Multiply the top equation by three to eliminate y.

3 (x - 3y = 1) -> 3x - 9y = 3
3x - 5y = 11

Subtract the two equations; X cancels out.

-4y = -8
y = 2

Plug y back into any of the equations to find x.

x - 3(2) = 1
x - 6 = 1
x = 7

Answer:

39

Step-by-step explanation:

134 + 167 = 301

301/7=43

301+430= 344

344/9 = 38.2  so you would need 39 tables

Which sum represents the partial fraction decomposition?​
Alex Ar [27]

It's the last option again. You have 1 linear factor (3<em>x</em>) and 2 copies of a quadratic factor (<em>x</em>² + 10), and the partial fractions with the quadratic factor need to have a linear polynomial in the numerator.

Able, Ben and Cal each played a game able's score was six times ben's score, Cale score was a hird time of Able's score write do
Svetradugi [14.3K]

Answer:

Abel to Ben: 6

Abel to Carl: 3

Ben to Carl: 0.5

Step-by-step explanation:

First we formulate the problem in equations:

Abel = 6 * Ben

Cale = Abel / 3

If Cale's score is Abel's score over 3, so Abel's score is 3 times Cale's score.

If Abel's score is 6 times Ben's score, and 3 times Cale's score, then Cale's score is 2 times Ben's score (so Ben's score is 0.5 times Cale's score)

So, the ratio between all scores are the following:

Abel to Ben: 6

Abel to Carl: 3

Ben to Carl: 0.5

Solve the inequality and graph on a number line.
Crazy boy [7]
So on the number line put a circle around the answer you got when you solved it!! And since the is a line under it you need to fill in the circle!!! So how do u know which way the line goes you ask???? So which ever way the inequality is pointing that is the way the lube goes!!! Just text me if you need a pic!!!!

Use DeMoivre's Theorem to find (3cis*pi/6)^3
Sonbull [250]

The correct value of (3cis(pi/6))³ is 27i.

<h3>What is Complex Number?</h3>

Complex numbers are numbers that consist of two parts — a real number and an imaginary number. Complex numbers are the building blocks of more intricate math, such as algebra.

Given the complex number in polar coordinate expressed as

z = r(cos∅+isin∅)

zⁿ =  {r(cos∅+isin∅)}ⁿ

According to DeMoivre’s Theorem;

zⁿ =  rⁿ(cosn∅+isinn∅)

Given the complex number;

(3cis(pi/6))³

= {3(cosπ/6 + isinπ/6)}³

Using  DeMoivre’s Theorem;

= 3³(cos3π/6 + isin3π/6)

=  3³(cosπ/2 + isinπ/2)

= 3³(0 + i(1))

= 27i

Thus, the correct value of (3cis(pi/6))³ is 27i.
