Answer:
6 and -6
Step-by-step explanation:
3+2=5
<span>V (sale value) = $ 132000
P (profit) = 10% on the sale, ie 10/100 * 132000 = 1320000/100 = $ 13200
C (cost) = ?
As:
V = C + P
132000 = C + 13200
C = 132000-13200
C = 118800
Answer:
He paid $ 118800 for the house (</span><span>Purchase price of house)</span>
Answer:
(x, y) = (4, -2)
Step-by-step explanation:
The coefficient of y in the second equation is double the coefficient of y in the first. We can subtract twice the first equation from the second to eliminate y.
(3x +4) -2(x +2y) = (4) -2(0)
x = 4 . . . . . . . . . simplify
Substituting into the first equation, we have ...
4 +2y = 0
2 +y = 0 . . . . . . divide by 2
y = -2 . . . . . . . . subtract 2
The solution is (x, y) = (4, -2).
Answer:
B. 3x^2 - 2x - 1.
Step-by-step explanation:
(f + g)x = f(x) + g(x)
= -4x + 3 + 3x^2 + 2x - 4
Adding like terms we get the answer:
= 3x^2 - 2x - 1.
Answer:
x is 4.
Step-by-step explanation:
8 times 8 is 64
64 minus 4 is 60
60 divided by 15 is 4
