Substitute into second equation:
x+3=2x-3
put variables on one side:
3x=6
x=2
Substitute to find y:
y=2+3
y=5
So (x, y) = (2, 5)
P = 2a + b + c
Subtract 2a + b on both sides
c = P - (2a+b)
c = P - 2a - b
Hope that helps :)
0.7=7/10
0.8=8/10
0.75=3/4 this is between 0.7 and 0.8
Answer:
y =
x + 4
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 )
y = - 3x + 6 ← is in slope- intercept form
with slope m = - 3
given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, then
y =
x + c ← is the partial equation of the perpendicular line
to find c substitute (3, 5 ) into the partial equation
5 = 1 + c ⇒ c = 5 - 1 = 4
y =
x + 4 ← equation of perpendicular line
