The vertex of the parabola below is at the point (5,-3). Which of the equations
below could be the one for this parabola?

A. X = 3(y + 3)2 + 5
B. x = 3(y - 5)2 - 3
C. X= -3(y + 3)2 + 5
D. y = -3(x - 5)2-3

The vertex of a parabola is written as (h,k) so h = 5 and k = -3.

H is subtracted from x inside parentheses and k is added at the end of the equation.

The equation is also written as y =

The answer should be D.

Answer c also works, so there are two correct answers.

answer: h

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
