Answer:

$\boxed{\dfrac{y}{x}}$

Step-by-step explanation:

$\dfrac{\dfrac{1}{x} }{\dfrac{1}{y} } \ \text{can also be written as} \ \dfrac{1}{x} \div \dfrac{1}{y}$

-------------------------------------------

$\rightarrow \dfrac{1}{x} \div \dfrac{1}{y}$

<u>Simplifying the expression using "a ÷ b = a x 1/b"</u>

$\rightarrow \dfrac{1}{x} \times y$

$\rightarrow \boxed{\dfrac{y}{x}}$

Jillian is looking up certain cities' elevations. She finds that New Orleans is 7 feet below sea level and that Oklahoma City is

Phoenix [80]

Above means positive
Below means negative

New Orleans is 7 feet 'Below", so elevation is -7 ft.

Auditoriums are often designed so that are fewer seats per row for rows closer to the stage. Suppose you are sitting in row 18 i

zhannawk [14.2K]

Answer:

(a) $22$ (b) $109$

Step-by-step explanation:

GIVEN: Auditoriums are often designed so that are fewer seats per row for rows closer to the stage. Suppose you are sitting in row $18$ in an auditorium and notice that there are $73$ seats in your row. It appears the row in front of you has $70$ seats and the row behind you has $76$ seats. Suppose this pattern continues throughout the auditorium.

TO FIND: a) How many seats are in the first row b) How many seats are in the $30th$ row?

SOLUTION:

total seats in $row_{19}=76$

total seats in $row_{18}$ $=73$

total seats in $row_{17}=70$

as it clearly form an A.P. with $d=76-73=3$

(a)

let total seat in first row be $a$

as total seats in $row_{18}=73$

$row_{18}=a+(n-1)d$

$73=a+17\times3$

$a=22$

total seats in first row are $22$

(b)

total seats in $30th$ be $x$

$x=row_{1}+(30-1)3$

$x=22+29\times3$

$x=109$

total seats in $30th$ row are $109$

Use technology to solve for x. 3^x - 4= 6x - 7

Anuta_ua [19.1K]

Answer:

$x=1,1$

Step-by-step explanation:

$3x^2 - 4= 6x - 7$

For the given equation :

Making the coefficients of x to L.H.S

$3x^2-6x-4+7$ $=0\\$

$3x^2-6x+3=0$

Taking 3 as common from the above equation

$x^2-2x+1=0$

Splitting the equation to make factors

$x^2-x-x+1=0$

Taking common from the equation:

$x(x-1)-1(x-1)\\(x-1)(x-1)=0$

Equating 'x' to zero

$x=1,1$

For g (2) = 3x – 2 find the value of x<br> -<br> for which g(x) = 10

hram777 [196]

Answer:

For g (2) = 3x -2 find the value of x

The value of x is 2

for which g(x) = 10?

10 = 3x -2

10 +2 = 3x

12 = 3x

x = 12/3

x = 4
