I need to understand the solution.

Mathematics
1 answer:
Anika [276]3 years ago
4 0

Answer:

A

Step-by-step explanation:

Rules:

odd x odd = odd

even x even = even

even x odd = even

even + even = even

odd + odd = even

odd + even = odd

We can determine whether 2a + 3b is odd if we have both statements because we know that a is odd and 2 is even, which means their product will be even. 3 is odd and b is odd, so their product will be odd. The sum of the even and odd will be odd.

If we have just the second statement we can determine the answer because anything multiplied by 2 is even.

So whether or not we know if a is odd, we know that 2a is even because 2 doubles everything which means it's divisible by 2 which means it's even.

However, statement 1 alone is not enough because if a is odd, then 2a is even. However, 3b can be even or odd depending on b. If b is odd, then 3b is odd. if b is even, 3b is even.

Therefore, if you have statement 2 you can answer the question but if you only have statement 1 then you also need statement 2

A) The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over times, x measured in
Brums [2.3K]

From the given linear function, we have that:

A. The function is constant on the following interval: B.2 ≤ x ≤ 5.

B. The function is increasing on the following interval: A.0 ≤ x ≤ 2.

C. The function is decreasing the fastest on the following interval: D.5 ≤ x ≤ 6.

D. The justification for the previous item is: D.5 ≤ x ≤ 6 is the interval where the slope is the steepest.

<h3>When a function is constant?</h3>

A function is constant when it's graph is an horizontal line, hence in this problem the function is constant for two intervals.

  • 2 ≤ x ≤ 5.
  • 10 ≤ x ≤ ∞.

Hence, in item A, option B is correct.

<h3>When a function is increasing?</h3>

A function is increasing on the intervals that y is increasing while x increases, that is, the function is moving right and up.

Hence, in item B, option A is correct.

<h3>When a function is decreasing?</h3>

A function is decreasing on the intervals that y is decreasing while x increases, that is, the function is moving right and down.

The decrease is faster when the division of the change in the output by the change in the input has the lower value(greater absolute negative).

Hence:

  • In item 3, option D is correct.
  • In item 4, option D is correct.

Which of the following sets of numbers could be the lengths of the sides of a triangle?
kicyunya [14]

Answer is C. 8, 3, 6

To answer this, you must know the Triangle Inequality Theorem.

The two shortest sides when added together, must be greater than the longest side.

A. 2 + 4= 6 which can't work since it equals the longest side of 6

B. 4 +2=6 The sum would be less than 8, which doesn't work

C. 6 +3 = 9 the sum is greater than 8, which makes it a triangle

D. 3 +8 = 11 11 is less than 12
