<u>Answer:</u>
-17°F
<u>Step-by-step explanation:</u>
Rate of change is the rate which tells how one quantity changes in relation to another quantity. It is also known as the slope.
To find the rate of change in the temperature, we can use this formula:
Rate of change =
Rate of change =
Rate of change =
Therefore, the temperature changes by -17°F per minute where the negative sign indicates the drop in temperature per minute.
25% of 60is 15
70% of 30 is 21
What % Is 15 of 50= 7.5
15% of 50 is 7.5
15% of 40 is 6
40% of 30 is 12
40% of 50 is 20
A linear function represents a line, a quadratic function represents a parabola.
The dots fit a parabolic behaviour (they are descendent at the beginning, they reach a minimum and then start growing again), so a quadratic model could fit the dots much better than a linear one.
Answer: no solution
Step-by-step explanation: after simplifying they are parallel which means they have no solutions
