Answer:

C. 4/3x - 5

Step-by-step explanation:

First, to eliminate unnecessary answers, we can find out how to make sure the line will be perpendicular to -3/4. You will know if two lines are perpendicular if the slopes are COMPLETELY opposite. For example, 4/3 is COMPLETELY opposite from -3/4.

-3/4......4/3

So, now we know we eliminated two answers. We are left with A and C.

Then, I opened an online graphing calculator and found out which one of these lines pass through (12,9). Attached is a picture proving that answer C's line crosses through this point. Please mark me Brainliest; I need it to move on in my account! =D

8xy+4xy^2 what is the result ?

Molodets [167]

Answer:

4xy(2+y)

Step-by-step explanation:

Factor 4 x y out of 8 x y .

$4xy(2)+4xy^2$

Factor 4xy out of $4xy^2$

4xy(2) + 4xy(y)

Factor 4 x y out of 4 x y ( 2 ) + 4 x y ( y ) .

4xy(2+y)

How do you do #1- 3x + y = 17 4x + y = 18 find for x and y

daser333 [38]

1st multiply the top equation by -1 to get -3x - y = -17 then add the 2 equations together to get:

4x + y - 3x - y = 18 - 17
x = 1 (simplified down)

Now plug the 1 into either equation
4(1) + y = 18
4 + y = 18
y = 18 - 4 = 14

Your point is (1, 14)
