Find the smallest solution to the equation 2/3 X² equals 24

iren [92.7K]

Answer:

The smallest solution is -6

Step-by-step explanation:

2/3 x^2 = 24

Multiply each side by 3/2

3/2 *2/3 x^2 = 24*3/2

x^2 = 36

Take the square root of each side

sqrt(x^2) = sqrt(36)

x = ±6

The smallest solution is -6

The largest solution is 6

In the Exercises below, find the scale factor. Then list all pairs of congruent angles and write the ratios of the corresponding

nadezda [96]

Answer:

8) scale factor: 3

angles Q & L, S & N, r & M

sides 10 x 3 = 30, 6 x 3 = 18, 13 x 3 = 39

9) scale factor: 0.4

angles B & F, C & G, D & H, A & E

sides 9 x 0.4 = 3.6, 7.5 x 0.4 = 3, 10 x 0.4 = 4, 12 x 0.4 = 4.8

The graph of a proportional relationship contains the point (8, 4).

Softa [21]

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
(\stackrel{x}{8}~~,~~\stackrel{y}{4})\implies 
\begin{cases}
x=8\\
y=4
\end{cases}\implies 4=k8\implies \cfrac{4}{8}=k\implies \cfrac{1}{2}=k
\\\\\\
\boxed{y=\cfrac{1}{2}x}$
