PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!! For which intervals - 1

Answers

Answer 1
Answer:

Answer:  B. ( -∞ , 0)   and   C. (1, 2)

Step-by-step explanation:

The y-value is increasing between x = -∞ and x = 0.

The y-value is decreasing between x = 0 and x = 1.

The y-value is increasing between x = 1 and x = 2.

The y-value is decreasing between x = 2 and x = +∞


So, the y-value is increasing at ( -∞ , 0) ∪ (1, 2)

What is the median of 37, 39,40, 42,42, 45, 48, 49, 51, 52?

Answers

To find a median, first order the numbers from least to greatest, or vice versa.
Then, the middle number in that sorted list is the median.

But, this list is already sorted.
So, the median is 42 & 45.

Technically, the answer is 42 & 45.

The middle of 42 & 45, however, is 43.5

Hope this helped!

HELP ME PLEASE!!!!!!!!!!!!!!!!!!!!Which of these shows the result of using the first equation to substitute for y in the second equation, then combining like terms? y = 2x 2x + 3y = 16
A. 8x = 16
B. 4x = 16
C. 5x = 16
D. 5y = 16

Answers

I got (A)
This is my answer

Final answer:

By substituting y = 2x into the second equation and combining like terms, we get the equation 8x = 16.

Explanation:

This question is from the field of Algebra. You are asked to substitute the first equation into the second equation, then simplify by combining like terms. Substituting y = 2x from the first equation into the second equation 2x + 3y = 16, we replace y with 2x, thus transforming the second equation into 2x + 3(2x) = 16. Distributing the 3 to the 2x within the parentheses gives us 2x + 6x = 16. By combining the like terms on the left side, we get 8x = 16 which is option A.

The second term of an arithmetic sequence is -39. The rule a, = a -1 + 12 can be used to find the next term of thesequence. What is the explicit rule for the arithmetic sequence?
a, = -51+12(n-1)
O a = -39+12(n-1)
O a, = 12+(-39)(n-1)
O a = 12+(-51)(n-1)

Answers

Answer:

A. an = -51+12(n-1)

Step-by-step explanation:

edge quiz

The solution is, the explicit rule for the arithmetic sequence is

a n = -51 + ( n - 1 ) · 12 .

What is Arithmetic progression?

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

The nth term of AP : a_n = a + (n – 1) × d

here, we have,

given that,

a 2 = -39

a 2 = a 1 + 12

- 39 = a 1 + 12

a 1 = - 39 - 12

a 1 = - 51 ( first term )

The common difference is : d = 12

The explicit rule for the arithmetic sequence:

a n = a1 + ( n - 1 ) d

a n = -51 + ( n - 1 ) · 12

Hence, The solution is, the explicit rule for the arithmetic sequence is

a n = -51 + ( n - 1 ) · 12 .
