Answer:

  M = 7x² +21

Step-by-step explanation:

Subtract the unwanted terms on the left from both sides.

  (-7x² +6x -16) + M = 6x +5

  M = 6x +5 -(-7x² +6x -16)

  M = 7x² +21 . . . . simplify

Can I please get help? Find M1 and M2
marishachu [46]

Answer:

m∠1 = 110° and m∠2 = 70°

Step-by-step explanation:

m∠1 = 110° since vertical angles

To find m∠2, m∠1 and m∠2 must add to 180°

m∠1 + m∠2 = 180°

110° + m∠2 = 180°

m∠2 = 70°

What are the values of a 1 and r of the geometric series? 1 3 9 27 81.
sp2606 [1]

For the given geometric series the value of the common ratio(r) is 3, while the value of a₁  is 1.

<h3>What is geometric series?</h3>

A series of numbers whose any two consecutive numbers are always in a common ratio of that series.

Given to us

Series,  1 3 9 27 81

To find the value of the common ratio(r), we will simply find the ratio of any two consecutive numbers, therefore,

r = ratio = \dfrac{3}{1} = 3

As we can see the common ratio of the given series is 3, therefore, every next number will be thrice the number before.

We need to find the value of a₁ for the given  series, and as we know that a₁ is the first number of the series with which the series is starting, therefore,

a₁  = 1

Hence, for the given geometric series the value of the common ratio(r) is 3, while the value of a₁  is 1.
