When Nathan went to bed, the outside temperature was 28°F. When he woke up the next morning, the temperature had decreased to -13°F. By how many degrees did the temperature change during the overnight hours?

Step-by-step explanation:

Given that the initial temperature outside was  28°F before Nathan went to bed, to solve for the amount the temperature decreased, we need to understand that it first decreased from 28°F to  0°F first before it went down to  -13°F

Hence from  28°F-  0°F --- it has decreased by  28°F

Also from  0°F- 13°F--- it has decreased by 13°F

Therefore in total it decreased by ( 28°F+ 13°F)=  41°F

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
