a sequence is defined by ths formula (n+1)=f(n)+3 the first term of the sequence is -4 what is the next term in the sequence

jenyasd209 [6]

How I understand from your writing next term is equal previous plus 3,
if 1st is -4, then next (second) should be -4+3= -1

Answer:

The factors of $2(x+y)^2-9(x+y)-5$ is ((x+y)-5)(2x+2y+1)

Step-by-step explanation:

Given polynomial

=> $2(x+y)^2-9(x+y)-5$

To Find:

The factors of the polynomial =?

Solution:

Lets assume k = (x+y)

Then $2(x+y)^2-9(x+y)-5$ can be written as $2k^2-9k-5$

Now by using quadratic formula

k = $\frac{-b\pm\sqrt{(b^2-4ac}}{2a}$

where

a= 2

b= -9

c= -5

Substituting the values, we get

k = $\frac{-b\pm\sqrt{(b^2-4ac)}}{2a}$

k = $\frac{-(-9) \pm \sqrt{((-9)^2-4(2)(-5)}}{2(2))}$

k = $\frac{-(-9) \pm \sqrt{(81+40)}}{4}$

k = $\frac{-(-9) \pm \sqrt{(121)}}{4}$

k = $\frac{-(-9) \pm 11}}{4}$

k= $\frac{ 9 \pm 11}{4}$

k = $\frac{20}{4}$ k = $\frac{-2}{4}$

$k_1 =5$ $k_2 = -\frac{1}{2}$

$2k^2-9k-5= 2(k-5)(k+\frac{1}{2})$

Solving the RHS we get

$\frac{2}{2}(k-5)(2k+1)$

$(k-5)(2k+1)$

Substituting k = x+y

$((x+y)-5)(2(x+y+1)$

$((x+y)-5)(2x+2y+1)$

Find the slope please

zavuch27 [327]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find the slope of this graph; we are provided with two points:

$\star~\mathrm{(6,0)}$

$\star~\mathrm{(0,-5)}$

$\triangle~\fbox{\bf{KEY:}}$

What we need in order to find the slope are two points and the slope formula.

Here's the formula:

$\star~\boxed{\mathrm{\cfrac{y2-y1}{x2-x1}}}$

Where

y2 and y1 are y-coordinates

x2 and x1 are x-coordinates

Substitute the values:

$\star~\mathrm{\cfrac{-5-0}{0-6}}}$

Simplify!

$\star~\mathrm{\cfrac{-5}{-6}}}$

Simplify more!

$\star~\mathrm{\cfrac{5}{6}}$

Hope it helps you out! :D

Ask in comments if any queries arise.
