Answer:
34.12
Step-by-step explanation:
X+y+z=22
(x+y+z+t)/4=8
subsitute
x+y+z=22
(22+t)/4=8
multiplly by 4
22+t=32
subtract 22
t=10
the fourth number is 10
Answer:
D. y ≥ 0
Step-by-step explanation:
The range of the function refers to the possible y values which come under the limits of the function.
Here, we can see that no y values are less than 0.
Hence, the range of the function is :
D. y ≥ 0
Answer:
see below (upper left)
Step-by-step explanation:
When the x-values are sequential, a linear function will have y-values that differ by the same amount.
The upper left table has y-values that differ by -2.
The upper right table has y-values that differ by 2, -6, 2. These values are not the same.
The lower left table has y-values that differ by -1, 5, -13. These values are not the same.
The lower right table has y-values that differ by 1, 3, 5. These values are not the same.*
__
The upper left table represents a linear function.
_____
* The <em>2nd</em> differences are a constant 2, so this table represents a <em>2nd</em>-degree polynomial.
