<em>Independent variables are variables of a quantity that are not affected by any conditions. </em>
<em>Dependent variables are variables of a quantity that change if conditions relative to that variable changes.</em>
For example, we generally we take x as independent variable by x variable and dependent variable by y variable.
To find the rate of change we get two values of independent variable (x's) and two values of dependent variables (y's) to get two coordinates in form of
(x,1,y1) and (x2,y2).
<h3>And we can find the rate of change by applying slope formula</h3>

Answer:
about 1.5 pounds
Step-by-step explanation:
The moon's gravity is about 1/6 that of Earth, so a 9-lb cat would weigh about 9/6 = 1.5 pounds on the moon.
We can represent this situation by the equation 2x+4x+5x=33.
Then 11x=33, and x = 3.
Then the children's ages are in the ratio 2x:4x:5x, or 2(3):4(3):5(3), or
6:12:15.
Do these 3 ages add up to 33? 6 + 12 + 15 = 33? YES!
The children's ages are 6, 12 and 15 years respectively.
Answer:
3.6 hours
Step-by-step explanation:
Blake can do work in hours = 9
Blake can do a part of work in 1 hour = 
Ned can paint the same room in six hours.
Ned can do a part of work in 1 hour = 
They can do a part of work together in 1 hour = 
= 
Now they can do part of work in hour = 1
So, they can do whole work in hours = 
= 
Hence it will take 3.6 hours to paint the room if they work together.
Answer:3
Step-by-step explanation:
Simply plug in -1 for anywhere you see x in the equation so...
8(-1)^2-5
8(1)-5
8-5
3
