Answer: [tex]x < 4[/tex]

Step-by-step explanation:

Our inequality is [tex]3x-3 < 9[/tex]

We will add 3 to both sides. (addition property of equality)

Simplify [tex]9 + 3 9+3 9+3 ~to ~12[/tex].

Then divide both sides by 3. (division property of equality)

[tex]3x[/tex]÷[tex]3 < 12[/tex]÷[tex]3[/tex]

[tex]\frac{3x}{3} < \frac{12}{3}[/tex]

Simplify [tex]312~to~4[/tex].

The trend line passes through (10, 9) and (35, 0) will be 9x + 25y = 315.

Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by

[tex]\rm (y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)[/tex]

The scatter plot with the trend line below shows the data comparing wind speed and wind chill. Wind Chill (˚F) Wind Speed (mph). The trend line passes through (10, 9) and (35, 0).

Write an equation for the trend line.

(x₁, y₁) → (10, 9)

(x₂, y₂) → (35, 0)

Then we have

        y - 9 = -9/25(x - 10)

25y - 225 = -9x + 90

 9x + 25y = 315

Answer:

x ≈ 10.7

Step-by-step explanation:

Is given in the picture that x is the radius of the circle.

The radius of a circle and the tangent line to the circle form a right angle, therefore our triangle is a right triangle.

We can  apply the Pythagorean Theorem to find one equation that will have one unknown x.

         (x+12)² = x² +20² , use that (a+b)² = a²+b²+2ab

x²+12²+2·x·12 = x² +20², subtract x² from both sides of the equation

     12² + 24x  = 20², subtract 12² from both sides of the equation

              24x = 20²-12², raise to power and combine like terms

              24x = 256, divide by 24  both sides of the equation

                  x = 10.6666666..., round to the nearest tenth

                 x ≈ 10.7

Answer:

[tex]\sf \left(\dfrac{1}{11},\dfrac{3}{11}\right)[/tex]

Step-by-step explanation:

The orthocenter is the point of intersection of the altitudes of a triangle.

(The altitude is the line that passes through the vertex and is perpendicular to the side opposite the vertex).

**Refer to attached diagram**

DC, EA and FB are the perpendicular lines drawn from the three vertices D, E and F.

[tex]\sf Let\:(x_1,y_1)=D\implies(x_1,y_1)=(1,3)[/tex]

[tex]\sf Let\:(x_2,y_2)=E\implies (x_2,y_2)= (-1,0)[/tex]

[tex]\sf Let\:(x_3,y_3)= F\implies (x_3,y_3)=(2,-1)[/tex]

G (x, y) is the intersection point of the three altitudes of the triangle, i.e. the orthocenter.

To find the point of intersection (orthocenter), we need to create linear equations for the altitudes, then equate them to find the point of intersection.

We only need to work with 2 altitudes.

Calculate the slopes of two sides of the triangle.

[tex]\sf \implies Slope\:of\:EF=\dfrac{y_3-y_2}{x_3-x_2}=\dfrac{-1-0}{2-(-1)}=-\dfrac{1}{3}[/tex]

[tex]\sf \implies Slope\:of\:DF=\dfrac{y_3-y_1}{x_3-x_1}=\dfrac{-1-3}{2-1}=-4[/tex]

As the slopes of the altitudes are perpendicular to the slopes of the sides:

[tex]\textsf{Slope of DC}=\sf \dfrac{-1}{\textsf{slope of EF}}=\dfrac{-1}{-\frac{1}{3}}=3[/tex]

[tex]\textsf{Slope of EA}=\dfrac{-1}{\textsf{slope of DF}}=\sf \dfrac{-1}{-4}=\dfrac{1}{4}[/tex]

Using point D (1, 3) and the slope of DC to create a linear equation for DC using the point-slope form of a linear equation:

[tex]\sf \implies y-y_1=m(x-x_1)[/tex]

[tex]\sf \implies y-3=3(x-1)[/tex]

[tex]\implies \sf y=3x[/tex]

Using point E (-1, 0) and the slope of EA to create a linear equation for EA using the point-slope form of a linear equation:

[tex]\sf \implies y-y_1=m(x-x_1)[/tex]

[tex]\sf \implies y-0=\dfrac{1}{4}(x-(-1))[/tex]

[tex]\sf \implies y=\dfrac{1}{4}x+\dfrac{1}{4}[/tex]

To find the x-value of the point of intersection (the orthocenter), equate the equations and solve for x:

[tex]\implies \sf 3x=\dfrac{1}{4}x+\dfrac{1}{4}[/tex]

[tex]\implies \sf \dfrac{11}{4}x=\dfrac{1}{4}[/tex]

[tex]\implies \sf 11x=1[/tex]

[tex]\implies \sf x=\dfrac{1}{11}[/tex]

To find the y-value of the point of intersection (the orthocenter), substitute the found value of x into the equation for line DC:

[tex]\implies \sf y=3\left(\dfrac{1}{11}\right)[/tex]

[tex]\implies \sf y=\dfrac{3}{11}[/tex]

Therefore, the orthocenter is at point:

[tex]\sf \left(\dfrac{1}{11},\dfrac{3}{11}\right)[/tex]

Answer:

[tex] \frac{5}{4} [/tex]

Step-by-step explanation:

To find the average of any amount of numbers, just add all the given numbers together and then divide by the amount of numbers given, in this case it would be :

The chronological organization allows us to organize the events sequentially according to the date of their occurrence.

The image shows several tables that refer to historical events around the world that we must organize chronologically.

To organize the events chronologically we must know the date on which they occurred, for this we must search for complementary information and establish the date of each one of them, especially the year.

Later, we can organize them and we have two alternatives, from the most recent to the oldest or from the oldest to the most recent. In this case we are going to organize them from the most recent to the oldest, so they would look like this:

I picked the points (0, -4) and (-2,-10) to find the gradient of the line

M= rise/run

= 6/2

=3

Y-intercept is at - 4

Y= 3x - 4 is equation of the line given

Reciprocal of 3 is 1/3

(m1 x m2 = - 1)

So, to make - 1, our second gradient should be negative.

Gradient of the perpendicular line will be - 1/3

Y= - 1/3x + c

Substitute value of x & y into the equation

(-6,6) means x = - 6, y = 6

y = - 1/3x +c

6 = - 1/3 x - 6 + c

6 = 2 + c

-2

4 = c

the constant term is the term with only a numeric value

in this case the constant term is 1

the coefficient of the term 2u is 2 ( the value in front of the variable u )

the coefficient of the term 9u is therefore 9

there are 3 terms in the expression 2u , 9v , 1

these terms are being added together , thus

the probability of having a winning raffle ticket is 15%.

The computation shows the radius of the circle that is inscribed in the isosceles triangle will be 3.33cm.

From the information given, the isosceles triangle the length of a base is 10 cm and the length of a leg is 13 cm.

Let A = area of the triangle

Let S = semi perimeter of the triangle.

The radius will be: = A/S

where,

[tex]S = \dfrac{(a + b + c)}{2} = \dfrac{(13 + 13 + 10)}{2} = 18[/tex]

The radius will be:

 [tex]=\dfrac{(\sqrt{18} - \sqrt{13})(\sqrt{18} - \sqrt{13})(\sqrt{18} - \sqrt{10})} { 18}[/tex]

= 3.33cm

Answer:

15 feet

Step-by-step explanation:

From the question above,we are asked to find the volume of a cabinet with the following dimensions:

Height is five feet

Width is eighteen inches

And a depth of two feet.

Here it is quite obvious that we ate dealing with a cuboidal object since its dimensions differ from one another.

So volume of a cuboid as we all know is :

Length multiplied by width and then height

We should head straight away to the calculations, but we need to remember that the width is in inches and needs to be converted to feet

1 inch = 1/12 feet

18 inches = 18× 1/12

= 1.5 feet

L×W×H

= 1.5×5×2

= 15 feet

Answer:

The length of the other two legs are 6√2.

since the hypotenuse is one of the legs multiplied by √2.

dividing the hypotenuse by √2 will get the length of one leg. since it is a 45 45 90 triangle, the length of the two legs are the same.

12/√2= 12√2/2= 6√2

Using the area of a rectangle, it is found that 35 bags are needed to cover the rectangular lawn.

The area of a rectangle of length l and width w is given by the multiplication of the measures, that is:

A = lw

In this problem, we have that the measures in feet are l = 360, w = 190, hence the area in square feet is given by:

A = 360 x 190 = 68,400.

The number of bags is then given by:

68,400/2,000 = 34.2

The equilibrium price is $14 and the quantity is 24.

Equilibrium is the place in the market where there is no trend for change.

Buyers’ and sellers’ plans accord, and consequently quantity demanded equals quantity supplied.

The equilibrium price occurs when the quantity demanded equals the quantity supplied.

The demand and supply functions are, respectively:

Demand and supply in a market are described by the following equations: QD = 66-3p and qs = -4 + 2p.

The equilibrium price and quantity are;

QD = QS

66-3p = -4 + 2p

66 + 4 = 2p + 3p

70 = 5p

p = 70/5

p = 14

QD = 66-3p

QD = 66-3 × 14

QD = 66- 42

QD = 24

Hence, the equilibrium price is $14 and the quantity is 24.
