I don't really know how to do that or I just don't remember
Answer:
20
Step-by-step explanation:
4 multiplied by 5 is equal to 20. You substitute 5 for x.
Answer:
x=7 and y=2
Step-by-step explanation:
In this case, you want to use elimination
1. multiply the second equation by -1
5x + 3y = 41
2x + 3y = 20
turns into
5x + 3y = 41
-2x + 3y = 20
2. combine the equations
3x=21
3. solve for x
3x=21
3x/3=21/3
x=7
4. Now you want to plug x back into the original equation
5x+3y=41
turns into
5(7)+3y=41
5. Then solve for y
35+3y=41
35+3y-35=41-35
3y=6
3y/3=6/3
y=2
6. results
x=7 and y=2
Answer:
perpendicular
Step-by-step explanation:
since their gradients sati
X+Y=6. Y=6-X 2X-(6-X)=-12 2X-6+X=-12. 3X=-6. X=-2. Y=6-(-2). Y=8
SOLUTION: { (x,y) | (-2,8) }
