Answer:

x = 6

Step-by-step explanation:

The 'ZERO" of the function is the 'x' value(s) where it crosses the x-axis (and

'y' = ZERO)

Answer:

x = 6

Step-by-step explanation:

the zero of the function is the value of x on the x- axis where the graph crosses.

the graph crosses the x- axis at 6

then the zero is x = 6

Taking into account the definition of a system of linear equations, the weight of meteorite A and meteorite B is 126 tons and 18 tons respectively.

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is, they must give the solution proposed in both equations.

In this case, a system of linear equations must be proposed taking into account that:

You know:

The system of equations to be solved is

[tex]\left \{ {{A=7B} \atop {A+B=144}} \right.[/tex]

It is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, substituting the first equation in the second one you get:

7B + B= 144

Solving:

8B= 144

B= 144÷8

B= 18 tons

Remembering that A= 7B, the value of A is calculated as:

A= 7×18

A= 126 tons

Finally, the weight of meteorite A and meteorite B is 126 tons and 18 tons respectively.

Answer:

your equation is Y = 6

Step-by-step explanation:

Use Midpoint Formula to find the slope M first

Name the coordinates of both points x1 = -2, y1 = -6, x2 = 4,  y2 = 6

Plug them in the formula

M = y2 - y1/ x2 - x1

M =( 6 - 6)/( 4 - (-2))

M = 0/6

M = 0

Then use point slope formula

Plugin the slope M = 0 in the formula and pick one of the points above. Name the coordinates of  the point X1 = 4 and y1 = 6

y - y1 = m(x - x1)

y - 6 = 0(x - 4)

y - 6 = 0

y = 6

your equation is Y = 0x  + 6 but keep in this form y = b

The Inverse of given function F(x) = 1 / 4x is F⁻¹(x) = 1 / 4 x

F(x) = 1 / 4x is a function of x.

Changing F(x) to the variable y

This means that F(x) = 1/4x becomes y = 1/4x.

Changing the variables x and y in the previously obtained equation

This means that we can deduce x = 1 / 4y from the equation y = 1 / 4x.

Solving the newly discovered equation for y

This means that we must simplify the equation by rearranging the terms in order to obtain the equation in terms of the variable x.

x =  1 / 4y

=> 4 y = 1 / x

=> y = 1 / 4 x

As a result, we obtain the required equation.

Switching the variable y with F⁻¹(x)

This assumes, y = 1 / 4 x becomes F⁻¹(x) = 1 / 4 x

Hence, the value of the given function F⁻¹(x) = 1 / 4 x

The line parallel to line  y = 7x - 6 and passing through points  (5, 8)  is

Given data

y = 7x - 6

(5, 8) and is parallel

From the line,  y = 7x - 6, the slope is 7. Since slope of parallel lines are equal, the new line will have same slope and pass through points  (5, 8).

y - 8 = 7 ( x - 5 )

y - 8 = 7x - 35

y = 7x - 35 + 8

y = 7x - 27

The equation of the line parallel to y = 7x - 6 passing through (5, 8) is y = 7x - 27

The equation of the line is parallel to the equation y = 7x - 6.

Parallel line have the same slope.

Therefore, let's represent the equation as follows:

y = mx + b

where

Therefore, the slope of the graph y = 7x - 6 is 7.

The equation of the line that contains (5, 8) and parallel to the graph can be computed as follows

y = 7x + b

let's find the y-intercept

8 = 7(5) + b

8 - 35 = b

b = - 27

We get the equation in logarithmic form as log₁₀ 1000 = 3.

A “logarithmic equation” is an equation which involves the “logarithm” of any expression which is containing a variable.

Now, we have been given an equation:

10 ³ = 1000

We need to write it in the logarithm form.

We know that, it will be written as:

log₁₀ 1000 = 3

Since the power goes after the equal sign, so 3 is placed after the equal sign.

The actual value is taken after log, so 1000 is placed there and the base number is taken as the base for the log, so 10 is taken as the base for the log.

Therefore, we get the equation in logarithmic form as log₁₀ 1000 = 3.

The median of a data set is 9.5

Mean is the ratio of sum of the observations to the total number of observations.

Median is such a number for the arranged data set(ascending or descending order) such that to its left and to its right belong same number of observations.

The median of a data set is the middle number when all of the data points are ordered from smallest to largest. For the data set, the first thing you want to do is put them in order from smallest to largest gives you:

6 6 7 7 7 9 10 10 10 10 11 12

Then we will find the middle of the data set. Since there is an even number of twelve data points; it will be between the sixth and seventh point:

Answer: 176cm

Step-by-step explanation:  To find the circumference of the circle, we will use the circumference formula: 2πr = 2 × 22/7 × 28

We have been given that -

scale = 1:75000.

we have to find out

(a) scale expressed as 1 cm represents n km.

Map scale refers to the ratio between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground

so 1,00,000 cm = 1 km.

(b) given -

distance between two towns on the map is 25 cm.

Find the actual distance, in kilometres, between the two towns.

Scale is given as 1:75000

for 25 cm distance = 25×75000 cm

                              = 18,75,000 cm

therefore 1875000 cm = 18.75 km.

the real distance between two points is 18.75 km.

(c) . The area of the lake in the real world is 3.5 square kilometers.

1 square kilometer is equal to 1 kilometers squared.

since 1 kilometer is equal to 100,000 centimeters, then 1 square kilometer is equal to 100,000^2 centimeters which is equal to 1 * 10^10 square centimeters.

3.5 square kilometers on the map is therefore equal to 3.5 * 10^10 square centimeters.

1 centimeter on the map is equal to 75000 centimeters in the real world.

1 square centimeter on the map is equal to 75000^2 centimeters in the real world which is equal to5625 * 10^6 square centimeters in the real world.

take 3.5 * 10^10 square centimeters in the real world and divide it by 5625 * 10^6 square centimeters and you get .0006 * 10^4 square centimeters which is equal to 6 square centimeters on the map.
