Find a1, for the arithmetic series with S14 = - 420 and d = -6.

faust18 [17]

$\bf n^{th}\textit{ term of an arithmetic sequence} \\\\ a_n=a_1+(n-1)d\qquad \begin{cases} a_n=n^{th}\ term\\ n=\textit{term position}\\ a_1=\textit{first term}\\ d=\textit{common difference}\\ \cline{1-1} n = 14\\ d= -6 \end{cases} \\\\\\ a_{14}=a_1+(14-1)(-6)\implies a_{14}=a_1+(13)(-6)\implies a_{14}=a_1-78 \\\\[-0.35em] ~\dotfill$

$\bf \textit{sum of a finite arithmetic sequence} \\\\ S_n=\cfrac{n(a_1+a_n)}{2}\qquad \begin{cases} a_n=n^{th}\ term\\ n=\textit{last term's}\\ \qquad position\\ a_1=\textit{first term}\\ \cline{1-1} n= 14\\ S_{14}=-420\\ a_{14}=a_1-78 \end{cases}\implies S_{14}=\cfrac{n(a_1+a_{14})}{2} \\\\\\ -420=\cfrac{14[a_1+(a_1-78)]}{2}\implies -420=7(2a_1-78)\implies \cfrac{-420}{7}=2a_1-78 \\\\\\ -60=2a_1-78\implies 18=2a_1\implies \cfrac{18}{2}=a_1\implies 9=a_1$

The LCD of theses fractions? y/x + y/3+ y+1/y Answers: 3x+y x+3+y 3x+y

Dahasolnce [82]

3xy

y(3y)/3xy + y(xy)/3xy + (y+1)(3x)/3xy 

NOW since all of the fractions have a denominator of 3xy, drop the denominators and solve using the numerators. 

y(3y) + y(xy) + (y+1)(3x) 

3y^2 + xy^2 + 3xy +3x 

cannot simplify further.

Which equation represents the graphed function ?

goldenfox [79]

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1, 1)

m = $\frac{1-3}{1-0}$ = - 2

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

y = - 2x + 3 → A

The length of a rectangle is 8 1/2 inches and the width is 3 1/4 inches. What is the ratio, using whole numbers, of the length t

frosja888 [35]

Short answer 34/13
Start by converting both to improper fractions.

8 1/2 = (2*8 + 1)/2 = 17/2

3 1/4 = (3*4 + 1)/4 = 13/4

Next set up a 4 layer fraction

$\dfrac{\dfrac{17}{2}}{\dfrac{13}{4} }$

Invert the lower fraction and multiply $\dfrac{17}{2}* \dfrac{4}{13}$

Cancel the 2 and the 4 leaving you with a 2 in the numerator. $\dfrac{17*2}{13} =\dfrac{34}{13}$
