To find X:
-b/2a=-2/2(-2)=.5
plug in .5 to the equation to find y.
-2(.5)²+2(.5)+1
=1.5
Vertex: (.5,1.5)
Axis of symmetry:
x=.5
The answers are n = 49, x = 59 and y = 9.
<u>Step-by-step explanation</u>:
Keep the unknown terms on one side and constant terms on other side to solve the given expressions.
1) Solve 67=n +18
n = 18 - 67
n = 49
2) Solve x-16=43
x = 43 + 16
x = 59
3) Solve 54=6y
6y = 54
y = 54/6
y = 9
