Answer:

Step-by-step explanation:

The rule gives the sequence ...

75, 69, 63, 57, 51, 45, ...

The 5th number in the sequence is 51.

Alternate solution

The equation for the general term of an arithmetic sequence is ...

an = a1 +d(n -1) . . . . . for first term a1 and common difference d

Your sequence has first term 75 and common difference -6, so the equation is ...

an = 75 -6(n -1)

Then for n=5, the term is ...

a5 = 75 -6(5 -4) = 75 -24 = 51

The 5th term is 51.

someone pls help meeeee!!!!!!

GuDViN [60]

Step-by-step explanation:

y = y

x - 2 = 2x - 3 - 3x²

3x² + x - 2x = - 3 + 2

3x² - x = - 1

a = 3, b = -1, c = 0

$\sf{x = \frac{-b \pm \sqrt{b^{2} - 4ac} }{2a} }$

$\sf{x = \frac{- (-1) \pm \sqrt{-1^{2} - 4 (0)} }{2(3)} }$

$\sf{x = \frac{ 1 \pm \sqrt{1 - 0} }{6} }$

$\sf{x = \frac{ 1 \pm \sqrt{1} }{6} }$

$\sf{x = \frac{ 1 + 1 }{6} }$

$\sf{x = \frac{ 2 }{6} }$

$\sf{x = \frac{ 1 }{3} }$

Substitution :

y = x - 2

y = ⅓ - 2

y = ⅓ - 6/3

y = - 5/3

y = - 1 ⅔
