Y-x=3
-y-4x=2 (I multiplied this equation by -1 so when I add I can eliminate a variable.)
Now add them together.
-5x=5
x=-1 now plug in x to solve for y
-y-4(-1)=2
y=2 so your answer is (-1,2)
Answer:
The correct answer is choice D.
Step-by-step explanation:
Since the parabola opens sideways, that means the function will feature and not , so you can immediately rule out options B and C. Because the graph also opens right, that means the coefficient of is positive. Using all of this information, you'll find that the correct answer is D: .
We won't be using the given point (-6,1), since it won't really help us to get our answer.
Add 2/3x to both sides of the equation.
The 2/3x on the left side will cancel each other out.
This equation is in the form y=mx+b, which is slope intercept form.

Answer:
Original Cost= $ 230
Price after Markup= $230*1.65 = $379.50
Price after Tax= $379.50*1.08= $ 409.86
