Answer:

Step-by-step explanation:

Find the area of the rectangle, then add up the area of the triangle.

The area of the rectangle

= 5 × 12

= 60 cm²

The base of the triangle

= 12 - 9

= 3 cm

The height of the triangle

= 9 - 5

= 4 cm

The area of the triangle

= (3 × 4) ÷ 2

= 6 cm²

The total area of the figure

= 60 + 6

= 66 cm²

Which equation has a graph that is a parabola with a vertex at (–1, –1)?

Artist 52 [7]

Answer:

$y=(x+1)^2-1$

which agrees with the last option listed.

Step-by-step explanation:

We use the vertex form of a parabola:

$y-y_v=a(x-x_v)^2$

which with the information we have becomes:

$y-y_v=a(x-x_v)^2\\y-(-1)_v=a(x-(-1))^2\\y=a(x+1)^2-1$

Therefore the equation that corresponds to such vertex (-1, -1) is the last one listed among your given answer options.

$y=(x+1)^2-1$
