La respuesta es 6.92 en su expresión más pequeña porque dice la altura de un triángulo equilátero es igual solo sacas las fórmula de la altura de un triángulo que es a^2=c^2+B^2 osea haci que sustituye con valores h^2= 8^2-4^2=h^2 8x8=64 4x4=16 64-16= √48 = 6.92

Answer:

See explanation

Step-by-step explanation:

Given the equation 3x-4y=12

A. Create the table of values for at least 4 points.

When x=0,

3\cdot 0-4y=12\\ \\-4y=12\\ \\y=-3

When x=2,

3\cdot 2-4y=12\\ \\-4y=12-6\\ \\-4y=6\\ \\y=-1.5

When x=4,

3\cdot 4-4y=12\\ \\-4y=12-12\\ \\-4y=0\\ \\y=0

When x=6,

3\cdot 6-4y=12\\ \\-4y=12-18\\ \\-4y=-6\\ \\y=1.5

When x=8,

3\cdot 8-4y=12\\ \\-4y=12-24\\ \\-4y=-12\\ \\y=3

Thus, the table is

\begin{array}{cc}x&y\\0&-3\\2&-1.5\\4&0\\6&1.5\\8&3\end{array}

B. Use the table of values to graph the line on the coordinate plane. Plot given points and connect them with the straight line (see attached diagram).

Please help me answer this I don't understand, I would really appreciate how you solved it as well.

Answer: Parallel

Step-by-step explanation:

Set your -2x+10y=5 equation equal to y

-2x+10y=5

<u>      -10y -10y</u>

-2x=5-10y

<u>-5      -5       </u>

<u>-2x-5</u>+<u>-10y</u>

-10 -10 -10

-1/5x-1/2=y

Now you can put your equations into your graphing calculator and examine the lines made

(if you dont have one search up <em>online graphing calculator</em> on google or your app store)

And animals weight change from 12 pounds to 16 pounds what was the percent increase to the nearest whole number
amm1812
That's a 33% increase.

I calculated this using the formula:

\frac{|n-o|}{o} * 100

Where n = the new value (16 in your question), o = the old value (12 in your question) and the result is outputted as a percent increase.  You can check that this is correct by finding 33% of 12, adding the result to 12, and checking that the result equals your "new" number.  

Note that 33% is only an approximation as your question requires a number rounded to the nearest whole.
