Answer:
k = 7
Step-by-step explanation:
given y varies jointly with x and w then the equation relating them is
y = kxw ← k is the constant of variation
to find k use the condition when y = - 42, x = 2 and w = - 3 , then
- 42 = k × 2 × - 3
- 42 = - 6k ( divide both sides by - 6 )
7 = k
constant of variation is k = 7

Step-by-step explanation:
i just need points lol
You have to leave Y by itself in one side. To do that, you need to subtract 2x from both sides. You're now left with -3y = 8-2x. Last step is that you divide 3y, 8, and -2 by -3.
Good luck :)
12.6 million = 4p + 1 million
to solve:
12.6 million - 1 million = 4p + 1 million - 1 million
11.6 million/4 = 4p/4
2.9 million = p
the population in 1950 was approximately 2.6 million
