Answer:

(-1, 3), (-2, 2) and (-5, -1) lie on the line.

Step-by-step explanation:

Let the equation of the line which is parallel to the given line is y = mx + c

Here m is the slope of line similar to the line given = (y - y')/(x - x')

Here (x, y) and (x', y') are (4, 2) and (-2, -4)

then m = (2+4)/(4+2) = 6/6 = 1

Now the equation of the line will be y = x + c

This line passes through point P(0, 4)

4 = 1×0 + c

c = 4

Therefore equation of the line will be

y = x + 4

Now we check for each point given in the question whether it lies on the line or not.

For (-4, 2)

y = (-4) + 4 = 0

Hence not lies on the line.

For (-1, 3)

y = (-1) + 4 = -1 +4 = 3

Hence (-1,3) lies on the line.

For (-2, 2)

y = (-2) + 4 = -2 + 4 = 2

Hence (-2, 2) lies on the line.

For (4, 2)

y = 4 + 4 = 8

Hence (4, 2) lies on the line.

For (-5, -1)

y = -5 + 4 = -1

Hence (-5, -1) lies on the line.

Therefore (-1, 3),(-2, 2) and (-5, -1) lie on the line.

An easy way to compute this is to find the equation of the line and plug each one of the points in for x and y, your answers would be (-2,2) (-1,3) and (-5,-1)

A North American river otter wants to cross the North Saskatchewan river. It can swim at a speed of 2.75 m/s. In that location,
insens350 [35]

Answer:

Step-by-step explanation:

time to cross will be the distance divided by the velocity in that direction.

a) t = d/v = 45/2.75 = 16.363636... 16.4 s

In the same time that the otter is swimming cross stream, the stream is also moving perpendicularly at its own pace.

b) d = vt = 2.5(16.36) = 40.9090... 40.9 m

As velocity is a vector, An observer on the bank would see the velocity as the vector addition of the cross stream and down stream velocities

c) v = √(2.75² + 2.5²) = 3.716517... 3.72 m/s  magnitude

  θ = arctan2.5/2.75 = 42.2736... 42.3° downstream of a line straight across

Los lados de un triángulo rectángulo tienen por medida tres números enteros consecutivos. Calcula los lados del triángulo.
elixir [45]

Answer:

Los lados del triángulo rectángulo miden 3, 4 y 5, respectivamente.

Step-by-step explanation:

Un triángulo rectángulo puede ser descrito mediante el teorema de Pitágoras, para el caso de tres lados representando tres números enteros consecutivos, tenemos que:

(n+2)^{2} = n^{2} + (n+1)^{2} (1)

Donde n es un número natural.

A continuación, expandimos la expresión y resolvemos:

n^{2}+4\cdot n +4 = n^{2} + n^{2} +2\cdot n + 1

n^{2}-2\cdot n -3 = 0

(n -3) \cdot (n+1) = 0

La única solución factible es n = 3. En consecuencia, los lados del triángulo rectángulo miden 3, 4 y 5, respectivamente.

If blueberries cost $4.00 per pound, how many pounds of blueberries can you buy for $1.00?
Masteriza [31]

If x is the number of berries you can buy with 1 dollar,

1 pound of blueberries = $4.00

x pound of berries = $1.00

Lets set up a proportion- because these are directly proportional- when there is more pounds of berries, it will cost more.

\frac{1}{4.00} = \frac{x}{1.00}

Cross multiply

4x=1

Divide both sides by 4 to isolate x

x=1/4 or $0.25
