Solve for equation4y+4=3x

Basile [38]

Answer:

Step-by-step explanation:

Switch sides:

3x = 4y+4

Divide both sides by 3:

$\frac{3x}{3}=\frac{4y}{3}+\frac{4}{3}$

Simplify to give:

$x=\frac{4y+4}{3}$

Carrie and brent leave home at the same time. carrie drives due east at a rate of 30 mph, while brent drives due south at a rate

Helga [31]

<h3>They are 268 miles far apart after 4 hours</h3>

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

$\large {\boxed {a = \frac{v - u}{t} } }$

$\large {\boxed {d = \frac{v + u}{2}~t } }$

<em>a = acceleration ( m/s² )</em>

<em>v = final velocity ( m/s )</em>

<em>u = initial velocity ( m/s )</em>

<em>t = time taken ( s )</em>

<em>d = distance ( m )</em>

Let us now tackle the problem !

<u>Given :</u>

v₁ = 30 mph due east

v₂ = 60 mph due south

t = 4 hours

<u>Unknown :</u>

displacement = d = ?

<u>Solution :</u>

$d_1 = v_1 \times t$

$d_1 = 30 ~ mph \times 4 ~ h$

$d_1 = \boxed {120 ~ miles}$

$d_2 = v_2 \times t$

$d_2 = 60 ~ mph \times 4 ~ h$

$d_2 = \boxed {240 ~ miles}$

$d^2 = (d_1)^2 + (d_2)^2$

$d^2 = 120^2 + 240^2$

$d^2 = 72000$

$d = \sqrt{72000}$

$d = 120\sqrt{5} ~ miles$

$d \approx \boxed {268 ~ miles}$

BRAINLIESTTT ASAP! PLEASE HELP ME :)

MaRussiya [10]

Answer:

(11, -13)

Step-by-step explanation:

A is at (3, -5) and B is at (13, -15)

A point that is ⅘ of the way from A to B also divides the differences of the x-and y-coordinates in the same ratio.

For the x-coordinate,

x₂ - x₁ = 13 - 3 = 10

⅘ × 10 = 8

3 + 8 = 11

The x-coordinate of the point is x = 11.

For the y-coordinate,

y₂ - y₁ = -15 - (-5) = -15 + 5 = -10

⅘ × (-10) = -8

-5 + (-8) = -13

The y-coordinate of the point is at y = -13.

The coordinates of the point are then (11, -13).

The diagram below shows the point ⅘ of the way from A to B.
