Complete the statements below that show y = x2 + 2x - 1 being converted to vertex form. Form a perfect-square trinomial. y = x2
marishachu [46]

Solution: The needed answer for first blank is 1 and the needed a for second blank is 1.

Explanation:

The given equation is y=x^2+2x-1.

The form of perfect square is (x+y)^2=x^2+2xy+y^2.

The given equation can be written as y=(x^2+2x)-1.

To make the perfect square we can add or subtract (\frac{b}{2a})^2 in the given equation. Where, a is coefficient of x^2 and b is coefficient of x. In the parenthesis the coefficient of x^2 is 1 and coefficient of x is 2.

(\frac{b}{2a})^2=(\frac{2}{2(1)})^2=1

So, the given equation is written as y=(x^2+2x+1)-1-1

y=(x+1)^2-2

Therefore, the needed answer for first blank is 1 and the needed a for second blank is 1.

What is the probability of rolling two dice, and having a total of 8 dots showing? Express your answer as a percent
Scrat [10]
13.89%

The value of the first die can be any number except for 1 because even if the second die rolls a 6, the total will only be 7. This means that there is a 5/6 chance of rolling an appropriate number with the first die. The second die has a 1/6 chance of rolling any given number. Any given number can be added to only one of the five numbers from the previous die to equal an 8. As a result, both numbers must be multiplied.

5/6 x 1/6 = 5/36 or 13.89%
