The first one
Y=-3x+2
First you get the slope by Y-Y/X-X
Of any 2 points
Then get the equation by substituting one of the coordinates

Hi can anyone help me with my math? thanks x

Katen [24]

It's multily
f(x) time g(x) is basically what they wnat

so

(x^2+8x+15) times (5/(x^2-9))
hold a sec, first factor each
(x+3)(x+5) times 5/((x-3)(x+3))
we get
((x+3)(x+5)(5))/((x-3)(x+3))
(x+30 cancels out
((x+5)(5))/(x-3)
(5x+25)/(x-3)

Sauron [17]

Answer:

The $n^{th}$ sequence aₙ = -15 +5n

The fifth term of the sequence

a₅ = 10

Step-by-step explanation:

Step(i):-

Given sequence

-10,-5,0,5,10,15,20,.....

The first term = -10

The difference of two terms in the given sequence is equal

d = -5-(-10) = -5 + 10 = 5

d = 0 -(-5) = 5

The given sequence is in arithmetic progression

Step(ii):-

The $n^{th}$ sequence

$a_{n} = a+(n-1) d$

aₙ = -10 +(n-1) 5

aₙ = -10 + 5n -5

aₙ = -15 +5n

Step(iii):-

The $n^{th}$ sequence aₙ = -15 +5n

put n = 5

a₅ = -15 + 5(5) = -15 +25 = 10

Final answer:-

The $n^{th}$ sequence aₙ = -15 +5n

The fifth term of the sequence

a₅ = 10
