You first do -2(x+1) to get 5-2x-2=13
then you do 13-5= 8, then 8+-2=6
so then you have -2x=6
then -x= 3 and you have to times by -1 on both sides to get rid of -x
so the answer would be x=-3

The slope of a line is -4 and it’s y-intercept is (0,4) what is the equation of the line that is perpendicular to the first line
Rasek [7]

Original line equation: y=-4x+4

Perpendicular lines have opposite reciprocals, so the slope of the perpendicular line would be 1/4x.

Perpendicular line equation: y=1/4x+b

Plug in the coordinates that the line passes through to solve for b. Plug -8 in for x and 2 in for y.

2=1/4(-8)+b

Multiply.

2=-2+b

Add 2 to both sides.

4=b

Equation of the perpendicular line: y=1/4x+4

Hope this helps! :)

Scorpion4ik [409]
<span>Given number: Two hundred billion in half, how to write this one in standard form
let us first simplify each statement:
=> two hundred billion = 200 000 000 000
=> in half meaning = half of the given number or divide the given number by 2 to get the answer
=> 200 000 000 000 / 2
Show, the ½ of two hundred billion in standard form
=>  Thus, two hundred billion in half is equals to 100 000 000 000
