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
Now we plug in 2/3 for k
Given x=-0.5 and find out y
y=-0.33
the value of y is -0.33 when x=-0.5
Step-by-step explanation:
Thus first option is the correct answer.
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
Answer: =12
Step-by-step explanation: Hope this help :D
