Using the equations y-3x=3 and x+y=31 you can find that x=7 and y=24. There for x is the smaller of the two numbers.

The correct answer is Choice B.

The first step in this problem is to divide both sides by 64.
On the left side, you will have b squared.
On the right side, you will have 1/4.

Now, take the square root of both sides.

The square root of 1/4 is positive or negative 1/2.

Which describes how the parent function, f(x) = |x|, is transformed to show the function f(x) = 0.1|x – 3|?

jarptica [38.1K]

Answer:

The answer is the option B

It is wider and shifted $3$ units to the right

Step-by-step explanation:

we have

$f\left(x\right)=\left|x\right|$

The vertex of the function is the point $(0,0)$

$f\left(x\right)=0.1\left|x-3\right|$

The vertex of the function is the point $(3,0)$

The function $f\left(x\right)=0.1\left|x-3\right|$ is wider than the function $f\left(x\right)=\left|x\right|$

Because it is multiplied by a number less than $1$

The rule of the translation is

$(0,0)-------> (3,0)$

$(x,y)-------> (x+3,y)$

That means

The translation is $3$ units to the right

see the attached figure to better understand the problem
