Answer:
The Answer is 6.5 because you are dividing by negative 2
Step-by-step explanation:
trollface quest is a mobile game.
The slope-intercept form of the equation of a straight line:
y=mx+b
m=slope
Therefore; in this equation (y=3x+5); m=3
a)
6x+2y=12
2y=-6x+12
y=-6/2 x + 12/2
y=-3x+6 ⇒ m=-3≠3 (this line is not parallel to "y=3x+5")
b)
-3x+y=8
y=3x+8 ⇒ m=3 (this line es parallel to "y=3x+5")
c)
3y=9x
y=9/3 x
y=3x ⇒ m=3 (this line is parallel to "y=3x+5")
d)
y=-x ⇒ m=-1≠3 (this line is not parallet to "y=3x+5")
Therefore; "-3x+y=8" and "3y=9x" are parallel to "y=3x+5".
Answer:
x=2°
Step-by-step explanation:
The given angles are corresponding angles.
Corresponding angles are congruent.
7x+9=9x+5
4=2x
x=2
X should be -1 and Y = 2
To make sure, plug in numbers
----------------------------------------------------------
-1 - 2 = -3 That works, now we try equation 2
-------------------------------------------------------------------------
x + (3)(2) = 5
-1 + 6 = 5
This works to
====================================================
X = -1 and Y = 2
