Answer 2
Answer:

Answer:

Step-by-step explanation:

Setting f(x) = -(x + 3)(x + 1) = 0 leads to identifying two roots/solutions of this equation:  x = -3 and x = -1.  The axis of symmetry is a vertical line halfway between these two roots:  x = -2.  This x = -2 is also the x-coordinate of the vertex.  Evaluating f(x) = -(x + 3)(x + 1) at x = -2 gives us the y-coordinate of the vertex:  y = -(-2 + 3)(-2 + 1) = -(1)(-1) = 1.

In summary, the vertex is at (-2, 1) and the two x-intercepts are (-3, 0) and (-1, 0).  The y-intercept is found by  setting x = 0 and finding y:  

f(0) = -(0 + 3)(0 + 1) = -3, or (0, -3)

Next time, please share the answer choices.  Thank you.

A die is loaded so that the number 6 comes up three times as often as any other number. what is the probability of rolling a 1 or a 6?

Answers

The probability of rolling a value of 1 or 6 for the unfair die ls 1/2

The probability of an event is given as :

P(event) = Required outcome / Total possible outcomes

Let the probability of other numbers on the die = n

Therefore, Probability of 6 = 3n

The Cummulative probability can be expressed thus since the Cummulative sun must be equal to 1 :

Other values on the die are 5 ; 1, 2, 3, 4, and 5

5n + 3n = 1

8n = 1

n = 1/8

The probability of other numbers = 1/8

Probability of 6 = 3(1/8) = 3/8

Probability of (1 or 6) = P(1) + P(6) = 1/8 + 3/8 = 4/8 = 1/2

Therefore, the probability of obtaining 1 or 6 is 0.5

Answer:

1/2.

Step-by-step explanation:

Probability totals must add up to 1.

P = probability.

If P(any number other than 6) = x,  then P(6) = 3x, so

3x + 5x = 1

x = 1/8

P(6) = 3/8 and P(not 6) = 1/8

Therefore P(6 or 1) = 3/8 + 1/8 = 1/2 (answer).


What is 6/10 plus 3/100

Answers

decimal form: 0.63
fraction form: (63)/(100)

Answer:

decimal form: 0.63

fraction form:  \frac{63}{100}

Step-by-step explanation:

3 goes after 6 and 100 replaces 10. For the decimal form you divide 63 by 100, which results in 0.63.

Richie is solving the equation x^2 – 12x = 28 by completing the square. What number should he add toboth sides of the equation to complete the square? Pleaseee Help

Answers

Answer:

Richie should add the number 36 to both sides.

Step-by-step explanation:

To complete the square, you need to divide b by 2, square it, then add it to both sides. In this case, you'd do this:

Convert 879/112 to whole or mixed number

Answers

\sf{ (879)/(112) =?}

\sf{ 112 * 7 = 784}

\sf{ 879 -784= 95}

\sf{ (879)/(112) =  (784+95)/(112) = (784)/(112) +  (95)/(112) = 7 +  (95)/(112) = 7 (95)/(112)}

\sf(879)/(112) = \boxed{7  (95)/(112)}
I don't know what you mean by "or" but I will do either one of them


879/112 to mixed number =

879 ÷ 112

= 7 R95

= 7 95/112


The denominator remains the same, the numerator is the remainder. While 7 is the whole number! :D
