3/4n -18= 1/4n -4
⇒ 3/4n -1/4n= -4+18
⇒ 2/4n= 14
⇒ 1/2n= 14
⇒ n= 14/(1/2)
⇒ n= 14* (2/1)
⇒ n= 28
Final answer: n= 28~
Answer:
table a
Step-by-step explanation:
To be a function, every x has to have exactly one y. In table b the x value 5 has an output of 2 and 6 and therefore, since it has more than one y it is not a function. In table D the x value 6 has a y output of 7 and 2. Therefore it is not a function. In table A every x has exactly one y.
3.Slope: 10 Y int: 5
4. Slope: 5 Y int: 10
6.Slope: 1/3 Y int: 3.5
7.Slope: 4/3 Y int: -1
8.Slope: 2/-4 Y int: -1
The way you do this is the Y int is where the line crosses through the y-axis. Finding the slope is finding the rise over run (y/x). It's easy to find when you know how to.
Use 4. as an example. Start where at (-3,-5) or (-2,0). Each 'rise' up 5 and 'runs' one block over, giving you the slope of 5/1 or 5 simplified.
7 is harder, but start at (-3,-5). It 'rises' up 4, then 'runs' 3, also giving you the y int, as it crosses the axis. As the rise is 4 and run is 3, it creates the slope 4/3.
Answer:
This is a linear graph.
Step-by-step explanation:
Since the x values increase at a constant of 1. The y-values have a 1st difference of -4 which means the graph is linear.
Answer:
108 minutes
Step-by-step explanation:
because 45/5=9 and 180/20=9 so multiply 12 by 9 12x9=108
