PLEASE ANSWER I WILL RANK AND THANK

X + 4y = 9   Convert to  slope / intercept form:-

y  = (-1/4)x + 9/4

so the line perpendicular to this will have a slope -1 /(-1/4) = 4

so our equation will be y - y1 = 4(x - x1) where x1y1 is a point on the line.
x1 = 8 and y1 = -3:-
y - -3 = 4(x - 8)

y = 4x - 35
-4x + y = -35 is the answer

What is the equation of the graphed line written in standard form? 2x – y = –4 2x – y = 4 y = 2x – 4 y equals StartFraction one-
svp [43]

Answer:

The answer is "2x-y=4"

Step-by-step explanation:

Given:

2x-y=-4\\2x-y=4\\y=2x-4\\y=\frac{1}{2}(x-4)\\

The Formula of Slope:

m=\frac{y_2-y_1}{x_2-x_1}

by replacing the (2,0) and (0,-4) coordinates in the above formula:

\to m= \frac{-4-0}{0-2}\\\\ \to  m= \frac{-4}{-2}\\\\ \to  m= \frac{4}{2}\\\\ \to m= 2\\\\

if point y intercepting in x then x=0, for this the value of x= 0 and c=-4.

Equation of the line:

\to  y=mx+c

apply m and c value in the above equation:

\to  y=2x-4\\

Subtract by 2x on both sides of the equation we get:

\to  y-2x= 2x-4-2x\\\\\to  y-2x=-4\\\\\boxed{\boxed{2x-y=4}}\\\\

Solve the inequality 2x + 8 < 5x − 4.
Lana71 [14]

The solution to this inequality is 4 < x or x > 4.

In order to solve this, follow the steps to solving an equation with one variable. The steps are below for you.

2x + 8 < 5x - 4 ------> Subtract 2x from both sides

8 < 3x - 4 -----> Add 4 to both sides

12 < 3x -----> Divide both sides by 3

4 < x

What is the value of x in the equation 2<br> (4x+)-(3x+2)- 8(9-x) = x
Readme [11.4K]

Answer:

open the bracket

(4X+)-3X-2-72+X=X

4X+(-3X)-74+X=X

X-74+X=X

2X-74=X

then collect the term

-74=X-2X

-74=-X

divide by negative every side then you get

X=74
