Answer:

The equation is y=-4x+103

The slope is m=-4

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

y is the amount left in the saving account

x is the number of weeks

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The slope is equal to

m=-\$4\ per\ week --> is negative because is a decreasing function

The y-intercept or initial value is

b=\$103

substitute

y=-4x+103

A baby was born 3/4 of a month early. At birth its weight was 7/8 kilograms, which is 9/10 kilograms less than the average weigh
BlackZzzverrR [31]

Answer:

The average weight of a newborn otter is 1.775 kg.      

Step-by-step explanation:

We are given the following in the question:

Weight of newborn otter =

\dfrac{7}{8}\text{ kg}

Let x lg be the average weight of a newborn otter.

Thus, we are given the relation:

\dfrac{7}{8} = x - \dfrac{9}{10}\\\\x = \dfrac{7}{8} + \dfrac{9}{10}\\\\x = \dfrac{35+36}{40} = \dfrac{71}{40}\\\\x = 1.775\text{ kg}

Thus, the average weight of a newborn otter is 1.775 kg.
