Answer:
B
Step-by-step explanation:
Replace the second equation y=3x+4 into the first one:
2(3x+4)+5x=30
Now solve for x:
6x+8+5x=30
11x=30-8
11x=22
x=22/11
x=2
Finally, replace x=2 into y=3x+4
y=3*2+4
y=6+4 = 10
So the anwer is x=2, y=10
This easy asl i got u tho

Answer:
Karl prepared 30 liters in 5 hours
Step-by-step explanation:
The total amount of juice Karl prepares per unit time can be expressed;
T=U×h
where;
T=total number of liters of juice prepared
U=number of liters prepared per unit time
h=number of working hours
In our case;
T=12 liters
U=U
h=2 hours
replacing;
12=U×2
2 U=12
U=12/2
U=6 liters per hour
The unit rate=6 liters per hour
Solving for 5 hours
Total quantity of juice prepared=Unit rate×number of hours worked
where;
Unit rate=6 liters per hour
Number of hours worked=5 hours
replacing;
Total quantity of juice prepared=(6×5)=30 liters
Karl prepared 30 liters in 5 hours
Answer: y=-5
Step-by-step explanation:
A horizontal line appears on the graph if it goes through the y-axis. Knowing this, the coordinate tells us that the y-coordinate is -5. This tells us that the equation of the line is y=-5.
