Answer:

y = 1/2x - 3/2

Step-by-step explanation:

The easiest way to find the inverse is to switch x and y and solve for y.

y = 2x + 3

x = 2y + 3 (Switch)

x-3 = 2y (Subtract y from both sides)

x/2 - 3/2 = y (Divide both sides by 2)

Answer:

The inverse is 1/2x -3/2

Step-by-step explanation:

y = 2x+3

To find the inverse, exchange x and y

x = 2y+3

Solve for y

Subtract 3 from each side

x-3 = 2y+3-3

x-3 =2y

Divide each side by 2

x/2 -3/2 = 2y/2

1/2x -3/2 =y

The inverse is 1/2x -3/2

In the scale used on a blueprint, 14
Sati [7]

Answer:

On the scale 24 feet represents 62.06 feet.

Step-by-step explanation:

In the given  scale:

14 inch represents 3 feet

Now, covert both the parameter into same length parameter.

1 inch  =  0.08333  feet

⇒14  inch =  14  x 0.08333 = 1.16 feet

or, by conversion  14 inch = 1.16 ft

Hence, on the given scale, (14 inch = 1.16 ft ) represents 3 feet.

Let us assume that  24 feet represents k ft on the scale.

Then by RATIO OF PROPORTIONALITY:

\frac{1.16}{3}   = \frac{24}{k}  \implies k = \frac{24 \times 3}{1.16}  \\= 62.06

Hence, on the scale 24 feet represents 62.06 feet.

What is two hundred sixty-five thousandths in standard form?
Debora [2.8K]

Answer:

10^-1*2.65

Step-by-step explanation:

two hundred sixty-five thousandths= 0.265

We need a number between 1 and 10, to do the multiplication in standard form, so 0.265 turns into 2.65.

Because 2.65 becomes, smaller we use a negative power. We only move the decimal place once to the left, so we would multiply 2.65 by 10^1.

10^-1*2.65=0.265
