<span>A=(-2+4/5)² qual valor de A?

</span>A=\left(-2+ \dfrac{4}{5}\right)^2 \\  \\  \\ A=\left( \dfrac{-2*5+4}{5}\right)^2 \\  \\  \\ A=\left( \dfrac{-10+4}{5}\right)^2 \\  \\  \\ A=\left( \dfrac{-6}{5}\right)^2 \\  \\  \\ A=\left( \dfrac{(-6)^2}{(5)^2}\right) \\  \\  \\ \boxed{  A= \dfrac{36}{25} } \\  \\  \\<span>

So, it went down from 28 to 7, meaning 28 - 7 = 21, 21 feet then.

now, if we take 28 to be the 100%, what is 21 off of it in percentage?

\bf \begin{array}{ccll}&#10;amount&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;28&100\\&#10;21&p&#10;\end{array}\implies \cfrac{28}{21}=\cfrac{100}{p}\implies p=\cfrac{21\cdot 100}{28}

What is the slope of the line that passes through the points (1, 3) and (5, –2)?
Sergeu [11.5K]

m=-(5/4)

From left to right, (1,3) is first and then comes (5,-2). Always remember when finding slopes without equations, the rule is RISE over RUN, to the numerator and denominator, respectively.

The y value of the second coordinates becomes negative which is unlike the y value in the first coordinates, which means our slope is downward, meaning it has a negative sign in front.

In every slope, there’s a numerator, being the rise, and a denominator, being the run.

To find the rise, we must look at the y values. Starting at 3 going to -2 has a space of 5 units, making that our numerator.

To find the run, the first x value is 1 and the second is 5, making a space of 4, which is out denominator.

With these two numbers and the negative sign, we get -(5/4) as our slope.

First, find the ratio between the two polygons. Lets take segment MG and TV since they are congruent. MG is 4, TV is 3. The ratio of MG to TV is 4:3. We can write it as 4/3. Since other arts are congruent as well, then NK is congruent to PR, and has a ratio of 4:3. This means that (3x-2)/(x+4) is equal to 4/3. Now solve for x
(3x-2)/(x+4)=4/3 
3(3x-2)=4(x+4)         ---cross multiply
9x-6=4x+16
9x-4x-6=4x-4x+16    ---subtract 4x from both sides
5x-6=16
5x-6+6=16+6            ---add 6 on both sides
5x=22
5x/5=22/5                 ---divide 5 on both sides
x=22/5
