The vertex of the graph is at (-2, 3).

This means the equation is of the form $f(x)=a|x+2|+3$ .

Substituting in the coordinates of one of the other points on the graph that is not the vertex, such as (-1, -1),

$-1=a|-1+2|+3\\\\-1=a+3\\\\a=-4$

So, the equation is $\boxed{f(x)=-4|x+2|+3}$

PLZ HELP ME PLZ I don't understand this

Answer:

Step-by-step explanation:

For this equation we have to plug in, so z= 6 and w=7. the question is 8z+7w

so plug in 6 for z and 7 for w. 8(6)+7(7) so 8*6 is 48 and 7*7= 49. 48+49= 97

hope this helps :)

ANSWER

EXPLANATION

For a matrix A of order n×n, the cofactor $C_{ij}$ of element $a_{ij}$ is defined to be

$C_{ij} = (-1)^{i+j} M_{ij}$

$M_{ij}$ is the minor of element $a_{ij}$ equal to the determinant of the matrix we get by taking matrix A and deleting row i and column j.

Here, we have

$C_{11} = (-1)^{1+1} M_{11} = M_{11}$

M₁₁ is the determinant of the matrix that is matrix A with row 1 and column 1 removed. The bold entries are the row and the column we delete.

$\begin{aligned} A=\begin{bmatrix} \bf 1 & \bf -6 & \bf -4\\ \bf 7 & 0 & -3 \\ \bf -9 & 8 & -8 \end{bmatrix} \implies M_{11} &= \text{det}\left(\begin{bmatrix} 0&-3 \\ 8&-8 \end{bmatrix} \right) \end{aligned}$

Since the determinant of a 2×2 matrix is

$\det\left( \begin{bmatrix} a & b \\ c& d \end{bmatrix} \right) = ad-bc$

it follows that

so $C_{11} = M_{11} = 24$
