Answer:
y = 2/5x + 24/5
*View graph to see the lines*
Step-by-step explanation:
y = 2/5x - 1/2
Parrel lines have the same slope
y = mx + b
y = 2/5x + b
2 = 2/5(-7) + b
2 = -14/5 +b
5(2 = -14/5 +b)
10 = -14 + 5b
+14 +14
24 = 5b
/5 /5
24/5 = b
y = 2/5x + 24/5
Hope this helps!

Answer:
In 14 weeks, they will have the same earnings.
Step-by-step explanation:
y = 55x + 1300 -------- (1)
y = 25x + 1720 -------- (2)
(2) = (1)
55x + 1300 = 25x +1720
55x - 25x = 1720 - 1300
30x = 420
30x ÷ 30 = 420 ÷ 30
x = 14
