Answer:

$\left[\begin{array}{cc}-230&380\\-170&60\end{array}\right]$

Step-by-step explanation:

Notice that you are being asked to perform the product of a scalar (the number "-10" times a 2 by 2 matrix.

Such type of product requires the multiplication of each element of the matrix by the scalar "-10"

That means that the element 23 gets transformed into "-230"

The element -38 gets transformed into "380"

The element 17 gets transformed into "-170"

and lastly, the element -6 gets transformed into "60"

$\left[\begin{array}{cc}1-230&380\\-170&60\\end{array}\right]$ $\left[\begin{array}{cc}-230&380\\-170&60\end{array}\right]$

Such modification gets reflected in the second matrix listed among the possible answers.

Tannin and Dax bought a new video game for $48 to use the coupon for 25% off how much would the game cost if they paid full pric

olchik [2.2K]

Answer:

$64

Step-by-step explanation:

After using a 25% discount coupon, they paid 48 for the video game.

It means, which number, decreased by 25%, would give us 48?

First, 25% to decimal is:

25/100 = 0.25

Now, if we let the original price be "x", we can say:

x decreased by 0.25 of x would give us 48

Translating this to algebraic equation gives us:

x - 0.25x = 48

Now, we solve this:

$x - 0.25x = 48\\0.75x=48\\x=\frac{48}{0.75}\\x=64$

If they paid full price, the video game would cost $64

Which expression is equivalent to (7x+9y)2

Arada [10]

Answer:

$49x^2+126xy+81y^2$

Step-by-step explanation:

Use the square of a binomial theorem

$(a+b)^2$ = $a^2+2ab+b^2$

Now expand the given equation:

$(7x+9y)^2=49x^2+126xy+81y^2$

Hope this helps :)

Have a great day!

The product of any two numbers is composite ( true/false) and why?

Reptile [31]

FALSE.
A composite number is the opposite of a prime number. This is false because of the possibility of the following scenario:
The two numbers are 1 and a prime number.
This is because one multiplied by any number is that number. A prime number cannot become a composite number just because it is being multiplied by one. For example:
1 x 7 = 7 (prime)
Hope this helps!

Which inequality statement best represents the graph?

Akimi4 [234]

Answer:

Step-by-step explanation:

If you have choices, you really should list them.

Here is the graph for y = (x + 0.25)(x - 1.75) which will look like yours. There are all sorts of variations that are possible, but at least I could reproduce a similar looking graph.
