Y² + 2 y - 2x - 3 = 0
x + 3 = y² + 2 y
2 x + 3 = y² + 2 x + 1 - 1
2 x + 3 = ( y + 1 )² - 1
2 x + 3 + 1 = ( y + 1 )²
Answer:
2 ( x + 2 ) = ( y + 1 )²
Answer:
Step-by-step explanation:
A=L x W So.. 36m x 23m = 828m Hope this helps
Remember that to solve an equation we need to isolate the variable in one side. To do it we can perform any mathematical operations we want as long as we perform the operations to both sides of the equation.
Let's solve our equation step by step
Step 1. Subtract
from both sides of the equation



Step 2. Subtract 3 from both sides of the equation


Step 3. Divide both sides of the equation by 




We can conclude that the next step is: subtract 3 from both sides of the equation.
Answer:
c. perpendicular line
Step-by-step explanation:
Axis of symmetry is the x value of the vertex
the x value of the vertex, in form
y=ax^2+bx+c is -b/(2a)
so
y=-5x^2-10x-15
a=-5
b=-10
x value of vertex is -(-10)/(2*-5)=10/-10=-1
x=-1 is axis of symmetry
