What are the solutions to the system of equations?

trasher [3.6K]

Answer:

A. (0, 6) and (−2, 0)

Step-by-step explanation:

The given equations are:

$y=x^2+5x+6$

and

$y=3x+6$

We equate the two equations to find their point of intersection;

$x^2+5x+6=3x+6$

We equate everything to zero to get;

$x^2+2x=0$

$x(x+2)=0$

$x=0,x=-2$

When x=0, y=3(0)+6=6

One solution is;

(0,6)

When x=-2,

y=3(-2)+6=0

Another solution is;

(-2,0)

Let’s say that you put a cup of cold water in one room and a cup of hot water in another room. Both rooms are room-temperature.

Nutka1998 [239]

The motion of molecules determines temperature. The faster the particles move, the higher the temperature will be.

A cold cup of water will warm up to room temperature because the energy of the air in the room transfers to the cold water to make the water molecules move faster. The energy goes from hot to cold. The energy transfer is due to the molecules colliding into one another.

The hot cup of water cools down because the energy of the water molecules leaks out to the surrounding air to warm up the air around it, which is why you can feel the heat of the steam of water.

As for why you can feel cold things, its because the energy from your hand moves toward the cold object (again energy going from hot to cold), which makes your brain perceive the cold object.

What are the domain and range of the function below?

Sonbull [250]

ANSWER

Domain:
$x \geqslant 0$

Range:
$y \leqslant 4$

EXPLANATION

The domain refers to the values of x for which the function is defined.

The least value of x is 0.

Therefore the domain is $[0,\infty]$ .

or

$x \geqslant 0$

The range refers to values of y for which x is defined.

The highest value on the y-axis that the graph can attained is 4. The function decreases without bound.

There the range is $(- \infty,4]$ .

or

$y \leqslant 4$

OleMash [197]

Answer:

x=2.25hrs

Step-by-step explanation:

1/9 =1/4hr

9/9=x

(9/9)/(1/9)=1/4.xhr

1/9=1/4.xhr

cross multiplying

4x=9

x=9/4

x=2.25hrs
