Answer:
k = -2
Step-by-step explanation:
x -1 0 2 5
f(x) 2 0 -4 -10
ƒ(x) = kx
Substitute a pair of values for x and ƒ(x)
-10 = k×5
Divide each side by 5
k = -2
The constant of variation k = -2.
Your answer would be 5.01 because to round to the hundredths means two decimal points meaning 5.014. The 4 is not more than 5 so it wouldn’t make the 1 move up. So it stays 5.01.
Answer:
The range of the graph is [-10, 10]
Step-by-step explanation:
This represents how the y-values of the graph range from -10 to 10.
Because there are no arrow marks on the ends of the graph, we know that the graph stops there at -10 and 10 and doesn't go beyond that.
Simple,
writing an equation to find the sides,
x+2+x+2+x+x=44
4x+4=44
Subtract 4 from both sides, making the equation look like this,
4x=40
Divide by 4
x=10.
To check it, just plug it back into original equation.
10+2+10+2+10+10=44
It works. :)
