Direct Variation
If y varies directly with x, then they are related by the equation:
y = kx
Where k is a constant called the proportionality factor.
It's given that y = -38 when x = 19. Substituting those values in the equation, we can find the value of k:
-38 = k*19
Dividing by 19:
k = -38 / 19
k = -2
Now our model is complete:
y = -2x
Now it's required to find the value of x when y = -4. Substituting:
-4 = -2x
Dividing by -2:
x = -4 / (-2)
x = 2
Answer:
90 cm^3
Step-by-step explanation:
The equation to solve for the volume of rectangular prisms is l×w×h or length×width×height
5×3×6 is 90cm^3
F(x) - g(x) = 3x + 2 - (6x-7) = 3x + 2 - 6x + 7 = -3x + 9;

Answer:
V=19.9*(0.9144m)^3=15,2146416738816 m^3
On their farm, Adam’s family maintains a storage that can hold 18.0 cubic yards (yd3) of grain. Use the fact that 1 yard is approximately equal to 0.9144 m to convert this volume to m3. Round your answer to the nearest hundredth. Do not type the units in the space below.
Step-by-step explanation:
1 yard =0.9144 m
We will take the 18.0 cubic yards, cross multiply with 0.9144 and then divide the result by one to get
13.76m3
Answer:
I'm pretty sure it's 1 cup of water
You need 2 cups of pancake mix more than water so if you have 3 cups of pancake mix then you'd need 1 cup of water.
6 cups of mix = 4 cups of water
the cups of the mix is are 2 more cups than the water
3 cups of mix = 1 cup of water
I hope that helps and good luck! :)
