Find the equation of the line thatis perpendicular to y =
contains the point (4,-8).
- 2/3 x

Answers

Answer:

y= 3/2x -14

Step-by-step explanation:

The formula to solve this problem is y- y1 = m(x-x1), so plug in the coordinates according to the formula: y-(-8)= m(x-4). Then, find the reciprocal of the slope, which is 3/2. Plug 3/2 to where the slope belongs: y+8=3/2(x-4). Calculate to solve the rest: y =3/2x -14

Answers

Answer:

G is not a function

Step-by-step explanation:

Answer:

Step-by-step explanation:

something is represented as a function when none of the inputs (x) repeat, but the outputs (y) change. the graph for letter G has repeating x values, but the y values don't change when an x repeats. however, the graph for letter H has repeating inputs (x), but the outputs are different, even with the same input.

that's why parabolas aren't functions (if you know what those are).

hopefully that helps and isn't too confusing! if you need anything else, let me know! :)

Which formulas return TRUE, if the value in cell B4 is 12 and the value in C4 is 29?

____ and ____ return TRUE, if the value in cell B4 is 12 and the value in C4 is 29.

Answers

Step-by-step explanDAdadadad

Answer:

Pretty sure the Answer is:

=XOR(B4=12;C4<9) and =AND(B4=12;C>9) return TRUE, if the value in cell B4 is 12 and the value in C4 is 29.

Step-by-step explanation:

An =XOR function returns TRUE if any of the clauses in it are true, while an =AND function returns true only if both are true. Therefore, since in =XOR(B4=12;C4<9) B4 does equal 12, since this is an =XOR function. =AND(B4=12;C>9) is correct because B4 = 12 and C4 is greater than 9.

Hope this made some sense...

Answer:

53,760,970 households/year

Step-by-step explanation:

First step is to do 65,929,420 - 12,168,450 = 53,760,970

Now divide 53,760,970 by 20 since the difference in 1997 and 1977 is 20

53,760,970/20 = 2,688,048.5

So each year 2,688,048.5 people got cable.

But it would be 53,760,970/year because then you could divide it by how ever many years to see how many people got cable.

Hope this helps!!
