Answer:
Parallel
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 )
given
4x + 2y = 10 ( subtract 4x from both sides )
2y = - 4x + 10 ( divide through by 2 )
y = - 2x + 5 ← in slope- intercept form
with slope m = - 2
and
y = - 2x + 15 ← is in slope- intercept form
with slope m = - 2
• parallel lines have equal slopes
then the 2 lines are parallel
Step-by-step explanation:
We know that
or
(1)
and
(2)
Let's move the P and V variables in Eqn(2) to the right side:
(3)
Substitute Eqn(1) into Eqn(3):
Answer:
x=-6
Step-by-step explanation:
2x-1=3x-7
2x-3x=-7+1
x=-6
Answer:
n= -3
Step-by-step explanation:
-3n+(-4)=5
add four to both sides.
-3n=9
divide both sides by -3.
n= -3
