What is the answer to -2/3x4

Answer:

C

Step-by-step explanation:

The function is formed of 2 straight lines

The equation of a straight line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate the slope using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (2, - 2) ← endpoints of left line

m = [tex]\frac{-2+5}{2+4}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Note the line crosses the y- axis at (0, - 3) ⇒ c = - 3

y = [tex]\frac{1}{2}[/tex] x - 3 for x <  2 ( arrow on line points left )

Repeat

with (x₁, y₁ ) = (2, - 2) and (x₂, y₂ ) = (3, 1) ← 2 points on right line

m = [tex]\frac{1+2}{3-2}[/tex] = [tex]\frac{3}{1}[/tex] = 3, thus

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 1), then

1 = 9 + c ⇒ c = 1 - 9 = - 8

y = 3x - 8 for x ≥ 2 ( arrow on line points right )

The sum of the first 1000 consecutive odd counting numbers is 1,000,000.

To find the sum of the first 1000 consecutive odd counting numbers, we need to recognize a pattern and utilize a simple formula.

Step 1: Identify the Sequence of Odd Numbers

The first few odd counting numbers are:

1, 3, 5, 7, 9, 11, 13, ...

Step 2: Determine the Formula for the Sum

The sum of the first n odd counting numbers can be calculated using the formula:

Sum = n²

This means that the sum of the first n consecutive odd numbers is equal to the square of n.

Step 3: Apply the Formula to Our Problem

In this case, we want to find the sum of the first 1000 odd numbers. Therefore, we set n to 1000:

Sum = 1000²

Step 4: Calculate the Value

Now, we perform the calculation:

Sum = 1000 * 1000 = 1,000,000

Answer:

[tex](x,y) -----> (x+9,y-12)[/tex]

Step-by-step explanation:

we know that

[tex]A(7, 3) ----> A'(16,-9)[/tex]

The rule of the translation is equal to

[tex](x,y) -----> (x+a,y+b)[/tex]

Find the values of a and b

[tex](7,3) -----> (7+a,3+b)[/tex]

we have that

[tex]7+a=16[/tex] ----> [tex]a=16-7=9[/tex]

[tex]3+b=-9[/tex] ---->[tex]b=-9-3=-12[/tex]

substitute the values of a and b

[tex](x,y) -----> (x+9,y-12)[/tex]

That means----> The translation is 9 units right and 12 units down

Step-by-step explanation:

1.

KM bisects so NKM and MKL are equal

2 (3x + 5) + 8x + 2 = 180 (straight angle)

6x + 10 + 8x + 2 = 180

6x + 8x = 180 - 10 - 2

14x = 168

x = 168/14

x = 12

3*12+5 = 41

m MKN = 41

The greatest whole possible whole number length of the unknown side is 9 inches

Solution:

Two sides of an acute triangle measure 5 inches and 8 inches

The length of the longest side is unknown

We have to find the length of unknown side

The longest side of any triangle is a hypotenuse

For a acute triangle we know:

If c is the longest side of a acute triangle, a and b are other two sides of a acute triangle then the condition that relates these three sides are given as:

[tex]c^2<a^2+b^2[/tex]

Here in this sum,

a = 5 inches

b = 8 inches

c = ?

Substituting we get,

[tex]c^2< 5^2+8^2\\\\c^2 < 25 + 64\\\\c^2 < 89\\\\c < 9.4[/tex]

On rounding to nearest whole number,

c < 9

Hence, to the greatest whole possible whole number length of the unknown side is 9 inches

Step-by-step explanation:

addition (+) expression the students used to find the answer.

Solution:

Given data: A student is asked to find the sum of 197 and 413.

Sum means adding two numbers or variables.

For addition, we use + symbol to add two numbers.

First add last digit of the numbers (7+3) = 10.

Put 0 in last and carry 1 to the next left digit top.

Add middle digits with carry over 1 (1 + 9 + 1) = 11

Put 1 and carry another 1 to the next left digit top.

Add first digit of the numbers with carry over 1 (1 + 1 + 4) = 6

Sum of 197 + 413 = 197 + 413

                            = 610

Answer:

1. Translation 5 units to the left and 1 unit down

2. Reflection across the x-axis

Step-by-step explanation:

Triangle XYZ has its vertices at points X(-6,2), Y(-4,7) and Z(-2,2).

1. Translate triangle XYZ 5 units to the left and 1 unit down. This translation has the rule:

[tex](x,y)\rightarrow (x-5,y-1)[/tex]

Then

[tex]X(-6,2)\rightarrow X'(-11,1);[/tex]

[tex]Y(-4,7)\rightarrow Y'(-9,6);[/tex]

[tex]Z(-2,2)\rightarrow Z'(-7,1).[/tex]

2. Reflect triangle X'Y'Z' across the x-axis. This reflection has the rule:

[tex](x,y)\rightarrow (x,-y)[/tex]

Then

[tex]X'(-11,1)\rightarrow X''(-11,-1);[/tex]

[tex]Y'(-9,6)\rightarrow Y''(-9,-6);[/tex]

[tex]Z'(-7,1)\rightarrow Z''(-7,-1)[/tex]

These points are exactly the vertices of the triangle X''Y''Z''.

The sequence of transformations is translation, rotation, reflection, and dilation.

The sequence of transformations that maps triangle XYZ onto triangle X"Y"Z" is:

Translation: Move the triangle in a linear direction without rotating it.

Rotation: Rotate the triangle about a fixed point or axis.

Reflection: Mirror the triangle across a line known as the axis of reflection.

Dilation: Increase or decrease the size of the triangle while preserving its shape.

By applying these transformations in the specified sequence, triangle XYZ can be mapped onto triangle X"Y"Z".

The function to calculate the number of illiterate people in Sylvania t years from today is P(t) = 9000 * (3/5)^t.

To write a function that gives the number of illiterate people in Sylvania, P(t), t years from today, we can use the following formula:

P(t) = 9000 * (3/5)^t

This formula represents the reduction in the number of illiterate people by 3/5 each year. To calculate the number of illiterate people t years from today, we multiply the initial number of illiterate people (9000) by the reduction factor (3/5) raised to the power of t.

Answer: 9000( 1 - 3/5 ) ^t

Step-by-step explanation:

The measure of the angle is;

200.64 degrees ⇒ B

200 degrees 38' 24" ⇒ C

Step-by-step explanation:

To convert the measure of an angle from degrees to radians or from radians to degrees use these rules

∵ The measure of an angle is 3.5 radians

- We need to change its measure to degree, use the 2nd rule

∵ π = 3.14

∴ Its measure in degree = [tex](3.5).(\frac{180}{3.14})[/tex]

∴ Its measure in degree = 200.64°

To find its measure in degree, minutes and seconds, multiply the number before decimal point by 60 to find the number of minutes

∵ 1° = 60'

∵ 0.64 × 60 = 38.4

- That means the number of minutes is 38

∵ 1' = 60"

∵ 0.4 × 60 = 24

- That means the number of seconds is 24

∴ The measure of the angle is 200° 38' 24"

The measure of the angle is;

200.64 degrees

200 degrees 38' 24"

Answer:

y=4x-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(0-8)/(1-3)

m=-8/-2

m=4

y-y1=m(x-x1)

y-8=4(x-3)

y=4x-12+8

y=4x-4

Answer:y - 4x + 4 = 0

Step-by-step explanation: Formula for equation of a line passing through two coordinates is

y - y₁                 y₂ - y₁

______  =       ______

x - x₁                  x₂ - x₁

Therefore,            y₂ -y₁                                                                                                  

        y - y₁      =      ____      ×    ( x - x₁ )

                             x₂ - x₁

where x₁ =3, y₁ =8, x₂ = 1 and y₂ 0

Now substitute for the value

y - 8 = 0 - 8

         ______    x     ( x - 3 )

           1 - 3

Therefore y - 8 = -8/-2 × (x - 3 )

y - 8 = -8/-2 × (x - 3)

y -8 = 4 × (x - 3 )

y - 8 = 4( x - 3 )

y - 8 = 4x - 12, when the brackets are open,

So y = 4x - 12 + 8

    y = 4x - 4

Therefore the equation of the line is

y - 4x + 4 = 0

Answer:

The radius of the cylinder is 4 cm.

Step-by-step explanation:

Given:

radius of cone = 6 cm

height of the cone = 8 cm

height of cylinder = 6 cm

We need to find the radius of cylinder.

Solution:

First we will find the volume of cone.

Volume of cone is one third time square of radius times height times π.

framing in equation form we get;

Volume of cone = [tex]\frac{1}{3}\pi r^2h = \frac{1}{3}\pi\times 6^2\times 8 \approx 301.44 \ cm^3[/tex]

Now Volume of cylinder is given by square of radius times height times π.

framing in equation form we get;

Volume of cylinder = [tex]\pi r^2h=18.84r^2[/tex]

Now it has been given that;

Volume of cone is equal to Volume of cylinder.

so we can say that

[tex]18.84r^2=301.44[/tex]

Dividing both side by 18.84 we get;

[tex]\frac{18.84r^2}{18.84}=\frac{301.84}{18.84}\\\\r^2\approx16[/tex]

Taking square root on both side we get;

[tex]\sqrt{r^2}=\sqrt{16} \\\\r=4\ cm[/tex]

Hence the radius of the cylinder is 4 cm.

Answer:

It’s FALSE

Step-by-step explanation:

The correct option will the new price is 120% of the old one because the price increases by 20%, which is added to 100%.

Percent of change is determined by the difference between the two values divided by the orginal one, then multiplied by 100.

i.e. percent of change=(change in value/original value)*100

So according to the asked question,

old value of the shoes=$25

new value of the shoes=$30

change in value=30-25=$5

percent of change=((30-25)/25)*100=20%

hence price increases by 20%.

If the old price is 100 and price increases by 20% then new price will be 120.

So the new price is 120% of the old one.

in another way we can calculate that

old value*x%=new value

⇒old value*x/100=new value

⇒x=new value*100/old value=30*100/25=120%

Therefore the new price is 120% of the old one because the price increases by 20%, which is added to 100%.
