Answer:
Vertex form:
The vertex is ![(-\frac{1}{2},-\frac{29}{4})](https://tex.z-dn.net/?f=%28-%5Cfrac%7B1%7D%7B2%7D%2C-%5Cfrac%7B29%7D%7B4%7D%29)
Step-by-step explanation:
For a general quadratic function the form is:
For the function
The values of the coefficients for the function are the following:
,
,
Take the value of b and divide it by 2. Then, the result obtained squares it.
Add and subtract
Write the expression of the form
The vertex is (h, k)
The vertex is: ![(-\frac{1}{2},-\frac{29}{4})](https://tex.z-dn.net/?f=%28-%5Cfrac%7B1%7D%7B2%7D%2C-%5Cfrac%7B29%7D%7B4%7D%29)
Answer:
0
Step-by-step explanation:
Its equal to something multiplied by 0 so it is 0
area of tile = 6 *14 = 84 square inches
number of tiles = 8500/84 = 101.19
102 tiles are needed
Does 0.007/10=0.07
true or false?
Answer:
NO if you wanted to get 0.07 you would have to multiply not divide.
Step-by-step explanation:
0.007/10=0.0007
6
Step-by-step explanation:
area of 1 rectangle= area of 2 rectangle
x(x+4) = (2x+3)(x-2)
x² + 4x = 2x² - 4x + 3x - 6
x² + 4x = 2x² - x - 6
x² + 4x - 2x² + x + 6 = 0
-x² + 5x + 6 = 0
x² - 5x - 6 = 0
x² - 6x + x - 6 = 0
x(x - 6) + 1(x - 6)=0
(x+1)(x-6)=0
x = 6,-1
