Answer:
y=5, x=-2
Step-by-step explanation:
From the graph (attached), we can see that y=5, x=-2.
We can also solve system through algebra. (the easier and faster way)
y=1/2x+6
y=-1/2x+4
Substitute y with the first equation.
1/2x+6=-1/2x+4
1/2x+1/2x=4-6
x=-2
Then, substitute x with -2 in the equation.
y=1/2(-2)+6
y=-1+6
y=5

Answer:
1.18b
Step-by-step explanation:
Jacob had lunch at a restaurant and his bill was b.
Now, Jacob leaves 18% of his bill amount as a tip.
So, the tip amount at the rate of 18% of the bill amount will be
Therefore, the total cost of Jacob for the lunch will be b + 0.18b = 1.18b. (Answer)
