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

Answers

Answer:

-1/3 is the slope of the line

Step-by-step explanation:

Answer:

[tex]-\frac{1}{3}[/tex]

Step-by-step explanation:

y = mx + b

m is the slope and b is the y-intercept.

Subtract x from both sides of the equation.

x - x + 3y = 10 - x

3y = 10 - x

Divide each term by 3.

[tex]\frac{3y}3y} = \frac{10}{3} + \frac{-x}{3}[/tex]

[tex]y = \frac{-x}{3} + \frac{10}{3}[/tex]

Rewrite in slope intercept form.

[tex]y = -\frac{1}{3}x + \frac{10}{3}[/tex]

Finding angle 1:

52 + angle 1 = 180

angle 1 = 128

Finding angle 2:

128 (angle 1) + angle 2 = 180

angle 2 = 52

Finding angle 5:

52 + 47 + angle 5 = 180

angle 5 = 81

Finding angle 3:

angle 2 + angle 3 + angle 5 = 180

52 + angle 3 + 81 = 180

angle 3 = 47

Finding angle 4:

angle 3 + angle 4 = 180 OR angle 4 + 47 = 180

47 + angle 4 = 180

angle 4 = 133

Lina works at shake shack which pays $9.25 an hour and the state takes 15% out of her salary for income taxes. She works 15 hours a week after school and on weekends for 5 weeks. How much is her paycheck a month?

Answers

Answer:

Lina should make $471.75 a month.

Step-by-step explanation:

If Lina makes $9.25 an hour and she works for 15 hours a week then you multiply those two numbers together. The resulting number is $555. Then you'll multiply that by .15 to find 15% of that number which is 83.25. After, you'll subtract that from $555, which gives you $471.75.

Jordan's dog weights p pounds. Emmett's dog weighs 50% more than Jordan's dog.
Which expressions represent the weight, in pounds, of Emmett's dog?

Answers

the expression fir the weight  of Emmett's dog is 1.25p

Step-by-step explanation:

The weight of Jordan's dog is p pounds.

And it has been given that Emmett's dog weighs 25% more than Jordan's dog.

Hence, 25% of weight of Jordan's dog is

25% of p

= 0.25p
