Answer: C: -2.5
Step-by-step explanation:
When looking at the graph we see that the temperature (y-axis) starts at 80 degrees. To find the slope, or how much it decreases and how often, we find the difference between 80 and the temperature it dropped to which is 77.5 . We also see it dropped this much after 1 hour which means each hour it drops -2.5 degrees so the correct answer is C.
Answer:
Step-by-step explanation:
The perimeter of a rhomboid: The perimeter of a rhomboid is the sum of all sides of the figure i.e. P= (a +b + a +b) = 2(a + b).
B is the base of the rhomboid and a is the length of the side of the rhomboid.

Answer:
C)
Step-by-step explanation:
options B and D are eliminated because their graphs do not intersect the y-axis at -1
If you input (0,0) - a random ordered pair picked from the shaded area - into the inequality for 'A' you can see if that is true or not
0 ≤ 0 - 1
0 ≤ -1 FALSE
If you input (-5,0) - a random ordered pair picked from the shaded area - into the inequality for 'C' you can see if that is true or not
0 ≤ -6/5 (-5) - 1
0 ≤ 6 - 1
0 ≤ 5 TRUE
