Answer:
7,600
Step-by-step explanation:
both parents invest 7,600.
7,600x2= 15,200
there are 2 girls so divide 15,200 by 2 and u get 7,600
Answer: it is a direct variation.
Justification:
In a direct variation the variables are related by a proportionality constant in this way:
y = k x
Tthan means that the value of y is always the product of a constant times the value of x.
The situation discribed for the coal may be written as:
number of tons of coal burned: c
number of hours: h
⇒ c = k × h
Which is that you can calcualte the number of tons of coal burned at any time, once you know the proportionality constant k.
The answer is -12
these are the steps on how to find that
-2x2y
-2(-3)2(y)
6 times -2
-12
4✔️12x
4✔️4 • 3x
4 • 2 ✔️3x
8✔️3x
This is the solution.
