<span>Answer: In an arithmetic sequence, whose first term is a and difference between a term and its preceding term is d,

       the nth term is a+(nâ’1)d and sum of first n terms is n2(2a+(nâ’1)d)

Hence 6th term will be a+5d=8 and 10th term will be a+9d=13

       Subtracting first from second, 4d=5 or d=1.25 and a=8â’5â‹…1.25=8â’6.25=1.75

       Hence sum of first four terms is 42â‹…(2â‹…1.75+3â‹…1.25)=2â‹…(3.5+3.75)=2â‹…7.25=14.50</span>

The temperature in degrees Celsius, c, can be converted to degrees Fahrenheit, f, using the equation f-c+32. Which
Basile [38]

It is a function because every Celsius temperature is associated with only one Fahrenheit temperature. Therefore, option B is true.

<h3>How to convert Celsius into Fahrenheit ?</h3>

We are given that the temperature in degrees Celsius C can be converted to degrees Fahrenheit F

We know that the formula

\dfrac{C}{5} = \dfrac{F - 32}{9}

If we are substituting c = -40

Then, we get

\dfrac{C}{5} = \dfrac{F - 32}{9}\\\\\dfrac{-40}{5} = \dfrac{F - 32}{9}\\\\-8 \times 9 = F - 32\\\\F = -72 + 32\\\\F = -40

For every Celsius temperature, we get only one value of Fahrenheit.

The function is one-one because for every value of Celsius we get a unique value of Fahrenheit.

Hence, it is a function because every Celsius temperature is associated with only one Fahrenheit temperature.

Therefore, option B is true.

split it into 2 rectangles and find the area of each.

10×20= 200 yards squared

22-10= 12

12×12= 144 yards squared

200+144= 344 yards squared

the final answer is 344 yards squared.

X+y=8<br> 2x+y=2 <br> Any one out there please help me out
DiKsa [7]

Answer:

(- 6, 14 )

Step-by-step explanation:

Given the 2 equations

x + y = 8 → (1)

2x + y = 2 → (2)

Multiplying (1) by - 1 and adding to (2) will eliminate the y- term

- x - y = - 8 → (3)

Add (2) and (3) term by term to eliminate y, that is

x = - 6

Substitute x = - 6 into either of the 2 equations and evaluate for y

Substituting into (1)

- 6 + y = 8 ( add 6 to both sides )

y = 14

solution is (- 6, 14 )
