The function g(n)=n²-6n+16 represents a parabola.
goblinko [34]

Part A: (n^2-6n)+16

[(n^2-6n+9)-9]+16

(n-3)^2+7

Part B: From the above result,

Vertex (3,7) this is the minimum point of the graph since the coefficient of a is positive

Part C: The axis of symmetry is basically the x coordinate of the vertex, so the axis of symmetry is x=3

Hope this helps!

Write an equation of the line that passes through (1,2) and is perpendicular to the line y= 1/3x+4
zvonat [6]

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be perpendicular, their slopes have to be the negative reciprocal of each other. (Basically flip the sign +/- and the fraction(switch the numerator and the denominator))

For example:

Slope = 2 or \frac{2}{1}

Perpendicular line's slope = -\frac{1}{2}   (flip the sign from + to -, and flip the fraction)

Slope = -\frac{3}{4}

Perpendicular line's slope = \frac{4}{3}  (flip the sign from - to +, and flip the fraction)

y = 1/3x + 4        The slope is 1/3, so the perpendicular line's slope is -\frac{3}{1} or -3.

Now that you know the slope, substitute/plug it into the equation:

y = mx + b

y = -3x + b       To find b, plug in the point (1, 2) into the equation, then isolate/get the variable "b" by itself

2= -3(1) + b     Add 3 on both sides to get "b" by itself

2 + 3 = -3 + 3 + b

5 = b

y = -3x + 5

Factor the expression completely
Kisachek [45]

Answer:

2 ( 2x+3) (2x-3)

Step-by-step explanation:

8x^2-18Factor out the greatest common factor of 2

2( 4x^2 -9)

2 ( (2x)^2 - 3^2)

What is inside the parentheses is the difference of squares

a^2 - b^2 = (a+b)(a-b)  

2 ( 2x+3) (2x-3)

Please help, and plz don't be saying this is the right answer if u dont know for sure.
Andru [333]
It will be 9x + 1 = 12x + 20.

The answer you’ll put in the box is 1, because it doesn’t ask you to solve for x, just fill in the number.
