Answer 1

Answer:

6 Weeks

Step-by-step explanation:

20 + 10x = 50 + 5x

10x = 30 + 5x

5x = 30

x = 6

Answer 2

Answer:

6 weeks

Step-by-step explanation:

You can create linear equations to model this.

Science Club:

y = 10x + 20

Math Club:

y = 5x + 50

These can be solved using substitution:

5x + 50 = 10x + 20

-5x            -5x

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

50 = 5x + 20

-20         -20

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

30 = 5x

/5       /5

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

6 = X

Plug into one of the original equations:

y = 10x + 20

y = 10(6) + 20

y = 80

The point at which they intersect is: (6, 80)

Since X represents the number of weeks, it would be 6 weeks before they have the same balance.

Answer: y=x+8. let me knw if you need the explanation :)

Step-by-step explanation:

Answer:

y=x+8

Step-by-step explanation:

1. Use the slope formula to find slope

y2-y1/x2-x1

-12-5/-20--3

= -17/-17

= 1

2. Plug in the slope and of the coordinates into point-slope form

y-y1=m(x-x1)

y-5=1(x+3)

3. Distribute and add 5 to both sides.

y-5=1x+3

y=1x+8

The last choice is the correct answer (-1,-2)

Answer:

(-1,-2)

Step-by-step explanation:

D's original postion/location is at (1,-2)

You basically take the point D and keep your y coordinate, -2, the same /constant and change your x coordinate (flip the sign)

So keeping the y-coordinate constant, -2 changing positive 1 to negative 1

So.. D's location reflected on the y axis is (-1,-2)

*Let's Say: D was reflected on the x-axis you would do the opposite by keeping the x coordinate constant and flipping the y-coordinate sign (to positive)

So...

D's location reflected on the x-axis is (1,2)

Two large and 1 small pump can fill a swimming pool in 4 hours. One large and 3 small pumps can also fill the same swimming pool in 4 hours. How many hours will it take 4 large and 4 small pumps to fill the swimming pool? Please help me answer I'm in 5th grade and this is so hard.

Answers

Answer:

Let's define.

L = rate at which the large pump fills the pool.

S = rate at which the small pump can fill the pool.

We have two relations:

"Two large and 1 small pump can fill a swimming pool in 4 hours."

(2*L + S)*4h = 1

"One large and 3 small pumps can also fill the same swimming pool in 4 hours."

(L + 3*S)4h = 1

Then we have the system of equations:

(2*L + S)*4h = 1

(L + 3*S)4h = 1

To solve this system, we need to isolate one of the variables in one of the equations, i will isolate S in the first equation:

S = 1/4h - 2*L

Now we can replace that in the second equation:

(L + 3*(1/4h - 2*L))4h = 1

L + (3/4h) - 6*L = 1/4h

-5*L = 1/4h - 3/4h = -2/4h

L = (2/4h)*(1/5) = (2/20h) = 1/10h

This means that one large pump needs 10 hours to fill one pool.

With this, we can find the value of S:

S = 1/4h - 2*L = 1/4h - 2/10h = 5/20h - 4/20h = 1/20h

This means that a small pump needs 20 hours to fill a pool.

Now we can answer:

How many hours will it take 4 large and 4 small pumps to fill the swimming pool?

We need to solve the equation:

(4*(1/10h) + 4*(1/20h))*T = 1

We need to find the value of T.

T = 1/((4*(1/10h) + 4*(1/20h)) = 1.67 hours.

This means that 4 large and 4 small pumps need 1.67 hours to fill a pool.
