suppose y varies directly with x, and y = 8 when x = -6. what direct variation equation relates x and y? what is the value of y

Kisachek [45]

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\textit{we also know that }
\begin{cases}
y=8\\
x=-6
\end{cases}\implies 8=k(-6)\implies \cfrac{8}{-6}=k
\\\\\\
-\cfrac{4}{3}=k\qquad therefore\qquad \boxed{y=-\cfrac{4}{3}x}
\\\\\\
\textit{when x = -2, what is \underline{y}?}\qquad y=-\cfrac{4}{3}(-2)$

Avery invested $200 in an account paying an interest rate of 6 7/8%

Maslowich

Answer:

0.73 yrs

Step-by-step explanation:

if t is time in years

quarterly

600 = 200(1 + 0.06625/4)^4t

3 = (1 + 0.06625/4)^4t

ln3 = 4tln(1. + 06625/4)

t = ln3 / (4ln1.0165625)

t = 16.7198 yrs

continuously

600 = 200e^(0.06875t)

3 = e^(0.06875t)

ln3 = 0.06875t

t = ln3 / 0.06875

t = 15.9798 years

Δt = 16.7198 - 15.9798 = 0.73 yrs

Find the area of a trapezoid with a height of 23, base 1 of 10 and base 2 of 18

RSB [31]

Formula of Trapezoid
Area= (b1+b2)/2*h

Area= (10+28)/2 * 23
Area= 38/2 * 23
Area= 19*23
= 437
