put this solution on YOUR website!Hi nearlyhairless, lets see what we can do to:
Are the following lines parallel, perpendicular, or neither? L1 with equation x – 6y = 30 L2 with equation 6x + y = 6
A) Parallel
B) Perpendicular
C) Neither
Put the equations in slope intercept form:
, m=slope and (0,b)= y-intercept. Parallel lines have equal slopes and perpendicular lines have slopes that are negative reciprocals (opposite signs and upside down).
L1)
slope=m=+1/6
L2)
m=-6/1
(B) Perpendicular
:
Given
find f(0).
Let x=0
:
Given g(x) = 4x – 3, find g(3a).
Let x=3a
g(3a)=4(3a)-3
g(3a)=12a-3
:
Given f(x) = 4x + 4, find f(0)
let x=0
f(0)=4(0)+4
f(0)=0+4
:
Solve the system by addition.
L1) 5x – 3y = 13
L2) 4x – 3y = 11
Multiply L2 by -1 and add L1 and L2
-1(4x-3y)=-1(11)
-4x+3y=-11
-----------
5x-3y=13
-4x+3y=-11
____________
x+0y=2
x=2
Substitute x=2 into L1 and solve for x.
5(2)-3y=13
10-3y=13
-10+10-3y=-10+13
-3y=3
-3y/-3=3/-3
y=-1
The solution is (x,y)=(2,-1)
Happy Calculating!!!
