Answer:

y = one-half x minus 1

Step-by-step explanation:

We are to find the inverse of a equation.

The given equation: y = 2x + 2

It is a linear equation: y = mx + b

To find its inverse of the equation, first we would interchange the position of the variables x and y

y = 2x + 2

x = 2y + 2

Then we make y the subject of formula.

x-2 = 2y

2y = x-2

y = (x-2)/2

y = x/2 - 2/2

y = x/2 - 1

Hence, the inverse of y = 2x+2 is

y = x/2 - 1

The inverse of y = 2x + 2 is y = one-half x minus 1

John leaves his home. He travels 5 blocks south and three blocks west. As the crow flies, how far is John from his home?
riadik2000 [5.3K]

Answer:

5.83 blocks away from his home

Step-by-step explanation:

If he travels 5 blocks south and 3 blocks west, the distance from his house considered along with the distances travelled gives a right angled triangle whose opposite side and adjacent sides are the distances travelled north and west.

The distance from his house after moving 3 blocks west is the hypotenuse side. As such, the distance may be computed using Pythagoras' theorem. Let the distance from his house be G

G^2 = 5^2 + 3^2

G^2 = 25 + 9

= 34

G = √34

=5.83

John is 5.83 blocks away from his home

Which equation represents the line with a slope of 5/6 that passes through the point (-2, 1)?
andreyandreev [35.5K]

Answer:

Step-by-step explanation:

Slope m = 5/6

The points (-2,1)

So; y1 = 1 and x1 = -2

The equation is y - y1 = m(x - x1)

y - 1 = 5/6(x + 2)

Multiply each term by 6

6y - 6 = 5(x + 2)

6y - 6 = 5x + 10

6y = 5x + 10 + 6

6y = 5x + 16

- 5x + 6y = 16

Multiplying by minus

5x - 6y = -16
