This isn't math but okay. The independent variable is what you CHANGE, the dependent variable is what you MEASURE. (you can change/tweak any of my answers as you please)
1. DV = amount of noise in the room
IV = the number of speakers
2. DV = the rate of cooling of a glass of water
IV = amount of ice
3. DV = amount of sunlight absorbed
IV = color of clothing
4. DV = the force needed to lift the block
IV = weight of the block
5. DV = amount of space needed to store the object
IV = volume of an object
6. DV = time needed to cook something
IV = temperature of the grill
7. DV = sweetness of the baked cookies
IV = amount of sugar in the mix
8. DV = amount of force needed to break the rope
IV = thickness of rope
9. DV = volume of water traveling down the river
IV = amount of rain
10. DV = softness of the ground
IV = amount of rain
11. DV = amount of space needed
IV = temperature of a substance
Answer: D
To show work is plug the the x-coordinates for the points given.
Example:
x=2
y=-(1/4)x^2
y=-(1/4)2^2
y=-(1/4)4
y=-1
If you would like further explain action feel free to ask. :)
Answer:
The measures of the angles are 50° and 130°
Step-by-step explanation:
Let
x ----> the measure of one angle
y ----> the measure of the other angle
we know that
If two angles form a linear pair , then their sum is equal to 180 degrees
-----> equation A
----> equation B
substitute equation B in equation A
solve for y
Find the value of x
The measures of the angles are 50° and 130°
Y= -15
That would be the y-intercept, I hope this helps
