Answer:

y = -(x + 1)² + 4

Step-by-step explanation:

y = -x² − 2x + 3

First, factor the leading coefficient from the first two terms.

y = -(x² + 2x) + 3

Complete the square.

y = -(x² + 2x + 1 − 1) + 3

Simplify and factor.

y = -(x² + 2x + 1) + 1 + 3

y = -(x + 1)² + 4

tatiyna

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$4x+4y=16$ -----> equation A

$x+6y=-6$ -----> equation B

we know that

The solution of the system of equations is the intersection point both graphs

In this problem

The intersection point is $(6,-2)$

therefore

The solution is the point $(6,-2)$

using a graphing tool

ahrayia [7]

Answer:

k < - 1

Step-by-step explanation:

28 + 3k < 5(-3-8k)

28 + 3k < - 15 - 40k

28 + 15 < - 40k - 3k

43 < - 43k

43/- 43 > k (switch signs because 43 is negative)

k < -1
