The factor with the sum of 43 is 18+25

25-18=7 so the difference is 7

hope this helps

Step-by-step explanation:

The difference between the numbers be 25 -18 = 7.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

let the two numbers be x and y

The sum of two numbers is 43

x+ y = 43.....(1)

and, product is 450

xy = 450

y= 450 / x

put value of y in equation (1)

x+ 450/x = 43

x² - 43x + 450 = 0

x² - 18x - 15x + 450 = 0

x( x- 18) - 15 ( x- 18)= 0

(x- 15) ( x- 18)= 0

x= 15, 18

So, the number are 18 and 25.

Hence, the difference between the numbers be 25 -18 = 7.

Answer:

0.33 decades

Step-by-step explanation:

The tiger population loses 3/5 of its size every 0.333 decades.

An exponential function is what can be represented by the equation

y = aˣ

The number of tigers N(t) has been modeled by the equation

[tex]\rm N(t) = 710 * (\dfrac{8}{125})^t[/tex]

The tiger population loses 3/5th of its size in how much decade has to be found.

if it loses 3/5, the remaining will be 3/5 of the size so,

[tex]\rm \dfrac{2}{5} * 710 = 710 * (\dfrac{8}{125})^t\\\\\\dfrac{2}{5} = (\dfrac{8}{125})^t\\[/tex]

Taking log on both the sides

ln 2 - ln 5 = t( ln 8-ln 125)

t= 0.333

Therefore, the tiger population loses 3/5 of its size every 0.333 decades.

Answer:

n = -6

Step-by-step explanation:

n + 2 = -14 - n

2n + 2 = -14

2n = -12

n = -6

Answer:

Step-by-step explanation:

So in the case of "n" being any given variable, (basically saying it could be replaced by x, or any other variable) the answer would be,

n = -6

Work:

n + 2 = -14 - n

Cancel out the negative n on the right side by adding one n to both sides.

n + n = 2n

2n + 2 = -14

Get rid of the 2 on the left side, isolating the variable (2n)

2 + 14 = -12

2n = -12 is the final equation, and the last step is to divide both sides by 2, again isolating the variable.

Final answer is,

n = -6.

Answer:

2x - 2y = - 10

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

- 2(x - y) - 10 = 0 ← distribute parenthesis on left side

- 2x + 2y - 10 = 0 ( add 10 to both sides )

- 2x + 2y = 10 ( multiply through by - 1 )

2x - 2y = - 10 ← in standard form

Answer:1.03125 meter

Step-by-step explanation:

Velocity =330 meter per second

Frequency =320 Hertz

wavelength=velocity ➗ frequency

Wavelength=330 ➗ 320

Wavelength=1.03125 meter

Answer:

1.03 meters

Answer:

a reflection across line m answer is b

Step-by-step explanation:

A reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K". Option B is correct.

The final transformation is to determine that transition states have been shown in the image that describes how pre-image GHJK transformed to image G'H"J"K".

Reflection is defined in an atmosphere as when the beam of light or wave strikes to the plane or curved surface deviates back from the atmosphere.

Steps of Transformation
Pre-image GHJK first rotates anticlockwise by an angle of 90° to G'H'J'K'.
Then G'H'J'K' reflected across the line m to G'H"J"K". It is the final transition state.

Thus, a reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K".
