Answer:

$\large\boxed{\left[\begin{array}{ccc}10&15&20\\45&-5&-35\\55&25&-15\end{array}\right] }$

Step-by-step explanation:

$n\times\left[\begin{array}{ccc}a&b&c\\d&e&f\\g&h&i\end{array}\right] =\left[\begin{array}{ccc}(n)(a)&(n)(b)&(n)(c)\\(n)(d)&(n)(e)&(n)(f)\\(n)(g)&(n)(h)&(n)(i)\end{array}\right] \\\\===============================$

$5\left[\begin{array}{ccc}2&3&4\\9&-1&-7\\11&5&-3\end{array}\right]\\\\=\left[\begin{array}{ccc}(5)(2)&(5)(3)&(5)(4)\\(5)(9)&(5)(-1)&(5)(-7)\\(5)(11)&(5)(5)&(5)(-3)\end{array}\right] \\\\=\left[\begin{array}{ccc}10&15&20\\45&-5&-35\\55&25&-15\end{array}\right]$

Help with 6 a and b please

34kurt

Answer:

a) $y=\frac{50}{x}$

b) $y=25$ when $x=2$

Step-by-step explanation:

$y=\frac{k}{x}$ since y varies inversely with x.

We need to find the constant, k.

Let's use a point (x,y) on the curve.

We are given an (x,y)=(5,10):

$10=\frac{k}{5}$

Multiply both sides by 5:

$10(5)=k$

$50=k$ .

So the equation is:

$y=\frac{50}{x}$

What is y when x=2?

$y=\frac{50}{2}$

$y=25$

Mags and Vector are playing a board game. They use a spinner to determine if they should move forward or backward. They roll a n

Aleksandr-060686 [28]

Answer:

1/4

Step-by-step explanation:

The sample space of an event is the list of all possible outcomes.

Let F represent moving forward and B represent moving backward. This makes the sample space for the game

F1, F2, F3, F4, F5, F6

B1, B2, B3, B4, B5, B6

There are 6 ways to move backward; only 3 of these are even numbers.

This is 3 ways out of 12 possible moves; this makes the probability

3/12 = 1/4

Graph y = x2 + 2. Identify the vertex of the graph. Tell whether it is a minimum or maximum. (0, 2); maximum (0, 2); minimum (2,

miskamm [114]

Answer:

$(0,2)$ ; minimum

Step-by-step explanation:

Given:

The function is, $y=x^{2}+2$

The given function represent a parabola and can be expressed in vertex form as:

$y=(x-0)^{2}+2$

The vertex form of a parabola is $y=(x-h)^{2}+k$ , where, $(h,k)$ is the vertex.

So, the vertex is $(0,2)$ .

In order to graph the given parabola, we find some points on it.

Let $x=-2,y=(-2)^{2}+2=4+2=6$

$x=-1,y=(-1)^{2}+2=1+2=3$

$x=0,y=(0)^{2}+2=0+2=2$

$x=2,y=(2)^{2}+2=4+2=6$

$x=1,y=(1)^{2}+2=1+2=3$

So, the points are $(-2,6),(-1,3),(0,2),(1,3),(2,6)$ .

Mark these points on the graph and join them using a smooth curve.

The graph is shown below.

From the graph, we conclude that at the vertex $(0,2)$ , it is minimum.
