Answer:

Positive where x < -6 and x > 8.

Step-by-step explanation:

y = x^2 - 2x - 48

The graph of this is a parabola which opens upwards ( because the coefficient of x^2 ( = 1) is positive). So it will positive to the left and to the right of the points where  it passes through the x axis ( i e the zeros of the function).

x^2 - 2x - 48 =0

(x + 6)(x - 8) = 0

So the zeros are at x = (-6,0) and at (8, 0).

Therefore the intervals are  x < -6 and x > 8.

Find the slope of the line that passes through (1,6) and (4,4)
Vadim26 [7]

Answer:

y=-2/3x+20/3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(4-6)/(4-1)

m=-2/3

y-y1=m(x-x1)

y-6=-2/3(x-1)

y=-2/3x+2/3+6

y=-2/3x+2/3+18/3

y=-2/3x+20/3

4. ADEF is an equilateral triangle.<br> E<br> 24<br> 20<br> D<br> F
irinina [24]

By Pythagorean theorem

x²+GF²=EF² ( where G is the point of intersection of perpendicular lines)

now, GF=1/2 EF= 12

x²+12²=24²

x²=24²-12²

x²=432

x=√432

x=12√3

x≈20.78

Marina CMI [18]

Answer:

The minimum would be 4,500, and the maximum would be 4,700.
