Passes through (1,12) and has a vertex (10,-4)
agasfer [191]

Answer: 16/81 (x-10)^2 -4

Step-by-step explanation:

To write a vertex equation with just a point and the vertex, you have to figure out the variables.

In vertex form, the equation is y = a (x-h)^2 + k

Your y is 12, x = 1, h = 10, and k = -4

Plug everything into equation

12 = a (1 - 10)^2 -4

12 = a (-9)^2 - 4

12 = 81a - 4

16 = 81a

16/81 = a

Now you know what the 'a' value is.

If you graph 16/81 (x-10)^2 -4 , you will get a point at (1,12) and a vertex of (10,-4)!

I hope this helps!

How to do this question plz ​
enyata [817]

Answer:

  x = 10

Step-by-step explanation:

Use the Pythagorean theorem. The sum of the square of the sides is the square of the hypotenuse.

  x² +(√200)² = (√300)²

  x² = 300 -200

  x = √100 = 10

The length of the unknown side is 10 units.

the length of a rectangle is 1 inch more than twice its width. if the perimeter of the rectangle is 74 inches, find the dimensio
Tatiana [17]
L = 2W + 1..................(1)
2L + 2W = 74
2L = -2W + 74..............(2)   Adding  (1) and (2):-

3L = 75
L = 75/3 = 25

W = (25 - 1) / 2 = 12

length is 25 inches and width = 12 inches
