6y=12x+18
Step-by-step explanation:
Y=Mx+b
Answer:
d. 40 units
Step-by-step explanation:
The length of the horizontal side of this rectangle on the line y=20 is the difference of the x-coordinates, 12 and 20, so is 8. The length of the vertical side on the line x=20 is the difference of the y-coordinates, 20 and 8, so is 12.
Two sides are of length 8 and two are of length 12. The perimeter is the sum of the side lengths, so is ...
P = 2·8 +2·12 = 40 . . . units
142 is the sum of 64 + 78
Answer:
X = -1/2 or 1/2
Step-by-step explanation:
When the square root of a number is found, this usually results in 2 solutions which may be equal in size but opposite in signs.
As such,
X^2=1 to find x find the root of both sides
X = √1
X = -1 or 1
Going by this
4x^2=1
Divide both sides by 4
X^2=1 /4
taking the square root of both sides
X = √1/4
The root of 1 is -1 or 1 while that of 4 is -2 or 2 hence,
X = -1/2 or 1/2

Solution:
So he got a 20% profit on $1.20.
20% of 1.20 → 0.2 x 1.20 → 0.24
Same thing goes with 20% loss.
20% of 1.20 → 0.2 x 1.20 → 0.24
-----------------------------------------------
Answer:
On the sale of the pipes, he gained a profit of $0.24 and lost a profit of $0.24, so the sale is (a) broke even.
