Multiply the second equation by 3
-4x+9y=9
3x-9y=-18
add the equations together
-x=-9 Simplify
x=9
now plug in your x value
(9)-3y=-6 Simplify
-3y=-6-9
-3y=-15
y=5
30,000-100%
2%(6)=12%
30,000/100(12)=3600
30,000-3600=26400 lion in Africa after 6 years
0.50
imagine it like a dollar.
1/4 of a dollar is 0.25
meaning 2/4 is 0.50
Answer:
A system of linear equations is just a set of two or more linear equations. In two variables (x and y) , the graph of a system of two equations is a pair of lines in the plane.
Step-by-step explanation:
The lines intersect at infinitely many points. (The two equations represent the same line.)
Answer:
Step-by-step explanation:
y + 2 = -1/2(x - 4)
y + 2 = -1/2x + 2
y = -1/2x
