2 feet per year. Its rise over run so you look for when the line perfectly intersects the end of a box and that happens every time you go up by 2 and across by one
Answer:
Step-by-step explanation:
Using the rule of exponents
× = , then
× = =
Remark
You are using the midpoint formula. Instead of finding the midpoint, you are looking for one of the points, so you have to rearrange the formula a little bit.
Givens
Midpoint (4,2)
One endpoint (6,1)
Object
Find the other endpoint.
Formula
m(x,y) = (x1 + x2)/2, (y1 + y2)/2)
Solution
Find the x value
4 = (6 + x2)/2 Multiply both sides by 2
4*2 = 6 + x2 Subtract 6 from both sides.
8 - 6 = x2
x2 = 2
Find the y value
2 = (1 + y2)/2 Multiply by 2
4 = 1 + y2 Subtract 1 from both sides.
4 - 1 = y2
y2 = 3
Conclusion
R(x,y) = (2,3)
Answer:
The axis of symmetry is at x=-2
Step-by-step explanation:
The axis of symmetry, h , is found at
h = -b/2a where a and b are the coefficients of the equation in standard form
y = ax^2 +bx +c
y = x^2 +4x+5
a =1 b=4 c=5
Then
h =- 4/2(1)
= -2
The axis of symmetry is at x=-2
