Is the rate of change of the function 5? Yes, because y changes by 5 every time x changes by 1.
Yes, because y changes by 1 every time x changes by 5.
No, because y does not change by 5 every time x changes by 1.
No, because y does not change by 1 every time x changes by 5.

No, because y does not change by 5 every time x changes by 1.

Step-by-step explanation:

If the rate of change was 5 the line on the graph would clearly be on a grid point. Since the line is not exactly on a grid point for some coordinates we cannot determine if the rate of change is 5. So we will go with option 3

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
