Y=-x^2-2x+6 
To find the vertex I'm going to use the axis of symmetry formula: 
x=-b/2a 
x = 2/-2 
x = -1 
To find the y-value I'm going to plug in the x value in the above equation 
y=-(-1)^2-2(-1)+6 
y = -1+2+6 
y = 7 
The vertex is : 
(-1,7)

Answer:

The number of movies purchased is 5

Step-by-step explanation:

40.00 + 3.50 = 43.50

43.50 + 3.50 = 47.00

47.00 + 3.50 = 50.50

50.50 + 3.50 = 54.00

54.00 + 3.50 = 57.50

so if you add 3.50 to 40, 5 times you'll get 57.50

Hope it helped

Answer:

7 (units)

Step-by-step explanation:

If E is placed at the number 6- then it would take 6 to get to 0. If B is placed at -1, then it would be one more backward to get to B- so it would take 7 to get from E to B.

What is the value of the expression? Enter the answer in the box.<br> 4+(8 - 7) X6-1
e-lub [12.9K]
Answer: 9

Explanation: you would use PEMDAS to solve the algebraic expression first by doing parentheses so subtract 8 and 7 which leaves you with 4 + 1 times 6-1. You would then multiply 1 into 6 which would leave you with 4 + 6 - 1 which you would then sum up 4 and 6 which leaves you with 10-1 which would give you the answer of 9

So the answer would be 9

Hope this helps!

What is the standard form of the polynomial 4x+6y^3x-xy+xy^2
meriva

The required standard form is 6y^3x+xy^2-xy+4x

<h3>Polynomial function</h3>

Given the polynomial function expressed as:

  • 4x+6y^3x-xy+xy^2

We are to express this polynomial in standard form

To do that, we will write the degrees of the variables in descending order of magnitude as shown:

4x+6y^3x-xy+xy^2\\6y^3x+xy^2-xy+4x

Hence the required standard form is 6y^3x+xy^2-xy+4x
