the first three terms of an arithmetic progression is (x + 1), (4 x - 2) and 6 x - 3 if the last term is 18 find the value of x

lbvjy [14]

Answer:

2

Step-by-step explanation:

<u>Since it is AP, the common difference is same for any term:</u>

(4x - 2) - (x + 1) = (6x - 3) - (4x - 2)
3x - 3 = 2x -1
3x - 2x = 3 - 1
x= 2

<u>The first 3 terms are:</u>

3, 6, 9

<u>Since the last term is 18, it means this AP has 6 terms:</u>

{3, 6, 9, 12, 15, 18}

<u>Answer: </u>as we need to find the value of x only, it is = 2

velikii [3]

If you divide 16 by 2 you get 8, so, 8 teams payed $50, while the other half payed $60.

Hope this helps. ^_^

(If you're gonna add them up it's 8x60=480 + 8x50=400=880) :P

Precalculus question, image attached.

Answer:

g(x)= x+1

Step-by-step explanation:

$h(x)= (fog)(x)= f(g(x))$

Given $f(x)= \sqrt[3]{x+2}$ , $f(x)= \sqrt[3]{x+3}$

$f(g(x))= \sqrt[3]{x+3}$

$f(x)= \sqrt[3]{x+2}$

Replace x with g(x)

$f(g(x))= \sqrt[3]{g(x)+2}$

Now we need to find out what we plug in for g(X) to get x+3 under the radical

g(x) +2 is under the radical. we need x+3 , so we replace g(x) with x+`

So g(x)+2 becomes x+1+2 is x+3

Hence g(x) is x+1
