The equation of a line that is perpendicular to -9x = 15 - 3y is y = -1/3(x) + c.
Given:
-9x = 15 - 3y
3y = 15+9x
divide by 3 on both sides
3y/3 = 15/3 + 9x/3
y = 3x + 5
m = 3
Perpendicular slope m1 = -1/m
= -1/3
substitute m value in y = m1x +c
y = -1/3(x) + c.
Therefore the equation of a line that is perpendicular to -9x = 15 - 3y is y = -1/3(x) + c.

Answer:
450 ml.
Step-by-step explanation:
Let x be the amount of water drank by Alla and y be the amount of water drank by Balla.
We have been given that Alla and Balla together drink 750 ML of water. We can represent this information as:
We are also told that Alla drinks 50% more than Balla. We can represent this information as:
From equation (1) we will get,
Upon substituting this value in equation (2) we will get,
Upon distributing 1.5 to right hand side of the equation we will get,
Upon adding 1.5x to both sides of equation we will get,
Let us divide both sides of our equation by 2.5.
Therefore, Alla drank 450 ml of water.
Answer: 15850
Step-by-step explanation:
if johns account has 10000 dollars then each year he'll be making at 3.25% interest that's a total of $325 each year therefore in 18 years he'll have made 325 X the 18 years which you turn hall to 5850 as interest but now the question is it asking how much will John have in his account after 18 years at the yearly simple interest of the 3.25 there for the total will be 15850 dollars
Answer:
1)y=2x+7
2) unsure what the question is due to blur
3)y=3/4x-2
4)y=-2x
