}-5x-6=0[/tex]

The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]x^{2}-5x-6=0[/tex]

so

[tex]a=1\\b=-5\\c=-6[/tex]

substitute in the formula

[tex]x=\frac{-(-5)(+/-)\sqrt{-5^{2}-4(1)(-6)}} {2(1)}[/tex]

[tex]x=\frac{5(+/-)\sqrt{49}} {2}[/tex]

[tex]x=\frac{5(+/-)7} {2}[/tex]

[tex]x=\frac{5(+)7} {2}=6[/tex]

[tex]x=\frac{5(-)7} {2}=-1[/tex]

therefore

The x-intercepts are

x=-1 and x=6

The smallest x-intercept is x=-1

The largest x-intercept is x=6

step 2

Find the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

so

For x=0

[tex]f(0)=(0)^{2}-5(0)-6[/tex]

[tex]f(0)=-6[/tex]

therefore

The y-intercept is y=-6

step 3

Find the vertex

we know that

The equation of a vertical parabola into vertex form is equal to

[tex]f(x)=a(x-h)^{2}+k[/tex]

where

(h,k) is the vertex

Convert the function into vertex form

[tex]f(x)=x^{2}-5x-6[/tex]

Group terms that contain the same variable, and move the constant to the opposite side of the equation

[tex]f(x)+6=(x^{2}-5x)[/tex]

Complete the square, Remember to balance the equation by adding the same constants to each side

[tex]f(x)+6+2.5^{2}=(x^{2}-5x+2.5^{2})[/tex]

[tex]f(x)+12.25=(x^{2}-5x+6.25)[/tex]

Rewrite as perfect squares

[tex]f(x)+12.25=(x-2.5)^{2}[/tex]

[tex]f(x)=(x-2.5)^{2}-12.25[/tex]

The vertex is the point (2.5,-12.25)

step 4

Find the equation of the line of symmetry

we know that

In a vertical parabola the equation of the line of symmetry is equal to the x-coordinate of the vertex

we have

vertex (2.5,-12.25)

The x-coordinate of the vertex is 2.5

therefore

The equation of the line of symmetry is x=2.5

Given :

Equations  ---  y = x - 5   --- (1)

                       [tex]\rm y = -\dfrac{3}{4}x+2[/tex]    --- (2)

The system of linear equations can be determined by substituting the value of y in terms of x in another equation in order to determine the value of 'x' and by finding the value of 'x', the value of 'y' can also be determined.

Substitute the value of 'y' in equation (2) that is:

[tex]\rm x-5 = -\dfrac{3}{4}x+2[/tex]

Further, simplify the above equation.

[tex]4x - 20 = -3x +8[/tex]

7x = 28

x = 4

Now, substitute the value of 'x' in equation (1) that is:

y = 4 - 5

y = -1

The equation h=2A/b represents combined variation where h varies directly with area (A) and inversely with width (b). The formula indicates how changing one variable affects another in the context of proportional relationships. The mention of molecular cohesion and size pertains to a different scientific context and is not directly related to this mathematical formula.

The formula h=2A/b describes a scenario of combined variation, where h varies directly as the area A and inversely as the width b. Direct variation means that as one variable increases, the other variable increases as well, while inverse variation indicates that as one variable increases, the other decreases. In this case, if the area doubles, h will also double if b remains constant, and if b is halved, h will double, assuming A stays constant.

The provided information about the parameter a describing inter-molecular cohesion and the parameter b describing the effect of molecular size seems to be associated with a completely different context, likely a scientific or chemical formula, rather than the combined variation formula presented in the question. This formula might be relevant to the Born-Oppenheimer surfaces as depicted in Figure 3.1c, which describes a chemical interaction.

Find the midpoint using the midpoint formula

midpoint = [ 0.5(1 - 5), 0.5(- 1 + 3) ] = (- 2, 1 )

Calculate the length using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = - 2, 1 ) and (x₂, y₂ ) = (0, 4 )

d = [tex]\sqrt{(0+2)^2+(4-1)^2}[/tex]

  = [tex]\sqrt{2^2+3^2}[/tex]

  = [tex]\sqrt{4+9}[/tex] = [tex]\sqrt{13}[/tex] ≈ 3.6 ( to 1 dec. place )

Both of these are linear equations with different y-intercepts and different slopes.

Let's analyze the lines:

y = 2x:

This is a linear equation with a slope of 2 and a y-intercept at the origin (0,0). This means that for every unit increase in x, y increases by 2. The graph is a straight line that passes through the origin.

y = 2 - x:

This is also a linear equation, but with a slope of -1 and a y-intercept at (0,2). This means that for every unit increase in x, y decreases by 1. The graph is a straight line that intersects the y-axis at the point (0,2).

Now, let's consider their relationship:

Both equations are linear, so their graphs are straight lines.

Therefore, the graphs of these two equations are lines with different slopes. The line represented by y = 2x slopes upwards, while the line represented by y = 2 - x slopes downwards.

Answer:

  x = {-8/3, 7/2}

Step-by-step explanation:

To use the zero product property, you need the equation in the form of a product that is equal to zero. We can get that by subtracting 56 and factoring the resulting equation.

  6x^2 -5x -56 = 0

  (3x +8)(2x -7) = 0

The zero product property tells us this product is zero only when the factors are zero:

  3x +8 = 0   ⇒   x = -8/3

  2x -7 = 0   ⇒   x = 7/2

The solution is x = {-8/3, 7/2}.

Comment on factoring

Consider the product ...

  (ax +b)(cx +d) = (ac)x^2 +(ad +bc)x +(bd)

Now consider the product of first and last term coefficients compared to the coefficient of the middle term:

  acbd = (ad)(bc)  vs.  ad+bc

We see that the coefficient of the middle term is the sum of two of the factors of the first·last product. This means we want factors of 6·(-56) that have a sum of -5.

  6(-56) = -(2^4)(3)(7) . . . . has 20 divisors.

We're looking for factors that are nearly equal. The clue is given by simplifying the above factoring:

  = -(16)(21) = (16)(-21) . . . . the sum of these factors is -5, as we need.

Again considering the first-last product and the middle coefficient, we see that we can choose ...

  ad = -21, bc = 16; ac = 6, so a=3, c=2, and ...

  (a, b, c, d) = (3, 8, 2, -7)

These values give us the factors we used above.

Note this process gets easier with practice and familiarity with multiplication tables.
