Both have slope 4 and intercept 3 so they are coincident lines
Answer:
882 ft
Step-by-step explanation:
The transformation (x,y) --> (x,-y) is reflection over x axis. while the x coordinates in the image stay the same as the original, y coordinates change the sign.
Therefore coordinates of original image and final image after reflection
E - (0,3) --> E' (0,-3)
F - (2,2) --> F' (2,-2)
G - (1,1) --> G' (1,-1)
The diagram attached shows both the original image and image after reflection
X = shorts and y = socks
2x + 3y = 33
x + 5y = 27.....multiply by -2
------------
2x + 3y = 33
-2x - 10y = - 54 (result of multiplying by -2)
------------------add
-7y = - 21
y = -21/-7
y = 3
x + 5y = 27
x + 5(3) = 27
x + 15 = 27
x = 27 - 15
x = 12
so shorts (x) cost $12 and socks (y) cost $ 3 per pack
Answer:
Frank is correct.
Step-by-step explanation:
To convert 4.3 x
into regular notation I move the decimal 4 places to the right and get 43,000. This is way more than enough for the 5,000 yards needed for the carpet. So, Frank's wife is wrong about it not being enough.
