Start by completing the square.
x^2-8x-3y^2+12y=-16
x^2-8x+16-3(y^2-4y+4)=-16+16-12=-12
Notice the addition of those constants allows us to factor these expressions and because we did it to both sides it’s completely legit.
(x-4)^2-3(y-2)^2=-12
However, it seems we get a negative radius, which is not allowed. I think you entered the problem incorrectly.
Answer:
11.196%
Step-by-step explanation:
Given:
Buying cost of the investment or the principle amount = $1000
Time, n = 5 years
Selling cost of investment or amount received = $1700
Now,
the formula for compound interest is given as:

here, r is the rate of interest
on substituting the respective values, we get

or
(1 + r)⁵ = 1.7
or
1 + r = 1.11196
or
r = 0.11196
or
r = 0.11196 × 100% = 11.196%
Why did the person above me say ok for an answer
Step-by-step explanation:
slope/gradient
1 - (-4) / 4 - 0 = 5/4
y-intercept is -4 (this is the dot on y)
so the line equation is
y = 5/4x - 4 answer d
