-5 + 6 = 1
Step-by-step explanation:
The model number may be used to simplify -5 + 6 = 1
Answer:
3+5=5+3
Step-by-step explanation:
Because the commutative property means 'flip-flop'
Hope this helps! = )
You would get $15 in total because 5x3=15.
Answer: x=-1
Step-by-step explanation:
the x value of the vertex = -b/2a if the equation is in "ax^2+bx+c" for
you are in luck
x value of the vertex = -4/4 = -1
the line of symmetry is a vertical line, and since it must pass through the vertex
line of symmetry: x=-1
Answer:
x = ± 
- 2
Step-by-step explanation:
x² + 4x = 4
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 4 + 4
(x + 2)² = 8 ( take square root of both sides )
x + 2 = ± ( subtract 2 from both sides )
x = ± - 2
