Answer:
Quadrant 2
Step-by-step explanation:
Quadrant 2 has a negative x value and a positive y value.
Answer:
Step-by-step explanation:
x + 5y = 8x - 20
5y = 8x - x -20
5y = 7x - 20
y = 7x/5 - 20/5
y = 7x/5 - 4
k/2+1/2=3
Move +1/2 to the other side. Sign changes from +1/2 to -1/2
k/2+1/2-1/2=3-1/2
k/2=3-1/2
Find the common denominator for 3 and -1/2.
Common denominator is 2
k/2=3(2)-1/2
k/2= 6/2-1/2
k/2=5/2
Multiply k/2 with 2. Multiply 2 with 5/2
k/2 (2/1)=2(5/2)
Cross out 2 and 2. Divide by 2. Cross out 2 and 2 for 5/2(2). Divide by 2
k=5
