Answer:

Slope = -8/5

Step-by-step explanation:

Use the slope formula:

m = y2 - y1 / x2 - x1

Plug in the numbers from the ordered pairs given in the graph: (-1, 4) and (4, -4).

m = -4 - 4 / 4 - - 1

m = -8 / 5

m = -8/5

m = rise/run, meaning verticl units/horizontal units

Check your work by counting it out on the graph:

From the first black dot at (-1, 4), count 8 units down and then 5 units to the right. After counting, I ended at the second ordered pair at (4, -4) which means my slope is correct.

Principle=$745 rate= 9% time= 4years

Dennis_Churaev [7]

Based on a yearly rate (which is the norm) I give you my answer ..

Your principle is at 745$
Annual Rate 9%

For the first year your principle will grow by 67.05 $ if untouched (9%) up to 812.05 $

2nd year .. 9% of the 812.05 $ is 73.0845 $ .. So by the 2nd year you reach 885.1345 $

3rd year .. 79.662105 $ .. Total 964.796605 $

4th year .. 86.83169445 $ .. <u>Final</u><u> 4 Years </u><u>Total 1051.62829945 $</u>

Shawna, Dexter, and Tilana are solving the equation Negative 2. 5 (5 minus n) 2 = 15. Shawna says, "I can begin by dividing each

aleksandrvk [35]

Shawana, Dexter, and Tilana are correct.

<h2>Given that</h2>

Equation: $\rm -2.5(5 - n) + 2 = 15


$

<h3>We have to determine</h3>

Which students are correct?

<h3>According to the question</h3><h3>Equation: $\rm -2.5(5 - n) + 2 = 15


$ </h3>

The correct way to solve the equation is;

SHAWNA

Statement: Dividing each side of the equation by –2.5,

$\rm \dfrac{-2.5(5 - n) + 2 }{-2.5}= \dfrac{15}{-2.5}\\
\\
(5-n) - \dfrac{2}{2.5} = \dfrac{15}{-2.5}\\\\
\\
$

Here, Shawna is correct.

DEXTER

Statement: Distributing -2.5 to get -12.5 + 2.5 n + 2 = 15.

$\rm -2.5(5-n) +2=15\\
\\
-2.5(5) - 2.5 (-n) +2= 15\\
\\
-12.5 +2.5n +2=15$

Hence, Dexter is correct.

" Tirana says, "I can begin by multiplying each side of the equation by Negative Start fraction 1 over 2. 5 End fraction to get 5 minus n minus 0. 8 = negative 6. "

$\rm \dfrac{-1}{2.5} (-2.5 (5-n)+2)= \dfrac{-1}{2.5}\times 15\\
\\
(5-n) + \dfrac{-2}{2.5} = \dfrac{-15}{2.25}\\
\\
(5-n) -\dfrac{2}{2.5} = \dfrac{-15}{2.5}\\
\\
5-n-0.8=-6$

Hence, Tilana is also correct.

Hence, Shawana, Dexter and Tilana are correct.
