Answer:
first, subtract 17 on both sides: x²+2x-16=0
this cannot be factored, so use the quadratic formula to solve for x:
b²-4ac=2²-4(10(-16)=4+64=68
√68=2√17
so x=(-2+2√17)/2 or x=(-2-2√17)/2
x=-1+√17 or x=-1-√17
Step-by-step explanation:
4/6*2=8/12 so 11/12-8/12 is 3/12 or 1/4
Subtract 3 from both sides:
2/3z=4
divide by 2/3 on both sides (multiple 3/2 on both sides)
z= 6
ANSWER
True
EXPLANATION
We want to find the equation of the axis of symmetry of the given function:

The axis of symmetry of the function is given by:

where b = coefficient of x
a = coefficient of x²
From the given function:

Therefore, the equation for the axis of symmetry of the function is:

Therefore, it is true.
