I'm assuming your function is f(x) = -9^(x+1)
So we just have to plug in and see if the function is true.
1) -9^(0+1) = -9^1 = -9
YES
2) -9^(1+1) = -9^2 = -81
NO
3) -9^(-1+1) = -9^0 = -1
YES
3500 miles divided by 175 Miles Per Hour. 3500/175=20 Hours.
3.5 hours: $10 because if a 1/2 hour equaled 1.25 : 3.5 hours would give you $7.75
Answer:
37.7 inches
Step-by-step explanation:
V=πr^2h
Is the formula for the volume of a cylinder
^2 is exponent 2
r is the radius (2) and h is the height (3)
1.Identify the fractions. Using the distributive property, you’ll eventually turn them into integers.
2.For all fractions, find the lowest common multiple (LCM) -- the smallest number that both denominators can fit neatly into. This will allow you to add fractions.
3.Multiply every term in the equation by the LCM.
4.Isolate variables adding or subtracting like terms on both sides of the equals sign.
5.Combine like terms.
6.Solve the equation and simplify, if needed.
