Answer:

The coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are \mathbf{(13,\frac{-9}{2})}

Step-by-step explanation:

We need to find the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1)

The midpoint of line segment can be found using formula:

Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

We have x_1=14, y_1=-8, x_2=12, y_2=-1

Putting values and finding midpoint

Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint=(\frac{14+12}{2},\frac{-8-1}{2})\\Midpoint=(\frac{26}{2},\frac{-9}{2})\\Midpoint=(13,\frac{-9}{2})

So, the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are \mathbf{(13,\frac{-9}{2})}

The temperature of a liquid is decreasing at a constant rate. After two minutes of cooling it was 178 degrees and after 5 minute
enot [183]

Answer:

Step-by-step explanation:

If the liquid is cooling at a constant rate, then the equation for this is linear.  We can use the info given to find the linear equation for this situation.  We have 2 points: (2, 178) and (5, 154), where the x coordinate represents the time in minutes, and y represents the temperature.  We use these values in the slope formula:

m=\frac{154-178}{5-2}=-\frac{24}{3}=-8

Now we will use one of the points to finish writing the equation.  I chose (2, 178), but it doesn't matter which one you choose; they will both give you the same equation in the end.

y - 178 = -8(x - 2) and

y - 178 = -8x + 16 so

y = -8x + 196

If we are looking for the temp when the liquid starting cooling, then we are looking for the temp at time 0, or when x = 0 (sincce x is our time).

y = -8(0) + 196 so

y = 196

That's the temp of the liquid before it started any cooling.

Answer:

Option A

Step-by-step explanation:

Given function is,

f(x)=x^4-x^2-6

Hint: (-1=-3+2) and (-3)(2)=-6

f(x)=x^4-3x^2+2x^2-6

       =x^2(x^2-3)+2(x^2-3)

       =(x^2+2)(x^2-3)

f(x)=(x^2+2)(x^2-3) is the factored form of the given function.

Option A will be the correct option.

Answer:

x - 6

Step-by-step explanation:

I am unfamiliar with such algebra tiles, but logically that set of tiles tells me :

1 x, -1, -1, -1, -1, -1, -1

so,

1×x + 6×(-1) = x - 6
