Answer:
1) 1/4
2) 3/5
Step-by-step explanation:
1) The rate of change is basically the slope, and you can find the slope by doing:
change in y/change in x
I started with the point (0,-2) because it's on the line
It goes up 1 and left 4 to get to the second point on the line
So change in y/change in x = 1/4 (this is the rate of change)
2) This is basically the same thing, but you need to do some subtraction.
Change in y = -9-(-3) = -6
Change in x = -5 - 5 = -10
Change in y/change in x = 3/5 (this is the slope or rate of change)
Answer:
+ 6x + 5
Step-by-step explanation:
5x + x = 6x
4 + 1 = 5
x to the power of two is x squared which equals 
Try to visualize the situation; "A percent multiplied by $45 will be me $27"
$45(x/100)=$27
x/100=27/45
x/100=0.6
x=60%
Therefore, the discount was 60%
