Answer:
The solution set of a disjunction is the union of the solution sets of the individual inequalities. A convenient way to graph a disjunction is to graph each individual inequality above the number line, then move them both onto the actual number line

Answer:
120 deg Unknown = 100 deg Celsius since we know that the ice point is at
0 deg Celsius and the steam point is 100 deg Celsius
So you have 1.2 deg U / 1 deg C
70 deg U / (1.2 deg U / 1 deg c) = 58.3 deg C (temperature in deg Celsius)
Or 58.3deg C * 1.2 deg U / 1 deg C = 70 deg U
Answer:
This is the definition of slope.
Step-by-step explanation:
The formula for slope is:
m(slope) = (y2 - y1)/(x2 - x1)
This shows the difference in y, which is rise, divided by the different in x, or run.
