One of the property of rectangle is opposite sides are equal
Therefore 9x+12=4x+47

9x+12=4x+47
5x=35
Therefore x=7

Step-by-step explanation:

A) opposite sides in a rectangle is always equal

B) 9x+12 = 4x +47

Transpose = 9x - 4x = 47 - 12

solve = 5x = 35

Divide both sides by 5

x = 7

If standard form is x-2y=6 <br> how do you get the ordered pairs?

o-na [289]

Actually the line would be y=x/2 -3, this is in y=mx+b form. And normally they give you the ordered pairs.

Write the composite function in the form f(g(x)). [Identify the inner function u = g(x) and the outer function y = f(u).] $ y =

Advocard [28]

Answer:

The answer is " $\frac{5 e^{5\sqrt{x} }}{2\sqrt{x}}$ ".

Step-by-step explanation:

Given:

$y = e^{{\color{\red}5}\sqrt{x}}$

let

$\to t= 5\sqrt{x}\\\\\frac{dt}{dx}= 5 \frac{1}{2\sqrt{x}}\\\\\frac{dt}{dx}= \frac{5}{2\sqrt{x}}\\\\$

and

$\to y=e^t\\\\\to \frac{dy}{dt}=e^t\\$

$\to \frac{dy}{dt}=e^{5\sqrt{x} }\\$

So,

$\to \frac{dy}{dx}= \frac{dy}{dt} \times \frac{dt}{dx}$

$=e^{5\sqrt{x} }\times \frac{5}{2\sqrt{x}}\\\\= \frac{5 e^{5\sqrt{x} }}{2\sqrt{x}}$

$\to g(x) = 5\sqrt{x} \\\\\to f(x) = e^{(x)}\\\\$

Derivate:

$\to f''g' = \frac{e^{(5\sqrt{x})}5}{(2\sqrt{x})}$

In logic, a condition that must be satisfied for a statement to be true, but does not in and of itself make it true. Sufficient

Archy [21]

Answer:

Correlation

Step-by-step explanation:

This can be explained if we consider the case of correlation as in correlation this condition can arrive where a statement should be satisfied to be true when does not in or make it true itself.

Correlation is indicative of the degree to which there is a fluctuation in one more varying values together. The increase or decrease in the value is indicated by the positivity or negativity of the correlation respectively where the correlation itself does not make it true or is true in itself.
sufficient and necessary conditions are fulfilled only when one value needs to be true or false for the other to be true or false respectively.

Causality also known as causation is the effectiveness or potency in which one process or a cause, leads to the generation of of another process or an effect, where cause and effect are partially dependent on each other.
