A. The data in the table represent a function. y=x/2. This is seen as for every value of x in the table, y=x/2(half of it). You can show this further by trying this fact on each value.
B. For the original function, when x =8, y=x/2=4
For the function given in this part, when x=8, y=3(8)-10
y=24-10 y=14
This means the relation given in this part has a greater value when x=8
C. When x=80, f(x)=3(80)-10
=240-10
=230
The only value for x to make tanx = 0 is either 0 or 180 or 0 or pi.
Answer:
y=x-5/2
Step-by-step explanation:
Swap y and x
x=2y+5
since a function has to be in the form y=mx+c
take 5 to the other side in order to remain with 2y then divide both sides by 2
x-5/2=y
y=x-5/2
The relation is not a function because the value 3 in the domain is paired with two different values in the range.
Good luck!!!
Answer:
44, 45, and 46
Step-by-step explanation:
135-(x+1)=x+(x+2)
135-(x+1)=2x+2
135=3x+3
132=3x
x=44
So the first number is 44
Then just add 1 and 2 to get 45 and 46 as the second and third number.
