Part (a)
Independent variable = age
Dependent variable = height
"depends on age" indicates that age is independent.
-----------------------------------
Part (b)
Independent variable = amount of sleep
Dependent variable = mood
The key word is "determines". The stuff before this word is the independent variable which affects the dependent variable.
-----------------------------------
Part (c)
Independent variable = time water has been running
dependent variable = amount of water in the tub
Time is usually the independent variable
-----------------------------------
Part (d)
Independent variable = speed
dependent variable = distance from home
-----------------------------------
Part (e)
Independent variable = amount of homework done
dependent variable = speed
This seems like an odd pairing of homework and speed. Could there be a typo? I noticed that part (f) is very similar
-----------------------------------
Part (f)
Independent variable = amount of hw that is assigned
dependent variable = amount of homework done
Like with part (a), the stuff before "depends" is the dependent variable
Answer:
Step-by-step explanation:
(1,2) ; (3,2)
slope = y₂ - y₁ / x₂ - x₁
= ( 2-2 )/( 3 - 1) = 0
So, the line is parallel to x-axis and its slope is 0
-40 degrees i think im not sure
Answer:
y=-4x+9
Step-by-step explanation:
y-y1=m(x-x1)
y-(-3)=-4(x-3)
y+3=-4(x-3)
y=-4x+12-3
y=-4x+9
Answer:
9
Step-by-step explanation:
3^4= 81
3^2= 9
81/9=9
hope this helped!!!! :)
