Answer:
D
Step-by-step explanation:


Answer:
x=1
Explain:
y=2x^2−4x+1
dy/dx=4x-4
The line of symmetry will be where the curve turns (due to the nature of the
x^2 graph.
This is also when the gradient of the curve is 0.
Therefore, let
dy/dx=0
This forms an equation such that:
4x−4=0
solve for x,
x=1
and line of symmetry falls on the line
x=1
Answer:
x +16 = 118
Step-by-step explanation:
A number(unknown ) = x
Increased = +
Merge all together you have

Tip ; If you solve the equation you will get 102 as an answer. 102 +16 =118 .
SO the equation is correct .☻
