Hey there!
y = -1/4x + 10
Looking for the amount of hours of sleep for an 8 year old, so x is 8.
Solve for y:
y = -1/4(8) + 10
y = -2 + 10
y = 8
The predicted number of average hours of sleep for an 8 year old is 3. 8 hours.
Hope this helps!
Answer:
-3x>24
Step-by-step explanation:
-3x-10>14
now we add 10 to both sides, 10+14 is 24
so, the missing step is -3x>24
Answer:
f(y) = y(y - 4).
Step-by-step explanation:
The function has two x-intercepts of the function are (0,0) and (4,0).
X-intercept means that the y-value will be zero.
Therefore, the function f(y) has two roots, one at y = 0 and another at y = 4.
Hence, the function x = f(y) has two factors (y - 0) and (y - 4)
So, the function is f(y) = (y - 0)(y - 4) = y(y - 4). (Answer)
