Answer:
The expression is (-24) / 6 = -4degrees which means that in each week the average change in temperature was -4 degrees Celsius.
Step-by-step explanation:
Change in a quantities can as well be interpreted as rate of change which is used in many everyday problems, such as weather forecast, traveling , in science and so on.When we are talking about rate of change it's is usually in ratio such as Miles per hour or feet per second can be used in calculation involving rates of speed. It is how one quality is changing with respect to time , for instance, rate equals distance divided by time: r = d/t.
In finance rate of change is also applicable we can have Unit price which is a particular rate that compares a price to some unit of measure. Example is $64 per dozen.
Therefore, Given from the question,
The temperature of a city changed -24 degrees Celsius ,
Time =6 weeks period.
Then change is r = d/t.
= (-24) / 6
Change = (-24) / 6 = -4 degrees
This means that each week the average change in temperature was -4 degrees Celsius.
Consecutive exterior angles
Answer:
y ≥ 2
x ≥ -1
y ≤ -x+6
Step-by-step explanation:
The solid line means ≤ or ≥
The dashed line means < or >
y ≥ 2
x ≥ -1
y ≤ -x+6
We need to FOIL that out and then get it into standard form to see what our A, B, and C are. FOILing gives us
. If we move the 7 over by subtraction and set it equal to 0, we have
. In order to avoid a negative leading coefficient, we can change all the signs to get
so A = 1, B = 0, C = -18, first choice above.
Step-by-step explanation:
Yes. Percent of change is the amount of change divided by the initial value.
% of change = (final − initial) / initial × 100%
If the change is greater than the initial value, then the percent change is greater than 100%.
For example, if the price of something triples from $1 to $3, the percent of change is:
% of change = (3 − 1) / 1 × 100%
% of change = 200%
