Answer:
{x,y} = {-2,2}
Step-by-step explanation:
Solve equation [2] for the variable y
7y = 7x + 28
y = x + 4
Plug this in for variable y in equation [1]
-8x + 4•(x +4) = 24
-4x = 8
Solve equation [1] for the variable x
4x = - 8
x = - 2
By now we know this much :
x = -2
y = x+4
Use the x value to solve for y
y = (-2)+4 = 2
Solution :
{x,y} = {-2,2}
and this intersects at only one point so your answer is A

It took 50 hours to produce 3 oz of honey.
<u>Step-by-step explanation:</u>
Rate of production= 1.5% per hour
Initial amount of honey = 4 oz
Final amount of honey = 7 oz
Honey produced = 3 oz
Amount produced = (initial amount x rate x time) /100
3 = (4 x 1.5 x t) /100
300 = 6t
t = 300/6
t = 50 hours
It took 50 hours for the bees to produce 3 oz of honey.
