Answer:
y = 36x
Step-by-step explanation:
Given that x and y vary directly then the equation relating the is
y = kx ← k is the constant of variation
To find k use the condition x =
, y = 12, then
k =
=
= 12 × 3 = 36
y = 36x ← equation of variation
Answer:
combine -3-1
![- 2x - 14 = - 4](https://tex.z-dn.net/?f=%20-%202x%20-%2014%20%3D%20%20-%204)
if you want to solve for x then you would move the -14 to the left buy adding 14 to both sides.
![- 2x - 14 = - 4 \\ \: \: \: \: \: \: \: \: \: \: \: + 14 \: \: + 14](https://tex.z-dn.net/?f=%20-%202x%20-%2014%20%3D%20%20-%204%20%5C%5C%20%20%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%2B%2014%20%5C%3A%20%20%5C%3A%20%20%2B%2014)
your equation there will be
![- 2x = 10](https://tex.z-dn.net/?f=%20-%202x%20%3D%2010)
then you will divide -2 on both sides
![\frac{ - 2x}{ - 2} = \frac{10}{ - 2}](https://tex.z-dn.net/?f=%20%20%5Cfrac%7B%20-%202x%7D%7B%20-%202%7D%20%20%3D%20%20%5Cfrac%7B10%7D%7B%20-%202%7D%20)
finally x will equal
![x = - 5](https://tex.z-dn.net/?f=x%20%3D%20%20-%205)
Answer:
y=4x+9
Step-by-step explanation:
replace m with 4, which is the slope you gave, and
replace b with 9, the y-intercept you gave,
in the equation y=mx+b.
