For something to be a function, an input (x value) can only have ONE output (y value)
For example:
(2 ,4)
(2, 5) This is not a function because the input has multiple outputs.
So your answer is the 1st option
Answer:
20-25
Step-by-step explanation:
i think but not sure
Answer:
3 = 95, 4 = 85, if a and b are parallel
Step-by-step explanation:
To find which point is NOT on the line y = 5x + 1, we just need to plug each point into equation y=5x+1 to see which one point satisfies this equation.
check for (1,6)
y=5x+1
or 6=5*1+1
or 6=5+1
or 6=6
Which is TRUE.
--------
check for (2,11)
y=5x+1
or 11=5*2+1
or 11=10+1
or 11=11
Which is TRUE.
--------
check for (0,1)
y=5x+1
or 1=5*0+1
or 1=0+1
or 1=1
Which is TRUE.
--------
check for (-1,6)
y=5x+1
or 6=5*(-1)+1
or 6=-5+1
or 6=-4
Which is FALSE.
--------
Since only point (-1,6) fails to satisfy the given equation hence point (-1,6) is the final answer.
Hello!
You have to find out how many cubes are in 1 layer
You do this by multiplying the amount across by the amount along the side.
12 * 6 = 72
Divide this by the amount of cubes
288 / 72 = 4
There are 4 layers
The answer is 4
Hope this helps!
