Answer:

The inverse is 1/2x -3/2

Step-by-step explanation:

y =2x+3

Exchange x and y

x = 2y+3

Solve for y, subtracting 3 from each side

x-3 = 2y+3-3

x-3 =2y

Divide each side by 2

(x-3)/2 = 2y/2

1/2x - 3/2 =y

The inverse is 1/2x -3/2

Snowcat [4.5K]

$3 - \frac{2}{3} = 2 \frac{1}{3}$

$4 + \frac{2}{5} = 4 \frac{2}{5}$

$5 \div \frac{4}{7} = 8 \frac{3}{4}$

$\frac{4}{5} \times \frac{2}{3 } = \frac{8}{15}$

$\frac{1}{3} \div \frac{3}{5} = \frac{5}{9}$

HELP: Cho charges $1500 to build a small deck and $2500 to build a large deck. During the spring and summer, she built 5 more sm

Ludmilka [50]

Answer:

if she build x numbers of large decks, therefore small decks would be (x + 5)

1500*(x+5)+2500x =23500

1500x+7500+2500x=23500

4000x+7500 =23500

4000x=23500-7500

4000x=16000

x=4

4+5=9

cho built 4 large decks and 9 small decks
