Well for the first one you have to subtract 3 on both sides so that would make the equation x > -8 (because a negative subtracting a positive is basically a negative plus negative) and so your equations done. For the second one you divide both ides by -4 so your equation would be x < 4 (the sign would be less then or qual to because you divided by a negative)
B. Communitive property of addition
Using the equation y=6x+12, where x is the number of hours and y is the total cost for the given value of x, you can plug in 42 for y and solve:
42=6x+12
42-12=6x
30/6=x
5=x
Thus, Amy can rent the bike for 5 hours.
Answer:
Step-by-step explanation:
Hello!
The variable of interest is the weight in ounces of a soap bar.
Attached is a QQplot diagram.
A Q-Q plot is a diagram that compares two probability distributions, in this case, the probability distribution of the data set against the theoretical normal distribution. If the observed data matches the theoretical sets, you can say that that population follows said distribution.
As you can see in the graphic the observed values (blue dots) fit the normal theoretical quantiles, so we can say that the data appear to come from a normal distribution.
I hope it helps.
