7x²+3y²-28x-12y=-19

grigory [225]

Complete the square for x and y.

7x^2 + 3y^2 - 28x - 12y = -19

7x^2 - 28x + 3y^2 - 12y = -19

7(x^2 - 4x) + 3(y^2 - 4y) = -19

7(x^2 - 4x + 4) + 3(y^2 - 4y + 4) = -19 + 28 + 12

7(x - 2)^2 + 3(y - 2)^2 = 21

$\dfrac{(x - 2)^2}{3} + \dfrac{(y - 2)^2}{7} = 1$

Does anyone know the answer? (It's not 0,4)

Murljashka [212]

I believe it would be any number that is within the darkest shaded area. (-4,1) seems like it would be correct.

Susan bought a bike for $93.75. If the bike was originally $125, what was the percent of discount?

Answer:

The discount is 25%

Step-by-step explanation:

Divide 93.75 by 125 = 75%

however, that is not the discount.

it is the difference of the 100 and the discount.

to find the discount, you do 100 - 75 = 25
