F(x) = | 3x+1 | find the vertex of value function

PilotLPTM [1.2K]

Answer:

The vertex is the point $(-\frac{1}{3},0)$

Step-by-step explanation:

we know that

The general form of an absolute value equation is

$y=a\left|x-h\right|+k$

The variable a tells us how far the graph stretches vertically, and whether the graph opens up or down. The variables h, and k, tell us how far the graph shifts horizontally and vertically

The vertex is the point (h,k)

we have

$f(x)=\left|3x+1\right|$

Rewrite the expression (3x+1)

$(3x+1)=\frac{3}{3} (3x+1)=3(x+\frac{1}{3})$

substitute

$f(x)=\left|3(x+\frac{1}{3})\right|$

$f(x)=3\left|(x+\frac{1}{3})\right|$

$a=3\\h=-\frac{1}{3}\\k=0$

therefore

The vertex is the point $(-\frac{1}{3},0)$

see the attached figure to better understand the problem

The ratio of the width of a rectangle to it's length is 3:4. The length of the rectangle is 36 cm. Find the rectangles width.

Fiesta28 [93]

Answer:

27 cm

Step-by-step explanation:

So the ratio you have is

width(x) : length (36)= 3:4

Divide 36 (length) by the ratio length. 36÷4=9

They are multiples of nine, so multiply the width by 9 to get the 3.

3×9=27

You have 27:36

If you want to check it, divide both by 9 and you get 3:4
