you just gotta look at the angles, the middle letter is usually what's being focused on

17. angle QMR is less that TMS

18. angle QMR and angle TMS are supplementary angles

19. angle QMR and angle MTS are vertical angles

20. If measure angle QMT = 70 degrees, then measure angle RMS is 70 degrees because they are congruent

Which of the following values for x and y satisfy the following system of the equations?

weqwewe [10]

Answer:

The answer to your question is letter C

Step-by-step explanation:

Equations

x + 4y = 10

5x + 10y = 20

Process

1.- Substitute all the options in both equations and evaluate them

a) x = 3, y = 2 This option is incorrect

(3) + 4(2) = 10 3 + 8 = 10 11 ≠ 10

5(3) + 10(2) = 20 15 + 20 = 20 35 ≠ 20

b) x = 2, y = -3 This option is incorrect

(2) + 4(-3) = 10 2 -12 = 10 -10 ≠ 10

(2) + 10(-3) = 20 2 - 30 = 20 -28 ≠ 20

c) x = -2, y = 3 This is the right answer

(-2) + 4(3) = 10 -2 + 12 = 10 10 = 10

5(-2) + 10(3) = 20 -10 + 30 = 20 20 = 20

d) x = 3, y = -2 This option is incorrect

(3) + 4(-2) = 10 3 - 6 = 10 - 3 ≠ 10

5(3) + 10(-2) = 20 15 - 20 = 20 -10 ≠ 10

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.
