Step-by-step explanation:
its kinda easy
Answer:
b=-7
Step-by-step explanation:
if you were supposed t solve for something else just comment and i'll come back :)
(next time state what ur solving for)
One equation is a multiple of the other, so you have an infinite solution set and for every x you pick you can find a matching y to fulfill both equations
this forms a line and any of its points is valid in the equation
Answer:
100
Step-by-step explanation:
200 + 6d = 800
Subtract 200 from each side: 6d=600
Divide 6 from each side: d=100
Solve the system of equations:
y=2x+2 ................(1)
y=-2x+a+1............(2)
for x and y
(1)-(2)
4x-a+1=0 => x=(a-1)/4
(1)+(2)
2y=a+3 => y=(a+3)/2
x>0 if (a-1)/4>0 => a>1
y>0 if (a+3)/2>0 => a>-3
For both x & y >0, we have the condition a>1.
Note that if a=1, then the intersection poin lies ON the x-axis, and therefore NOT in quadrant 1.
