For each direct variation find the constant of variation then find the value of Y when X equals -0.5. Y equals 2 when X equals 3
Readme [11.4K]

For direct variation y varies directly with x, then we use equation y = kx

Where k is the constant of proportionality

Given: Y equals 2 when X equals 3

We plug in 3 for x  and 2 for y and solve for k

y = kx

2 = k(3)

Divide both sides by 3

\frac{2}{3} =k

Now we plug in 2/3 for k  

y=\frac{2}{3}x

Given x=-0.5  and find out y

y=\frac{2}{3}(-0.5)

y=-0.33

the value of y is -0.33 when x=-0.5

Need help ASAP can figure out
s344n2d4d5 [400]

Answer:

Answer is D

Step-by-step explanation:

First use sine to figure out x

so "sin(31) = 12 ÷ x"

mulitply both sides by x and you get "x * sin(31) = 12"

divide both side by sin(31) so you get "x = 12 ÷ sin(31)"

after plugging it in a calculator, you get 23.2992 and just rounf to the nearest tenth and you get 23.3
