What is the slope of the line on the graph?<br> WILL GIVE BRAINLIEST

inessss [21]

To find slope, you must find two points and use rise over run.
I'll use (0, -1) and (1, 5)
5 - (-1) $\frac{5-(-1)}{1-0}$ = 6
m= 6
So the slope is 6

Brainliest please!

Original price $69.80 with a 15% discount, what is the new price.

Mandarinka [93]

Answer:

$59.33

Step-by-step explanation:

To begin, let's start with what we know

Item = 69.80

Discount = 15% or 0.15

So, let's put it into this formula

New Price = Item ( 1 - Discount) Note: P is the final price

= 69.80 ( 1 - 0.15)

= 69.80 ( 0.85 )

= 59.33

The new price is $59.33.

Answer:

2. $\left[\begin{array}{ccc}1&4\\0&3\\\end{array}\right]$

3. $\left[\begin{array}{ccc}-3&21&60\\-15&9&-45\\\end{array}\right]$

4. $\left[\begin{array}{ccc}6&-14\\-2&-6\\\end{array}\right]$

Step-by-step explanation:

2. This matrix is easy, as it just requires addition.

$\left[\begin{array}{ccc}1&4\\0&3\\\end{array}\right]$ + $\left[\begin{array}{ccc}0&0\\0&0\\\end{array}\right]$ = $\left[\begin{array}{ccc}1&4\\0&3\\\end{array}\right]$

3. This matrix requires for the matrices to be multiplied first, then added.

$\left[\begin{array}{ccc}9&-15&18\\-27&15&-9\\\end{array}\right]$ + $\left[\begin{array}{ccc}-12&36&42 \\12& -6 & -36 \\\end{array}\right]$ = $\left[\begin{array}{ccc}-3&21&60\\-15&9&-45\\\end{array}\right]$

4. Here we can add the last 2 matrices to find x.

$\left[\begin{array}{ccc}2&-8\\-4&2\\\end{array}\right]$ + $\left[\begin{array}{ccc}4&-6\\2&-8 \\\end{array}\right]$ = $\left[\begin{array}{ccc}6&-14\\-2&-6\\\end{array}\right]$

Hope this helps! (Please consider giving brainliest)
