Answer:
The price of a game is 
Step-by-step explanation:
Let
x ----> the list price of a game
Remember that
To find out the price of a game that's been discounted 18% off its list price, multiply the list price by the number 0.82
so
T is equal to any number just choose one. In the end they both end up with t+1. I hope my answer is correct and sorry for my handwriting.
Answer:
It represents polynomial expression
Answer:
5
Step-by-step explanation:
SQ= 10
SO is half way so divide by 2
We will assume that we have a function relating between the time and the temperature. Any point in this function can be expressed as (x,y) where x is the time and y is the temperature (any point is expressed as (time, temperature)).
We have two points given:
<span>At 7 p.m. the temperature is 72 degrees F: First point is (7,72)
</span><span>At 10 p.m. the temperature is 52 degrees F: Second point is (10,52)
The rate of change is simply the slope of this function, this slope can be calculated as:
rate of change = (y2-y1) / (x2-x2)
we have y2= 52, y1= 72, x2= 10 and x1= 7
Substituting in the equation, we can calculate the rate of change as follows:
rate of change = (52-72) / (10-7) = -6.667 degrees/hours
Note: The negative sign indicated a DECREASE in the temperature.</span>
