PLEASE HURRY!!!!! What is the turning point of the graph of f(x) = |x – 4| ?

1 answer:

8 0

$f(x)=|x-4|\\
f'(x)=\text{sgn} (x-4)\\
\text{sgn} (x-4)=0\\
x-4=0\\
x=4\\\\

$

For $x$ $f'(x)$ .
For $x>4$ $f'(x)>0$ .
$\Downarrow\\
$
At $x=4$ there's turning point, which is equal $|4-4|=|0|=0$ .

Find the value of x when : 2^30/8^9=2^x

artcher [175]

Answer:

x = -3

Step-by-step explanation:

Okay, the first thing to do is get that 8 away from the fraction. How can we do it? When you have 2³ you have 8, is the same thing, so let's do it:

2³⁰/(2³)⁹ = 2^x

When you have a number with the shape (a^x)^y, you can write it as a^(x•y), so:

(2³)⁹ = 2^3•9 = 2²⁷

Now we have:

2³⁰/2²⁷ = 2^x

When you have a division like this: (a^x)/(a^y), you can write it as a^(x-y), so:

2^(30-27) = 2^x

2^-3 = 2^x

Now you know that x = -3

48 divided by four fifths

Fed [463]

Answer:

The answer is 60.

Step-by-step explanation:

$\frac{48}{1}$ ÷ $\frac{4}{5}$

Now, apply the fraction rule(\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}):

$\frac{48}{1}$ × $\frac{5}{4}$

Cross-cancel(common factor of 4):

$\frac{12}{1}$ × $\frac{5}{1}$

Multiply:

$\frac{12 x 5}{1 x 1}$

Simplify:

12 x 5=60

The answer is 60

hope this helps :)

Which graft represent -3x+5y=-15

azamat

The graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

-3x + 5y = -15

The above function shows a linear function we can write it as:

5y = 3x - 15

y = (3x - 15)/5

If x = 0, y = -3

x = 1, y = -2.4

x = 2, y = -1.8

x = -1, y = -3.6

x = -2, y = -4.2

Thus, the graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.

Please help. I will give 16 points.

Allushta [10]

Answer:

(4, -2)

Step-by-step explanation:

if you do process of elimination you find that 'a' doesn't work out but 'b' will . . . substitute -2 for 'y' and 4 for 'x' and see if the equation is true

-2 = -3/4(4) + 1

-2 = -3 + 1

-2 = -2
