Write the equation of a line passing through (-4.3) and perpendicular to -6x + 4y =-12.
1 answer:
Answer:
y=-2/3*x+1/3
Step-by-step explanation:
-6x+4y=-12
put into y=mx+b line equation
4y=6x-12
y=(6/4)x-(12/4)
y=(3/2)x-4
slope is 3/2
to find perpendiular line slope take the negative inverse.
-(2/3) = slope of perpendicular line
use line equation and solve for y-intercept (b)
3=(-2/3)*(-4)+b
3=8/3+b
b= 9/3-8/3 = 1/3 : 3 = 9/3 to allow for subrtaction of fractions.

Answer: 11
Step-by-step explanation:just trust me
7= 16 + 3x
7-16 = 3x
-9 = 3x
x = (-9)/(3)
x = -3
Answer:
hope it helps you to understand
let's set up an equation:
x-4=9
solve normally:
x=13
We need to see the "given system".
