Equation: y = 6 - 2x
Fill in the x numbers in the x which is next to -2 —> y = 6 - 2(0), y = 6 -2(1), y = 6 -2(3), and etc.
A) 0 —> 6
1 —> 4
2 —> 2
3 —> 0
4 —> -2
5 —> -4
B) Put a dot on y axis on number 6, then go down by 2 because your subtracting 2
C) 6 - 2x = 3
-6 -6
-2x = -3
-2/-2 -3/-2
X = 1.5
For problem 2, you are correct in stating that a curve forms. Specifically, if we were to trace along the outer edge of the shape, then we'd form a <u>parabola</u> that has been tilted 45 degrees compared to the more familiar form that students are taught (where the axis of symmetry is vertical).
For more information, search out "Tangent method for parabolas". As the name implies, the tangent method draws out the tangents of the parabola which helps form the parabola itself.
Everything else on your paper is correct. You have problem 1 correct, and the table is filled out perfectly. Nice work.
A= 1
B= -5
C= 10
In order to figure it out, you can think about it like this..
Answer: 164.32 miles
Step-by-step explanation:
Given that:
Weekly coverage :
Miles biked to the river = 0.86 miles
Miles biked along the river back home =. 2.3 miles
Total miles biked weekly:
(0.86 + 2.3) miles = 3.16 miles weekly
Number of weeks per year = 52
Miles biked yearly : (number of weeks per year * miles biked weekly)
= 52 * 3.16 miles
= 164.32 miles
Mrs endo will bike about 164.32 miles in a year.
You do 28, which is the original cost, then you take that 15% off to do that you multiply 28×.15 and you get 4.2 and subtract that from original cost and you get 23.8 then to get the cost after tax you do 23.8×.0675 and you get 1.6 then you add that to 23.8 and get 25.4 dollars
