Answer:

d= 2

Step-by-step explanation:

To find the common difference, take the second term and subtract the first

-2 - (-4)

-2+4 = 2

We add 2 each time

Lets check

Take the third term and subtract the second

0- -2

0+2 =2

The common difference is 2

What is the best estimate of the sum of the fraction? 31/4 +17/3 +8/18

Bogdan [553]

The best estimate of the sum of the expression given is $\rm 13 \dfrac {31}{26}$

What is a Fraction ?

A fraction is written as p/q , where q $\rm \ne$ 0

It is asked to determine the sum of the fraction

31/4 + 17/3 + 8/18

Taking the LCM of 4 , 3 , 18

LCM of 4 , 3 ,18 is 36

Therefore

$\rm \dfrac{ 31 *9 + 17 *12 + 8 *2}{36 }$

(279+204+16) /36

499 / 36

$\rm 13 \dfrac {31}{26}$

Therefore the best estimate of the sum of the expression given is $\rm 13 \dfrac {31}{26}$ .

<h3>Answer:</h3>

$f(x) = 0 \text{ when } x = \bold{1}$

$f(-7) =\bold{224}$

<h3>Step-by-step explanation:</h3>

Solving for the input, $\bold{x}$ , given the output:

Given:

$f(x) = 4x -4$

Solving for $x$ from the equation, $f(x) = 0$ :

$f(x) = 0 \\ 4x -4 = 0 \\ 4x = 4 \\ x = \frac{4}{4} \\ x = 1$

Solving for the output, $\bold{f(x)}$ , given the input.

Given:

$f(x) = 4x^2 -4x$

Solving $f(-7)$ :

$f(-7) = 4(-7)^2 -4(-7) \\ f(-7) = 4(49) -4(-7) \\ f(-7) = 196 +28 \\ f(-7) = 224$
