Answer:
The relationship between two variables is decreasing and linear.
Step-by-step explanation:
From the given table it is notice that the function passing through the points (1,5), (2,-1), (3,-7) and (4,-13).
Slope of the function between first two points (1,5) and (2,-1) is

Slope of the function between last two points (3,-7) and (4,-13) is

The rate of change or slope of the function is constant.
From the given table it is noticed that the values of y decreased by 6 units as the values of x increased by 1 units.
Since the rate of change constant and negative, therefore the relationship between two variables is decreasing and linear.
Answer:
Sarah have
bottle of water.
Step-by-step explanation:
We are given that,
Total number of bottles = 5
As, each bottle is divided into 4 portions.
The amount of water per person = 
Further, Sarah took 1 portion from each bottle and there are 5 bottles.
So, the amount of water Sarah have =
= 
Hence, Sarah have
bottle of water.
Answer:
slope: 3 for N and 1/2 for O
Step-by-step explanation:
Answer:
Option c is right.
Step-by-step explanation:
Given is a parabola y =x^2
From that transformation is done to get parabola as
y =(0.2x)^2
We find that instead of x here we use 0.2x
i.e. New x = 5 times old x
Hence there is a horizontal expansion of scale factor 5.
We can check with any point also
When y =4, x=2 in the parent graph
But when y =4 , we have x = 10 in the new graph
i.e. there is a horizontal expansion of scale factor 5.
Answer:
m(x)= 0 when X= 3
Step-by-step explanation:
2*3=6
6-6=0
For (2x-6)
3-4=-1
So -1*0=0
it can also be look at like this (0,-1)
