Answer:
a=0
b may be 0 but is not required to be
Step-by-step explanation:
The y-axis corresponds to the line x=0. Any point on the y-axis will have an x-coordinate of 0.
If (a, b) is on the y-axis, then a = 0.
If the intersection point is (0, 0), then b=0. Otherwise, b is not 0.
Answer:
the chances are 1/4
Step-by-step explanation:
you have 1/4 chance you will pick the two angles that make 180 degrees or supplementary
Answer:
Step-by-step explanation:
y=-2x-4
y=5x+5
------------
-2x-4=5x+5
-2x-5x-4=5
-7x-4=5
-7x=5+4
-7x=9
x=9/-7
x=-9/7
y=5(-9/7)+5
y=-45/7+35/7
y=-10/7
Answer: x=-9/7, y=-10/7. (-9/7, -10/7).
----------------------------------------------------
-3x+y=8
2y=6x-10
----------------
6x-2y=10
-3x+y=8
-------------
y=8-(-3x)=8+3x
6x-2(8+3x)=10
6x-16-6x=10
-16=10
no solution
Answer: No Solution
--------------------------------
2y=4(x+3)
y-2x=6
--------------
y=4x+12
y=2x+6
--------------
4x+12=2x+6
4x-2x+12=6
2x+12=6
2x=6-12
2x=-6
x=-6/2
x=-3
y=2(-3)+6=-6+6=0
Answer: x=-3, y=0. (-3, 0).
-------------------------------------
x+2y=4
4x-2y=16
---------------
5x=20
x=20/5
x=4
4+2y=4
2y=4-4
2y=0
y=0/2
y=0
Answer: x=4, y=0. (4, 0).
