Answer:
8, 2, - 9, - 7
Step-by-step explanation:
The domain is the first coordinate of an ordered pair. This means that the domain is going to be x. In this set of ordered pairs, the domain is 8, 5, - 9, - 7.

The answer is 139 cubic yards
This mulch will be of cylindrical shape.
The volume (V) of a cylinder is:
V = l · w · h (l - length, w - width, h - height (in our example, height = depth)
It is known:
l = 125 feet
w = 60 feet
h = 6 inches = 0.5 feet
V = l · w · h = 125 · 60 · 0.5 = 3750 feet³
Since 1 cubic foot is 0.037 cubic yards, 3750 cubic feet are 139 cubic yards:
0.037 · 3750 feet³ = 138.75 cubic yards ≈ 139 cubic yards

Answer:
(-6.5, -5)
Step-by-step explanation:
The first point is weighted by the length of the second segment, and vice versa.
P = (3A +1B)/(3+1)
P = (3(-7, -9) +(-5, 7))/4 = (-21-5, -27+7)/4 = (-6.5, -5)
- It is important to note that:
A nickel = $0.05
A dime = $0.10
We would be representing,
The number of nickels = n
The number of dimes = d
- Kendra has $3.15 in dimes and nickels. Writing this statement as an algebraic expression:
0.05n + 0.10d = 3.15...............Equation 1
- She has 4 times as many dimes as nickels. The algebraic expression for this statement :
4n = d ........................................ Equation 2
We would substitute 4n for d in Equation 1
0.05n + 0.10 x 4n = 3.15...............Equation 3
0.05n + 0.4n = 3.15
0.45n = 3.15
Divide both sides by 0.45
0.45n/0.45 = 3.15/0.45
n = 7
The number of nickels is 7
We solve for d, the number of dimes
4n = d
n = 7
4 x 7 = d
28 = d
The number of dimes is 28
Therefore, Kendra has 7 nickels and 28 dimes
