Point S is on line segment \overline{RT}

Semenov [28]

Answer:

RT = 20

Step-by-step explanation:

Point S is on line segment

R------------S------------T

RS + ST = RT

Given

ST=3x-8

RT=4x

RS=4x-7,

Step 1

We find x

4x - 7 + 3x - 8 = 4x

4x + 3x -7 - 8 = 4x

7x - 15 = 4x

7x - 4x = 15

3x = 15

x = 15/3

x = 5

Step 2

We find RT

RT = 4x

x = 5

RT = 4 × 5

RT = 20

The numerical length of RT is 20

What is the explicit formula for this geometric sequence with recursive formula

Nonamiya [84]

generate the first few terms using the recursive formula

$a_{2}$ = - 7 × $\frac{1}{3}$ = - $\frac{7}{3}$

$a_{3}$ = - $\frac{7}{3}$ × $\frac{1}{3}$ = - $\frac{7}{9}$

$a_{4}$ = - $\frac{7}{9}$ × $\frac{1}{3}$ = - $\frac{7}{27}$

r = $a_{2}$ / $a_{1}$ = $\frac{1}{3}$

the n th term formula (explicit ) for a geometric sequence is

$a_{n}$ = $a_{1}$ $r^{n-1}$ = - 7( $\frac{1}{3}$ )^(n - 1)

Complete the solution of the equation. Find the value of y when x equals -2. -4x+8y=-24

zepelin [54]

Answer:y=-4

Step-by-step explanation:

Multiply -4 by -2 you get positive 8 rewrite the equation subtract 8 from both sides that leaves you with 8y=-32 your final step is to divide both sides 8 that leaves you with -4 which is the answer.
