{y=-x+1<br> {y=4x-14<br> please help me <br> my paper is due today
Temka [501]

- x + 1 = 4x - 14 \\  - x - 4x =  - 14 - 1 \\  - 5x =  - 15 \\ x = 3

Substitute x = 3 in any given equations. I will do in y = - x + 1

y =  - x + 1 \\ y =  - 3 + 1 \\ y =  - 2

Therefore the answer is (3,-2)

4. Coach Kent brings 3 quarts of sports druk U
murzikaleks [220]

Answer:

6 ounces of the drink each player get.

Step-by-step explanation:

Given:

Coach Kent brings 3 quarts of sports druk U  soccer practice.

He gives the same amount of the  drink to each of his 16 players.

Now, to find ounces of the amount of drink each player get.

1 quart = 32 ounces.

So, 3 quarts = 32 × 3 = 96 ounces.

As given the amount of drink to each player get the same.

Thus, to get the amount of drink each player get we divide the amount of drink by number of players:

\frac{Amount\ of\ drink}{Number\ of\ players}

=\frac{96\ ounces}{16\ players}

=6\ ounces\ per\ players.

Therefore, 6 ounces of the drink each player get.

If the volume of a cube is increased by a factor of 10 (so that the new volume is 10 times the size of the original volume), by
Alexeev081 [22]

Answer:

surface area of cube 10^{\frac{2}{3} } time

Step-by-step explanation:

given data

new volume =  10 time original volume

to find out

what factor surface area change

solution

we consider here side of cube is a

and volume is V

we consider here a is 2

then volume will be v1 = a³ = 2³ = 8

and surface area = 6a²    = 6(2)² = 24    ..........1

so if volume increase 10 time

than

V = 10 × v1

a³ = 10 × 8

a³= 80

a = 2 × ∛10

and

surface area increase here

surface area = 6a²

surface area = 6( 2 × ∛10 )²

surface area = 24 × 10^{\frac{2}{3} }    ............2

so from equation 1 and 2

surface area / surface area = 24 × 10^{\frac{2}{3} }  / 24

surface area = 10^{\frac{2}{3} }

so here surface area of cube will be 10^{\frac{2}{3} } time

MaRussiya [10]

Answer:

No

Step-by-step explanation:

2 liters = 2,000

80/3 = 26.6

the bottle leaks 26.6 milliliters in a min

26.6 * 60 = 1596

1596 / 1000 = 1.596 ( to convert to liters)

the bottle will leak 1.596 an hour
