Answer:

(5+3y) (x+3)

first of all you bracket by (5x+15)(3xy+9y). and you start fact as follows by 5(x+3y) 3y(x+3)after here you take (5+3y) (x+3)

Answer:

(x+3)+(5+3y)

Step-by-step explanation: In the equation, when you have four terms you group like terms. So 5x+15 by itself and work it out which you will get 5(x+3) and do the same for 3xy+9y answer is 3y(x+3).

Then you will say 5(x+3)+3y(x+3) and then you'll

5(x+3)/(x+3)=5 because you will cancel the (x+3) so the answer would be 5

You will do the same for 3y(x+3)/(x+3)

you will get 3y

Finally, you will take the first equation which is (x+3), and then you'll use the last equation which is (5+3y)

So that's how you will get (x+3)+(5+3y)

What is the quotient of d − 2 √ d 4 − 5 d 3 + d + 17

Tcecarenko [31]

Answer: $d^3 - 3d^2-5$

Step-by-step explanation:

For finding the quotient of the given division,

In the long division method, we will follow the following steps.

Step 1 : Here the divisor is d-2 and dividend is $d^4-5 d^3 + d + 17$

Multiply (d-2) by $d^3$ and subtract the dividend by the resultant.

We get $-3d^3+d$

Step 2: Multiply (d-2) by $-3d^2$ and subtract the remaining dividend by the resultant.

We get $-5d^2+17$

Step 3 : Multiply (d-2) by $-5$ and subtract the remaining dividend by the resultant.

We get $7$

Since, after getting 7 it is not possible further division,

Hence, Remainder = 7,

Quotient = sum of all expression by that we multiply (d-2) = $d^3 - 3d^2-5$

How do you do this question?

Mekhanik [1.2K]

Answer:

(-∞, -2), (-2, -0.618), and (1.618, 3)

Step-by-step explanation:

The red arrows indicate the regions in which the function is decreasing.

The corresponding intervals are (-∞, -0.618) and (1.618, 3),

Let's examine the intervals given.

(-∞, -2): Yes, decreasing.

(-2, -0.618): Yes, decreasing.

(-2, 0.689): No. Decreasing in (-2, -0.618) but increasing in (-0.618, 0.689).

(-1.17, 0.689): No. Decreasing in (-1.17, -0.618) but increasing

in (-0.618, 0.689).

(0.698, 71.457): No. Increasing from (0.698, 1.618), decreasing in (1.618, 3) and increasing in (3, 71.457).

(1.618, 3): Yes, decreasing.

(2.481, ∞): No. Decreasing in (2.481, 3) but increasing in (3, ∞).

The three choices that indicate a decreasing interval are (-∞, -2),

(-2, -0.618), and (1.618, 3).

What is the average rate of change for <br><br> f (x)=0.5 (-10x + 24)?

xenn [34]

Answer:

The rate of change of the function is -5.

Step-by-step explanation:

Given : Function $f(x)=0.5(-10x+24)$

To find : What is the average rate of change ?

Solution :

Function $f(x)=0.5(-10x+24)$

The rate of change is the first derivative.

$f(x)=-5x+12$

Derivate w.r.t. x,

$f(x)=-5$

Therefore, The rate of change of the function is -5.
