Hello there!
To solve this system using substitution, notice that you already have one variable, x, solved for:
x=5-3y
Now, plug 5-3y in place of x in the other equation, -6x+5y=16:
-6(5-3y)+5y=16
Now simplify:
-6(5-3y)+5y=16
-30+18y+5y=16
-30+23y=16
23y=46
y=2
Now that you have y=2, plug this value in place of y into any of the two equations to solve for x:
x=5-3(2)
x=4-6
x=-1
Therefore, your final answers are that x=-1 and y=2 or (-1,2)
Answer:
$77
Step-by-step explanation:
The answer is $77 because first you need to find how much money was discounted by doing 70-49 to get 21. Then you need to find how much percent 21 is of 70 by doing 21/70, then you would get 0.3 which is 30% since you have to multiply it by 100. This means that there is a 30% discount. Then you would do 0.3*110=33. This means that the 30% discount takes away $33. So 110-33=77. The answer is $77.
Rise over run, so if the line had a slope of 3/5 you would go up 3 and over 5 to plot your next point. I hope this helped <3
Answer:
AC = 15
Step-by-step explanation:
Use segment addition postulate to add AB + BC = AC. 10 + 5 = 15.
(drawing out the line helps you visualize the problem better)
I believe it would be B. linear because it would depend on how much of a decrease the monthly rate changes and based on that the five hundred would change per every dollar (new customers=500x+5000) x being $decrease in monthly rate
