Y = kx
the question ask for "direct vation"...the formula must always to be y at the left side and k at the right side
Answer:
The answer is y=3x+2
Step-by-step explanation:
y-y=m(x-x¹)
y-5=3(x-1)
y-5=3x-3
+5 +5
y=3x+2
An equation is said to have a constant of proportionality if 'x' is a multiple of 'y' or 'y' is a multiple of 'x'.
Now, we have to determine an equation with constant of proportionality as '1'.
1.
This equation has constant of proportionality as '
'.
2.
This equation has constant of proportionality as '
'.
3.
This equation has constant of proportionality as '
'.
4.
This equation has constant of proportionality as '1'.
Option D is the correct answer.
The coefficient of x in the equation is 1/(300 grams). Multiply by the reciprocal of that, which is (300 grams).
x = (300 grams)×(2 grams)/(100 grams) = (300×2/100) grams = 6 grams
_____
This is the way you solve any equation where x is multiplied by some value in the only term on one side of the equal sign.
Answer: Mark up percent = 20%
Step-by-step explanation:
Given: Cost price of each T-shirt = $5.00
Amount required = $450
Total students = 75
Market price for each T-shirt to raise the required amount = (Amount required ) ÷ 75
= $450 ÷ 75
= $ 6
Mark up percent = 

Hence, Mark up percent = 20%
