Answer:
110.30
Step-by-step explanation:
125.99-(125.99X0.15)= 107.09
107.09+(107.09X0.03)= 110.30
So, first step is to find the y=mx+b equation.
First we find the slope. Slope is equal to change in y divided by change in x.
3 - -2 = 3 + 2 = 5 = 1
4 - -6 = 4 + 6 = 10 = 2
So our slope is 1/2, or .5 y=.5x+b
Now we plug a point in to our new equation to find B.
-6 = .5*-2 + b
-6 = -1 + b
b = -5
So, D is wrong because the y-intercept is -5 ^_^ Hope I helped!
Let <em>S</em> denote the sum
We can condense this to sigma notation:
Expand the summand:
Recall the Faulhaber formulas,
So we have
Answer:
You would need 9/4 or 2 1/4 gallons of paint
Step-by-step explanation:
You would need 2 1/4 gallon of paint because if 1/3 of the room takes 1/4 paint, then 3/4 would finish a room, multiply the three by three for three rooms and there you have 9/4 or 2 1/4 gallons
