Answer:
The equation for the relationship between the weight and number of months is 
Step-by-step explanation:
we know that
A linear equation in slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept (value of y when the value of x is equal to zero)
or say b is the actual weight of the wrestler.
In this problem
m=5.5 kg/month
Let
W ⇒ the sumo wrestler's weight in kg (dependent variable)
t ⇒ the time in months (independent variable)
The linear equation is equal to

where
b is the actual weight when he started the diet.
Now Given
W = 140 kg
t = 11 months
substitute in the linear equation to find the value of b


Hence,The equation for the relationship between the weight and number of months is 
Basically you have to solve for the value of Y when x= 4
So you have -5y= 11 - 2x
y = -11/5 + 2/5x
therefore when x = 4 , y = -3/5
Answer:
it might be c I'm not to sure tho
Answer:
Education –> Mortality –> Fertility rates
Education –> Fertility rates
Step-by-step explanation:
Education and fertility is a key role to grow a large population. But if the mortality rate is low families tend to have less children.
Answer:
geometric sequence
Step-by-step explanation:
A geometric sequence is a sequence of numbers that is ordered with a specific pattern. Each successive number is the product of the previous number and a constant. The constant is the same for every term in the sequence and is called the common ratio.
