Answer:
Refractive index of a medium depends upon the refractive index of the surroundings
The number of glasses is restricted to 44 cups. So the number of iced tea cups and the number of lemonade cups that she can serve is, maximum, 44. Then, if you call x the number of glasses of iced tea and call y the number of glasses of lemonade, you have that the total number of glasses (cups) is x + y. And <span>the equation that represents the number of glasses that she cacn serve is x + y = 44. You can place it in other equivalent ways, for example, solve for y: y = 44 - x. Those two equations are valid answers because they represent the same equation.</span>
Answer: -3
-3(0)-1=-1
-3(-4)-1=11
-3(-6)-1=17

Answer:
x = 2
Step-by-step explanation:
First, distribute 6 to all terms within the parenthesis.
6(2x + 3) = 12x + 18
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
12x + 18 = 42
First, subtract 18 from both sides.
12x + 18 (-18) = 42 (-18)
12x = 24
Isolate the variable x. Divide 12 from both sides.
(12x)/12 = (24)/12
x = 24/12
x = 2
2 is your answer for x.
