Answer:
Step-by-step explanation:
You need to know:
Vertex form = 
The vertex is at
(h, k)
<u>Need to know about perfect squares </u>
<u>Need to know how to complete the square.</u>
-----------------------------------------------------------------------------------------
<u>To convert 
you need to complete the square on the equation.</u>
Complete the Square 
Divide -2 by 2 and then square it.
Add the one to the parentheses and subtract the one from the 5
Square 
Now we have
<u>Next add</u> -5 - 1 = -6
Our quadratic is in vertex form now.
Vertex form =
our equation =
Vertex = (1, -6)
point 1 = ( -1 , 5 ) point 2 = ( 5 , -5 )
equation of a line: y = mx + b
Find Slope (m):
( 5 - (-5)) / (-1 - 5))
= 10 / -6
= -3 / 2
slope = -3/2
Find y-intercept (b):
y = mx + b
y = -3/2 * x + b
5 = -3/2 * -1 + b <-------------- use the x and y coordinate of one of the . points. I used point 1 ( -1 , 5 )
b = 7/2 or 3.5
Assemble:
y = -3/2 * x + 3.5
4 x 7 divided by 9. Set 7 equal to 7/1. Now you have 4/9 x 7/1. Multiply numerators and denominators
Answer:
J.
Step-by-step explanation:
There is no solution because these are parallel lines.
Parallel lines never intersect and so they have no solution.
Answer:
"C"
Step-by-step explanation:
-B means the B is in the opposite direction
