7/8 / 11/12. First get the reciprocal of 11/12 (which is 12/11). Then multiply by the reciprocal. 7/8 * 12/11 = 84/88 don't forget to simplify 21/22

7/8 time the reciprocal of 11/12 would be 12/11
7/8 times 12/11
7 times 12 is 84 and 11 times 8 is 88
so ur fraction is 84/88
simplify 21/22

Given the explicit expression f (n) = 5n - 2, write a set showing the sequence, and write a recursive expression.

denpristay [2]

Answer:

$f(n) = 5 + f(n - 1)$

Step-by-step explanation:

Given

$f(n) = 5n - 2$

Required

Write a recursive expression

$f(n) = 5n - 2$

When n = 1

$f(1) = 5 * 1 - 2 = 5 - 2 = 3$

$f(1) = 3$

When n = 2

$f(2) = 5 * 2 - 2 = 10 - 2 = 8$

$f(2) = 8$ can be rewritten as

$f(2) = 5 + 3$

Substitute 3 for f(1)

$f(2) = 5 + f(1)$

Express 1 as 2 - 1

$f(2) = 5 + f(2-1)$ ----- (1)

When n = 3

$f(3) = 5 * 3 - 2 = 15 - 2 = 13$

$f(3) = 13$ can be rewritten as

$f(3) = 5 + 8$

Substitute 8 for f(2)

$f(3) = 5 + f(2)$

Express 2 as 3 - 1

$f(3) = 5 + f(3 - 1)$ ------ (2)

Write out (1) and (2)

$f(2) = 5 + f(2-1)$

$f(3) = 5 + f(3 - 1)$

Replace 2 and 3 with n in both cases; This gives

$f(n) = 5 + f(n - 1)$

Hence;

The recursive is $f(n) = 5 + f(n - 1)$

Answer:

1. X= 56

2. X= -11/2 (When you solve you get this if you need it as a mixed number it's X= -5 1/2

Step-by-step explanation:

simplifying means: Reducing to lowest terms.

To solve for x simplify both sides of the equation, then isolate the variable.

What is the slope of the line that passes (-11,2) and (-1, -13). Plz show your work.

ANEK [815]

Answer:

Slope = -3/2 or -1.5

Step-by-step explanation:

The Formula for slope is (The picture linked)

So, $\frac{-13-2}{-1-(-11)}$

Which is equal to... $\frac{-15}{10}$ when simplified

Which is equal to $\frac{-3}{2}$ or -1.5 which is the slope
