Step-by-step explanation:
1000-1000= 0
0+1000=1000
The most helpful form to find the coordinates of the minimum is the vertex form.
<h3>Which form is better to find the minimum?</h3>
Remember that for a quadratic equation with a positive leading coefficient, the minimum is at the vertex.
So the better form to determinate the coordinates of the minimum value will be the vertex form, where if the vertex is (h, k), we get:
y = a*(x - h)^2 + k
In this case, the first option is in that form:
y = (x + 1)^2 - 25
so:
h = -1
k = -25
This means that the coordinates of the minimum are (-1, -25)

Answer:
The brother is 36 years old.
Step-by-step explanation:
b = brothers age
b - 18 = 18 | Given
b = 36 | Add 18 to both sides to cancel out -18 and get his age.
For the first die, the probability that the number is less than 3 is 2/6 or 1/3 because there are only 2 numbers (1 and 2) which are less than 3. For the second die, the probability that the number is greater than 4 is also 1/3 for only the numbers 5 and 6 satisfy the condition. To obtain the total probability, multiply the two probabilities because of the conjunction "and".
Thus, the answer is 1/9.
