n + 2 = -14 – n please help ik the ansewer i need the woorkkk
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.

Sam opened a money-market account that pays 5% simple interest. He started the account with $7,000 and made no further deposits. When he closed the account, he had earned $700 in interest. How long did he keep his account open?
A.
2 years
B.
5 years
C.
4 years
Answer:
2 years
Step-by-step explanation:
5 x 7000/1000 = 350
350 x 2 = 700
7000 + 700 = 7,700
Therefore, he kept his account open for 2 years gaining 350 dollars in interest per year.

Step-by-step explanation:
The difference between the numbers be 25 -18 = 7.
What is Algebra?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.

Express -2(x - y) -10 = 0 in standard form.
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

N(t) = 710•(8/125)^t
Complete the following sentence about the rate of change in the tiger population. Round your answer to two decimal places
two decimal places.
The tiger population loses 3/5 of its size every ______ decade.
Answer:
0.33 decades
Step-by-step explanation:
The tiger population loses 3/5 of its size every 0.333 decades.
What is an Exponential Function?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.

What is the final transformation in the composition of transformations that maps pre-image GHJK to image G'H"J"K"? a translation to the right a reflection across line m a 90° rotation about point G a 180° rotation about point G
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".

Consider this polynomial: 7kn+2k^2-2k-2n-5+5n^2
What is coefficient for k?
what is the constant term?
What is the degree of the polynomial?
Answer:
coefficient for k: -2
constant term?: -5
degree of the polynomial: 2
Step-by-step explanation:
The coefficient for k is the number that multiplies k. In this case:
7kn+2k^2-2k-2n-5+5n^2
The constant term is the number that doesn't multiply any variable. In this case:
7kn+2k^2-2k-2n-5+5n^2
The degree of a polynomial is the highest of the degrees of the polynomial's monomials. In this case, the highest monomials are:
7kn+2k^2-2k-2n-5+5n^2
all of them second degree

Answer:
1.03 meters
Step-by-step explanation:
Answer:1.03 meters
Step-by-step explanation:
Solving for wavelength
wavelength formula--->wavelength= velocity / frequency
velocity= 330 m/s
