F(14) would be, 14=1/2x-2
Answer:
Yes, all three of them are proportional
Step-by-step explanation:
First, let's simplify them all the way:
10/45 = 2/9
20/90 = 2/9
6/27 = 2/9
All three of these ratios simplified down to their simplest form are 2/9, meaning that they are all proportional.
Answer:
No he is not correct. As the answer would be -2/5 = -0.4 and 5/-2 = -2.5 as the answer is also not opposite.
Answer:
the last one
Step-by-step explanation:
Two lines will be parallel when their slopes are equal, and two lines will be perpendicular when their slopes are negative reciprocals of each other. Our slopes for these two equations are the coefficient for the x value. Both slopes are equal so these lines are parallel.
The formula for converting Fahrenheit to Celsius is:
~Multiply by 1.8 (or 9/5) and add 32.
