A function y = 10 a not linear function

We know that the general form of linear function is f(x) = a + bx

A linear function has one independent variable (for above function x) and one dependent variable(here, f(x)).

The graph of linear function is always a straight line.

Let y = f(x)

So, y = a + bx

where b is the slope of line

and a is the y-intercept

here, the independent variable is x and the dependent variable is y.

We have been given a function y = 10

The graph of y = 10 is a horizontal line parallel to x -axis and intersects y-axis at (0, 10)

There is no y-intercept and the slope is undefined.

Therefore, given function is not a linear function

If the farmer plotted a straight line graph of how many goats he had left over time, the slope of the line would be -14.

To find the slope of the line representing the number of goats the farmer has over time, we need to use the formula:

Where y2 and y1 are the number of goats the farmer has at the end of two different months, and x2 and x1 are the number of months that have passed since he started selling the goats.

In this case:

So the slope of the line is:

The slope of the line is -14, which means that the number of goats the farmer has decreases by 14 goats per month.

It's important to note that when the value of the slope is negative, it means that the line is going down; this means that the farmer is selling goats at a constant rate.

The value of 0.55 hectometers expressed in decimeters is 550 decimeters. The result is obtained by using the concept of unit ladder system.

The common length units are kilometers to milimeter. The conversion can be described in a unit ladder system as follows.

km (kilometers)

  hm (hectometers)

     dam (decameters)

        m (meters)

           dm (decimeters)

              cm (centimeters)

                  mm (millimeters)

Every time the length unit goes down, it is multiplied by ten. Every time the length unit goes up, it is divided by ten.

We have 0.55 hectometers. Express that value in decimeters!

From hectometers to decimeters, it goes down 3 times. So,

0.55 hectometers = 0.55 × 10 × 10 × 10 decimeters

0.55 hectometers = 0.55 × 1000 decimeters

0.55 hectometers = 550 decimeters

a)   Length of the parking lot: 98 m

b)   Width of the pool: 89 m

Step-by-step explanation:

a)   The formula for the area of a rectangle is [tex]A=lw[/tex].

We need to evaluate the length. Lets solve for [tex]l.[/tex]

[tex]A=lw[/tex]

Divide both sides of the equation by [tex]w[/tex].

[tex]\frac{A}{w} =l[/tex]

We are given

[tex]A=8428\\w=86[/tex]

Lets evaluate [tex]l[/tex].

[tex]\frac{8428}{86}=l[/tex]

[tex]l=98[/tex]

b)   The formula for the perimeter of a rectangle is [tex]P=2l+2w[/tex].

We need to evaluate the width. Lets solve for [tex]w[/tex].

[tex]P=2l+2w[/tex]

Subtract [tex]2l[/tex] from both sides of the equation.

[tex]P-2l=2w[/tex]

Divide each term by 2.

[tex]\frac{P}{2} -\frac{2l}{2} =\frac{2w}{2}[/tex]

Simplify.

[tex]w=\frac{P}{2}-l[/tex]

We are given

[tex]P=376\\l=99[/tex]

Lets evaluate [tex]w[/tex].

[tex]w=\frac{376}{2}-99[/tex]

[tex]w=188-99[/tex]

[tex]w=89[/tex]

Answer:

a) 98m , b) 89m

Step-by-step explanation:

(a) Given,

To Find : Length of the Parking lot

Length of a rectangle shape can be derived by the formula,

[tex]l = \frac{A}{w}[/tex]

[tex]l = \frac{8428}{86}[/tex]

[tex]l = 98m[/tex]

Hence , the length of a rectangular parking lot is 98m

(b) Given ,

To Find : The width of the rectangular pool

We take the width as variable 'x'

Now we plug it into the perimeter of a rectangle equation

[tex]376 = 2(99 + x)[/tex]

Using distributive property we,

[tex]376 = 198 + 2x[/tex]

We now flip the equation

[tex]2x + 198 = 376[/tex]

[tex]2x = 376 - 198[/tex] ( Transposing into the right hand side)

[tex]2x = 178[/tex]

[tex]x = \frac{178}{2}[/tex]

[tex]x = 89[/tex][tex]m[/tex]

Hence , the width of the rectangular swimming pool is 89m

The following statements are true for all the numbers. The proof is shown as follows.

We know z₁ = a + bi and zbar= a-bi

z1+z1bar=2a that is purely real. Similarly with z2 +z2bar

z1-z1bar=-2bi that is purely imaginary. Similarly with z2-z2bar

Again

z1bar+z2bar= a-bi+c-di

z1+z2(whole bar)=a+c-(b+d)i

Hence Z₁ + Z₂ = Z₁ + Z₂

Answer: y = 8x

Step-by-step explanation:

The line passes through points (1,8) and (2,16).

Using this, we can first find the slope.

Slope = Δy/Δx = 8/1 = 8

So the slope is 8.

The equation is now

y = 8x + b

Let's use the point (1,8) to find the value of b now.

8 = 8 +b

b = 0

Therefore, y = 8x is the answer.

(you can skip the last step by noticing that the graph passes through the origin)

Answer:

y = 8x

Step-by-step explanation:

From inspection of the given graph, two points on the line are:

Substitute the points into the slope formula to find the slope of the line:

[tex]\implies m=\dfrac{16-0}{2-0}=\dfrac{16}{2}=8[/tex]

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

The y-intercept is the y-value of the point where the line crosses the y-axis. From inspection of the given graph, the y-intercept is zero. So b=0.

Substitute the found slope and y-intercept into the slope-intercept formula to create an equation for the line:

[tex]\implies y=8x+0[/tex]

[tex]\implies y=8x[/tex]

Therefore, the equation for the line in slope-intercept form is:

Mary is mistaken in her conclusion that the two triangles are not similar because size does not determine similarity. Similarity is determined by the proportionality of corresponding sides and the congruence of corresponding angles. Congruence is the equality of all the measures of the corresponding parts of two figures.

In order to determine if two triangles are similar, we must compare the ratios of corresponding sides. If the ratios of corresponding sides are equal, then the triangles are similar. In the diagram, it is not specified what the measures of the sides of the triangles are, so it is not possible to determine if the triangles are similar based on the information given. However, if the ratio of corresponding sides are same, then the triangles are similar.

It is important to note that similarity and congruence are different concepts. Congruence refers to the equality of all measures of corresponding parts of two figures, including side lengths and angles. Similarity refers to the proportionality of corresponding parts, including side lengths and angles. A triangle can be similar to another triangle without being congruent, and congruent triangles are always similar.

In summary, Mary is mistaken because the size of the triangle does not determine similarity, it is determined by the proportionality of corresponding sides and congruence of corresponding angles. Without knowing the measures of the sides of the triangles, it is impossible to determine if the triangles are similar based on the information given.

The quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.

A quadratic equation in standard form is of the form ax² + bx + c, where a, b, and c are constants.

The axis of symmetry of a quadratic equation is given by the line x = -b/2a, so if the axis of symmetry is x=-2, we can set -b/2a = -2, which gives b = 4a.

To find the y-intercept of the quadratic equation, we can set x = 0 and substitute that into the equation: y = a(0)² + b(0) + c = c
So, if the y-intercept is (0,6) then c = 6.

By using above two information, we can write the quadratic equation in standard form as:

a(x+2)² + 4a(x+2) + 6 =0
=> a(x²+4x+4) + 6 = 0
=> a(x²+4x+4) = -6
=> a(x²+4x+4) = -6
=> x² + 4x + 4 = -6/a
=> x² + 4x + 4 = -6/a +10
=> x² + 4x - 6 = 0

So, the quadratic equation in standard form that has an axis of symmetry of x=-2 and y-intercept of (0,6) is x² + 4x - 6 = 0.
