What is the line symmetry for the graph of y= -3x^2+12x-11

Answers

Answer:

The line of symmetry is x=2

Step-by-step explanation:

Given:y=-3x^2+12x-11

We are given a quadratic equation and to find the line of symmetry.

As we know the line of symmetry of parabola passes through the x value of vertex.

If vertex of parabola is (h,k) then equation of line of symmetry x=h

So, first we find the vertex of parabola.

For equation: y=ax^2+bx+c

x=-(b)/(2a)

For given equation, a=-3 and b=12

Therefore, x=-(12)/(2(-3))

x=2

Hence, The line of symmetry of given parabola is x=2
The answer to your question is x=2. what you want to do is find both the x values for your quadratic equation and then add them and divide by 2.

Which tables contain correct pairs of input and output values for the function ? Select all the correct answers.

Answers

The correct answer for the question that is being presented above is this one: "A rule is a function if each element in the domain goes to exactly one element in the range."

The following tables that contain correct pairs of input and output values for the function are the: 
(1) 
Input (x) -1.6 0.4 2.2 3.7
Output f(x) -5.5 2.5 6.75 10.75

Harriet wants to buy items worth $248.50. She is using a store coupon for 25 percent off her purchases. She has to pay 5 percent sales tax. Calculate the total cost of the items.

Answers

Starting price is : $248.50
Price with 25% off :
$248.50 x ( 1 - 0.25 ) = $248.50 x 0.75 = $186.375
After that she has to pay 5 % sales tax:
$186.375  x 1.05 = $195.70
Answer:
The total cost of the items is $195.70.

Answer:   $195.70
