Answer:

4x -9

Step-by-step explanation:

First, expand it by multiplying (x+4) with -2.

(x + 3) - 2(4 + x) + 5x - 4

= x + 3 - 8 - 2x + 5x - 4

Then, collect like terms. Add up the coefficient of x, and the whole numbers separately.

= x - 2x +5x + 3 -8 -4

= 4x -9

When nothing can further be simplified, you get the answer.

Find the equation of a line perpendicular to −4x+4y=4 that contains the point (−4,5).
kati45 [8]

Answer:

y = - x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange - 4x + 4y = 4 into this form by adding 4x to both sides

4y = 4x + 4 ( divide all terms by 4 )

y = x + 1 ← in slope- intercept form

with slope m = 1

given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{1} = - 1, thus

y = - x + c ← is the partial equation

To find c substitute (- 4, 5) into the partial equation

5 = 4 + c ⇒ c = 5 - 4 = 1

y = - x + 1 ← equation of perpendicular line
