The temperature of a city changed by -12 degrees celsius over a 2 week period. The temperature changed by the sum amount each week. Part A write an expresstion

T = S - 6n

Step-by-step explanation:

Let T be the temperature of the city after 'n' weeks, and let S be the starting temperature of the city.

If the temperature change is the same each week, the average change per week is given by:

The expression that describes temperature as a function of the number of weeks is:

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
