- Vertex Form: y = a(x - h)^2 + k, with (h,k) as the vertex.
So firstly, plug the vertex into the vertex form: 
Next, we first need to solve for a. Plug (0,-6) into the equation to solve for a as such:
<u>Now we know that our equation is y = 3(x - 1)^2 - 9.</u>
Now to solve for the zeros (x-intercepts). Set y to 0 and add 9 to both sides of the equation: 
Next, divide both sides by 3: 
Next, square root both sides: 
Next, add 1 to both sides: 
<u>Your x-intercepts are (-0.73,0) and (2.73,0), or B.</u>
Answer:
Step-by-step explanation: the first is m the second one is 15x+5
Answer:
2.8 pages in one minute ( 3 pages if rounded)
Step-by-step explanation:
14 pages in five minutes
therefore one minute=
14÷5=2.8 pages /3
3 + 0.75x = 5.25 - 0.25x
0.75x = 2.25 - 0.25x
x = 2.25
3 + 0.75(2.25) = 5.25 - 0.25(2.25)
3 + 1.6875 = 5.25 - 0.5625
4.6875 = 4.6875
They are equal
The product of two even numbers is even.
Let m and n be any integers so that 2m and 2k are two even numbers.
The product is 2m(2k) = 2(2mk), which is even.
Things to think about:
Why didn’t I just show you by using any two even numbers like the number 4 and the number 26?
Why did I change from "m" to "k" ? Are they really different numbers or could they be the same?
Why did I specifically say that m and k were integers?
The product of two odd numbers is an odd number.
Let m and k be any integers. This means that 2m+1 and 2k+1 are odd numbers.
The product is 4mk + 2m + 2k + 1 (hint: I used FOIL) which can be written as
2 ( 2mk + m + k ) + 1 which is an odd number.
