The First One ^What Is The Vertex For The Quadraticy = 2(x-3)^2 - 4? Type As (h.k)

Answers

Answer 1

Answer:

(3,-4)

Step-by-step explanation:

You can find the vertex where x = -b/2a

To find the values of a and b, it would be easier to write the equation in standard form, which is y = ax^2 + bx + c

y = 2(x^2 - 6x + 9) - 4

y = 2x^2 - 12x + 18 - 4

y = 2x^2 - 12x + 14

In this equation, a = 2 and b = -12.

So let's plug that into x=-b/2a

x = -(-12)/2(2)

x = 12/4

x = 3

Now we have the x, we can just plug that into the original equation and get the y coordinate for the vertex.

y = 2(x - 3)^2 - 4

y = 2(3 - 3)^2 - 4

y = -4

X - 11 < 7
Please help✨✨

Answers

x menos 11 menor que 7. .............................

Answer:

x < 18

Step-by-step explanation:

We have an inequality and are asked to solve.

To solve, we need to isolate x or by other means get x by itself.

X - 11 < 7

Add 11 to both sides :

x < 18

Now you could ask whether the inequality sign would change, no, this would only happen when you divide by a negative number.

Then you will have the equation 5-4x+4-2x-2

Next, just find your like-terms.

Your like-terms are 5,4,-2 and -4x, 2x

Then, for easier for calculation, just use the equation:

-4x-2x+5x+4-2

Your final answer should then be:

-6x+7

Write the equation for the inverse of the function.
y= Arctan (x+Pie/2)

Answers

Answer:

y = tan x - pi/2

Step-by-step explanation:

y = arctan(x+pi/2) use that tan y = x is y= arctan x

tan y = x+pi/2; change x with y and find y

tan x= y +pi/2; subtract pi/2 from both sides

-pi/2 + tan x = y

y= tan x -(pi/2) is the inverse function

you can also write it as

y = 1/2(2 tan x -pi)

y = tan x - pi/2
