Answer:
Two negatives together get a positive
Step-by-step explanation:
-9-(-4)
-(-4)
+4
So first we find the change
45 to 15=45-15=30
change is 30
rate of change=(change)/(original)
original=45
change=30
30/45=10/15=2/3=0.66666666=66%
rate of change is 66.66%
Answer:
5.781 inches.
Step-by-step explanation:
Since Mr. Jimerson records the amount of snowfall that the local area recieves, recording the following data: 12 am-1am: 0.3 inches | 1 am-2am: 0.8 inches | 2 am-3am: 1.36 inches | 3 am-4am: 2.019, if the total amount of snowfall at 7am is 7.8 inches, to determine how much snow fell between 4 am-7am the following calculation must be performed:
7.8 - 2.019 = X
5.781 = X
Therefore, since the amount of snow accumulated at 7 am was 7.8 inches, the snowfall between 4 and 7 am was 5.781 inches.
KX = x+4 so solve for k.
Divide both sides of the equation by x and you get K=4.
Plug it in, and you get (4)(7)=28
Your answer is 28.
