♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

∆ABC and ∆ADE are similar triangles.

Thus ;

\frac{AD}{AC}  =  \frac{DE}{BC}  =  \frac{AE}{AB}  \\

So :

\frac{5}{3 + 2x}  =  \frac{4}{8}  \\

\frac{5}{3 + 2x}  =  \frac{1}{2}  \\

Inverse both sides

\frac{3 + 2x}{5}  =  \frac{2}{1}  \\

\frac{2x + 3}{5}  = 2 \\

Multiply sides by 5

5 \times  \frac{2x + 3}{5}  = 5 \times 2 \\

2x + 3 = 10

Thus ;

AC = 2x + 3 = 10

AC = 10

Done...

Given that (-3,7) is on the graph of f(x), find the corresponding point for the function f(x + 5).
natulia [17]

Given transformation is f(x+5) which is similar to f(x+h).

f(x+h) shifts the graph "h" units to the left side.

so that means f(x+5) will shift the graph "5" units to the left side.

Left or right movement is done using x-coordinate only so -3 will change in (-3,7)

-3+5=2

so the new coordinate of the point will be (2,7)

Hence final answer is (2,7).

Given that (-5,-6) is on the graph of f(x), find the corresponding point for this function -1/3f(x).
masya89 [10]
<h3>Answer:  (-5, 2)</h3>

Explanation:

We multiply the y coordinate by -1/3 because of the notation (-1/3)*f(x). Recall that y = f(x). The x coordinate stays the same.

Can someone explain how to convert a quadratic function in standard form to vertex form using the "complete the square" method?
Arisa [49]

The required steps are explained below to convert the quadratic function into a perfect square.

<h3>What is the parabola?</h3>

It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.

Let the quadratic function be y = ax² + bx + c.

The first step is to take common the coefficient of x². We have

\rm y = a \left (x^2 + \dfrac{b}{a}x \right) + c

Add and subtract the half of the square the coefficient of x,

\rm y = a \left (x^2 + \dfrac{b}{a}x + \dfrac{b^2}{4a^2} \right) - a \times \dfrac{b^2}{4a^2} + c

Then we have

\rm y = a \left (x + \dfrac{b}{a} \right)^2 - \dfrac{b^2}{4a} + c

These are the required step to get the perfect square of the quadratic function.

More about the parabola link is given below.
