Given that we have the change in temperature over 7 hours and we are looking for the change over 1 hour, we can divide the total change in temperature by 7. Thus, the change in temperature would be
.
Additionally, this can be solved by equations:




By using two different methods, we can determine that the change each hour was equal to 42/7 C° per hour.
ANSWER
No solution
EXPLANATION
The first equation is

and the second equation is

We equate the two equations to obtain;

This implies that


There is no real number whose square is -1.
Therefore, the equation has no solution.
The correct answer is
<span>D. The number of degrees in its supplement
The size of the sides and the rotation is irrelevant and would still keep the angle having the same size. The number of degrees in the supplement decides how big an angle is because the larger the supplementary angle the smaller the angle we're observing will be, and vice versa.</span>

Answer:
<u>Given:</u>
- 2x + 9 < 0 ⇒ 2x < - 9 ⇒ x < - 4.5
- x > -12
<u>Combined we have:</u>
<u>The integers in the same interval are:</u>
- x ∈ {-11, -10, -9, -8, -7, -6, -5}
