Answer:
Coordinate D. Because D lies on the 2nd quadrant, meaning that x has a negative value whereas y is positive.
20% off means you are paying 80% of the original price ( 100% - 20% = 80%)
Multiply the price of the tv by 80% to find the sale price:
500 x 0.80 = 400
Now multiply the sales price by 1 plus the tax rate to find final cost:
400 x 1.06 = 424
Final price including tax is $424
Step-by-step explanation:
2x²+2xy+yx+y²+2x²+2xy-yx+y²
2x²+2x²+2xy+2xy+yx-yx+y²+y²
2x²+2x²+2xy+2xy
4x²+4xy
25.75% say no- 206/80 then * 10 (x)
74.25% say yes- 100-x
Y=1/x solve for x
x=1/y now reverse lables...
y=1/x
Yes that is the same equation you started with. What that means is the the inverse function in this case produces the same exact graph :)
