Answer:

not

Step-by-step explanation:

$\left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] *\left[\begin{array}{ccc}-2&1\\3&7\end{array}\right]=$

First is A and Second is B

Let's find A*B

$\left[\begin{array}{ccc}-2(-2)+4*3&-2*1+4*7\\1(-2)+3*3&1*1+3*7\end{array}\right] =\left[\begin{array}{ccc}16&26\\7&22\end{array}\right]$

$\left[\begin{array}{ccc}-2&1\\3&7\end{array}\right] \left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] =$

Now let's find B*A

$\left[\begin{array}{ccc}-2(-2)+1*1&-2*4+1*3\\3(-2)+7*1&3*4+7*3\end{array}\right] =\left[\begin{array}{ccc}5&-5\\1&23\end{array}\right]$

c) They are not

The polynomial p(x)=(3-2x)(x^2-5) is graphed in a coordinate plane. Which statement about the graph is correct?

satela [25.4K]

Answer:

0 = (3-2x) x (x x 2 -5)

(3-2x) x ( x x 2 - 5) = 0

(3-2x) x (2x - 5) = 0

3 - 2x = 0

2x - 5 = 0

x = 3/2

x = 5/2

x1 = 3/2 or x2 = 5/2
