Answer:
3.514 degrees per hour
Step-by-step explanation:
To find change per hour, you find the slope, which is change in output (temperature) over change in input (hours)
y2-y1 / x2-x1
-12.3 - 0 / 3.5
3.514 degrees per hour
F(-3) means when x = -3
Find the value on the graph
Solution: f(-3) = 6
F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300
f(120) = (20 * 120) + 300 = 2400 + 300 = 2700
Answer:
Step-by-step explanation:
<u>Distance Between two Points in the Plane</u>
Given two points A(x,y) and B(w,z), the distance between them is:
We are given the points (5, 14) and (−3, −9). Substituting into the formula:
Answer: x>-2
Step-by-step explanation:
To find the values of the inequality, you treat this like it would be any other equation.
