This table defines function f:

rodikova [14]

Answer:

Neither

Step-by-step explanation:

This function isn't even, because

$f(x) = f( - x)$

Basically this mean for every x opposites the y value should be the same.

Here, 6 and -6 doesn't share the same y value, nor as -3,and 3.

This function isn't odd because

$f( - x) = - f(x)$

Basically, this means our y values should be reflected about the orgin,

here, the y values does not switch signs for every x value and it's opposite itself , so this function isn't odd.

So The answer is neither

1. What is asked in the problem?

Scorpion4ik [409]

Answer:

See Explanation

Step-by-step explanation:

Given

See attachment

Solving (1): What is asked

The requirement of the question is to determine the difference between the amount of sugar used between yesterday and today

Solving (2): The given facts

$Yesterday = \frac{9}{10}kg$

$Today = \frac{3}{5}kg$

Solving (3): Operation to be used

We use subtraction operation

Solving (4): The mathematical sentence

$D = Yesterday - Today$

$D = \frac{9}{10}kg - \frac{3}{5}kg$

D represents the difference

Solving (5): The solution

$D = \frac{9}{10}kg - \frac{3}{5}kg$

Take LCM

$D = \frac{9 - 6}{10}kg$

$D = \frac{3}{10}kg$

4(x-b)=x solve for x please thanks

Allushta [10]

4(x−b)=xStep 1: Add -x to both sides.−4b+4x+−x=x+−x−4b+3x=0Step 2: Add 4b to both sides.−4b+3x+4b=0+4b3x=4bStep 3: Divide both sides by 3.3x/3=4b/3x=4/3bAnswer:x=4/3b

Need help with this ASAP! thank you!

Answer:

-4x^3 + 9x^2+35x -45

Step-by-step explanation:

The notation (f*g)(x) actually just means f(x)*g(x)

We just substitute what f(x) is and what g (x) is

(4x-9) * (-x^2 - 3x + 5 )

4x * -x^2 = -4x^3

4x * -3x = -12x

4x*5 = 20x

-4x^3 + -12x+20x

and

-9 * -x^2 = 9x^2

-9*-3x = 27x

-9*5 = -45

-4x^3 + -12x+20x + 9x^2 + 27x +-45

Now to put this in standard form, we have to order it with the terms with the highest exponents to the ones with the lowest exponents

-4x^3 + 9x^2 -12x+20x+27x -45

-12x+20x+27x

-12x+47x

35x

-4x^3 + 9x^2+35x -45

-45 goes last because it is equal to -45x^0

Using the following equation, find the center and radius of the circle. You must show all work and calculations to receive credi

adoni [48]

Answer:

$r = 4$

The center is:

(2, -4)

Step-by-step explanation:

We have the following equation

$x^2 - 4x + y^2 + 8y = -4$

The general equation of a circle has the following form

$(x-h)^2 + (y-k)^2 = r^2$

Where r is the radius and the point (h, k) is the center of the circle

To transform the given equation in the general equation of a circumference we must use the method of square completions

Step 1

$(x^2 - 4x) + (y^2 + 8y) = -4$

Step 2

Add and subtract $(\frac{b}{2})^2$ For an equation of the form

$ax^2 +bx +c$

$(x^2 - 4x +4)-4 + (y^2 + 8y +16) -16= -4$

Step 3 Factor the expressions within the parentheses

$(x-2)^2-4 + (y+4)^2 -16= -4$

Step 4 Simplify

$(x-2)^2 + (y+4)^2= -4+16+4$

$(x-2)^2 + (y+4)^2= 4^2$

Finally

$r = 4$

The center is:

(2, -4)
