Answer:

perpendicular

Step-by-step explanation:

Let's find the slope of both lines

For line 3x-6y=-1

-6y=-1-3x

y=1/6+½x

m=½

For line 18x+9y=-14

9y=-14-18x

y=-14/9-2x

m=-2

m1•m2=½×-2=-1

since m1•m2=-1 the lines are perpendicular

The table represents a quadratic function. Write an equation of the function in standard form.
kakasveta [241]

The equation of the quadratic function in standard form as required in the task content is; f(x) = -x² + 12x - 43.

<h3>Standard form equation of a quadratic function.</h3>

It follows from the task content that the standard form equation of the quadratic function is to.be determined.

Since the standard form equation can be derived from the vertex form equation as follows;

f(x) = a (x - h)² + k

f(x) = a (x - 6)² - 7

Hence, to find the value of a, Substitute x = 8 and f(x) = -11 so that we have;

-11 = a (8 - 6)² - 7

-11 = 4a - 7

4a = -4

a = -1.

Hence, the equation in vertex form is; f(x) = -1 (x -6)² - 7 and when expressed in standard form we have;

f(x) = -1(x² - 12x + 36) - 7

f(x) = -x² + 12x - 43

Therefore, the required equation in standard form is; f(x) = -x² + 12x - 43.
