Answer:
Step-by-step explanation:
a coefficient is a number with a variable so yea. i also added some pics for it too
you good homie :)
Answer:
one solution, no solution, infinitely many solutions
Step-by-step explanation:
I rearranged the first equation into x=6-2y
plug that into the second equation
2(6-2y)-3y=26
12-4y-3y=26
12-7y=26
-7y=14
y=-2
Then you plug that into one of the equations
x+2(-2)=6
x-4=6
x=10
The solution to the first system is (10,-2)
the second system already has one equation as something equal to a single variable so you just plug that into the other one
4x-2(2x-4)=-6
4x -4x +8 =-6
8=-6
this is a false statement so the system of equation has no solution
Lastly I rearranged the first equation into y=2x-4 and then plug that in
6x-3(2x-4)=12
6x-6x+12=12
12=12
this statement is true so the system of equations has infinite solutions
Answer:
3x2−363
Step-by-step explanation:
Answer:
Step-by-step explanation:
Line 1: (1, a) and (5, −2)
slope of the line is
Line 2: (2, 8) and (−5, a + 7)
slope of the line is
when the lines are parallel then slopes are equal
cross multiply it
subtract 4a from both sides
divide both sides by 3
