<h3>I'll teach you how to solve (1/5x-4+2y)+(2/5x+5-4y)</h3>

-----------------------------------------------------------------

(1/5x-4+2y)+(2/5x+5-4y)

Remove parentheses:

1/5x-4+2y + 2/5x+5-4y

Group like terms:

1/5x+2/5x+2y-4y-4+5

Add similar elements:

3/5x+2y-4y-4+5

Add similar elements:

3/5x-2y-4+5

Multiply:

3x/5-2y-4+5

Add subtract the numbers:

3x/5+1-2y

Your Answer Is 3x/5+1-2y

Will give brainliest NEED HELP can some explain how to do this THANKS :D
arlik [135]

Answer:

(x + 13, y + 7)

Step-by-step explanation:

Hello there!

In order to find what the translation rule is, we need to find how much it move to the right/left and up/down

In this case, the line segment VW moved up 7 and to the right by 13

We can get this by checking how far apart the points are

I checked how far apart V and V prime

(V prime is the green V. When a point is primed, its just saying that the point has gone through translation, rotation, dilation, or reflection)

V is 13 units to the left of V prime and 7 units below V prime

This means that, to go from line VW to line V prime W prime, you need to shift the line up 7 units and to the right 13 units

So, the translation rule is (x + 13, y + 7)

*If you don't understand, tell me in the comments, I will try to explain further to your understanding. Thank you, and have a great rest of your day :)*

A curve passes through the point ????0, 5???? and has the property that the slope of the curve at every point P is twice the y-c
Angelina_Jolie [31]

Answer:y=2x^2

Step-by-step explanation:

Given Curve passes through \left ( 0,5\right )

Also the slope of the curve at every point p is twice the Y-coordinate of p

Let the coordinate of p be\left ( x,y\right )

Therefore

\frac{\mathrm{d} y}{\mathrm{d} x}=2y

\frac{dy}{y}=2dx

Integrating both sides

\int \frac{dy}{y}=\int 2dx

\ln y=2x+c

Substituting values

\ln 5=c

\ln \frac{y}{5}=2x

y=2x^2

Two missiles are initially 5000 miles apart. They travel along a straight line directly towards one another, one traveling at 20
Goshia [24]

d = 5,000 mi the distance between the missiles

v1 = 2,000 mph the rate of the first missile

v2 = 1,000 mph the rate of the second missile

t = 1 min = 1/60 hr

Since distance = speed*time the distance 1 minute before the impact is:

v1t + v2t = t(v1 + v2) = (1/60)(2,000 + 1,000) = 50 miles.

Alice and Bob are currently 1000 feet apart and are both running directly
zepelin [54]

The distance the bird has flown by the time Alice and Bob meet is 40 feet.

Given that the distance between Alice and Bob is 1000 feet and their running speed is 10 feet per second and the speed of bird is 20 feet per second.

Distance equals speed multiplied by time.

Distance between Alice and Bob=1000 feet.

Distance between the bird and Bob=1000 feet.

Speed of Alice and Bob=10 feet per second.

The combined speed of Alice and Bob=20 feet per second.

Since the two are running directly toward each other the distance each will cover at the meeting point is 50 feet (1000/20)

The time covered at the meeting point=20 second (1000/50)

Speed of the bird=20 feet per second.

The distance covered by the bird towards Bob at their meeting point is 40 feet(20 feet*20 seconds).

Hence the distance the bird has flown by the time Alice and Bob meet is 40 feet.
