PLS HELP. Find the first four terms of the recursive sequence defined by the following formula:

Gnoma [55]

Answer:

see explanation

Step-by-step explanation:

Given the recursive formula $a_{n}$ = $\frac{a_{n-1} }{4}$ and

$a_{4}$ = 2 $\frac{1}{4}$ = $\frac{9}{4}$ , then

$\frac{a_{3} }{4}$ = $\frac{9}{4}$ ( multiply both sides by 4 )

a₃ = 4 × $\frac{9}{4}$ = 9

$\frac{a_{2} }{4}$ = 9 ( multiply both sides by 4 )

a₂ = 36

$\frac{a_{1} }{4}$ = 36 ( multiply both sides by 4 )

a₁ = 144

The first 4 terms are

144, 36, 9, 2 $\frac{1}{4}$

Find the slope and y-intercepts <br> f(x)= -1/2x - 2

gavmur [86]

Answer:

slope: -1/2

y-intercept: -2

Step-by-step explanation:

f(x) = mx+b

m is slope

b is the y-intercept

if f(x) = -1/2x - 2

then

the slope or m is -1/2

and the y-intercept or b is -2

If f(X+4) =3x+4 , then find the value of f(4) <br>please explain it clearly .

Paul [167]

$\\ \sf\longmapsto f(x+4)=3x+4$

$\\ \sf\longmapsto f(x)=3x+4-4$

$\\ \sf\longmapsto f(x)=3x$

Now

$\\ \sf\longmapsto f(4)$

$\\ \sf\longmapsto 3(4)$

$\\ \sf\longmapsto 12$
