use FOIL (first, outside, inside last)

4a * 3a = 12a²

4a * -8 = -32a

-6 * 3a = -18a

-6 * -8 = 48

-12a² - 32a - 18a + 48

combine like-terms: -12a² -50a + 48

Compare the function with the parent function. Without graphing, what are the vertex, axis of symmetry, and transformation of th
Alex73 [517]

Answer: (1/3,-7); x=1/3; translated to the right 1/3 unit and down 7 units

Step-by-step explanation:

The parent function is:

g(x) = IxI

And we have:

f(x) = I6x - 2I - 7

We canr rewrite f to get:

f(x) = 6*Ix - 1/3I - 7

Then, now let's define some transformations:

If we start with g(x), a translation of N units to the right is:

f(x) = g(x - N)

if we start with g(x), a translation of N units up is:

f(x) = g(x) + N

A translation down would be:

f(x) = g(x) - N

And a vertical dilation of scale factor A is written as:

f(x) = A*g(x)

Then in this case we have:

A translation to the right of 1/3 units.

A dilation of scale factor 6.

A translation down of 7 units.

And the axis of symmetry will be when the absolute value part is equal to zero, or when

6*Ix - 1/3I = 0

And that is when x = 1/3.

Then the correct option is:

(1/3,-7); x=1/3; translated to the right 1/3 unit and down 7 units

Find the slope of the line n perpendicular to line h and through point P. Type your answer as a fraction in lowest terms.
vekshin1

Step-by-step explanation:

let the point be (h,k)

for a given line, ax+by+c

d=∣∣∣ah+bk+ca2+b2−−−−−−√∣∣∣

so, 2≤d1p+d2p≤4

2≤∣∣∣h−k2–√∣∣∣+∣∣∣h+k2–√∣∣∣≤4

22–√≤|h−k|+|h+k|

ifh>k

22–√≤h−k+h+k≤42–√

2–√≤h≤22–√

ifh<k

22–√≤−h+k+h+k≤42–√

2–√≤k≤22–√

area of shaded region

area = (22–√)2−2–√2
