I think conjecture is the answer
Rufina [12.5K]3 years ago
3 0

Answer:

It's b.

Step-by-step explanation:

That would be a counterexample.

For example we might conjecture that all numbers of the form n^2 - n + 41 are prime numbers. This is false because of the counterexample if n = 41 then 41^2 - 41 + 41 is divisible by 41.

How can 1/6x − 5 = 1/5x + 2 be set up as a system of equations?
Travka [436]
<span>Given equation = 1/6x – 5 = 1/5x + 2
how can it be set up as linear of equation?
let’s start solving the given equation to show the system of equations:
=> 1/6 x – 5 = y
=> 6y = x – 30
=> 6y – x = -30

=> 1/5 x + 2 = y
=> 5y = x + 10
=> 5y – x = 10

Thus, the system of equation of the given equations are:
=> 6y – x = -30</span><span>
=> 5y – x = 10</span>

Using the sum of the angle measures of a triangle, m angleC=?
Vedmedyk [2.9K]

Answer:

m∠C = 66°

Step-by-step explanation:

Given

m∠ A = 33°

m∠ B = 81°

To determine

m∠C = ?

We know that sum of angles of a triangle is 180°.

so using the equation

m∠ A + m∠ B +  m∠C = 180°

substituting m∠ A = 33°, and m∠ B = 81° in the equatio

33° + 81°+m∠C= 180°

114° + m∠C = 180°

m∠C = 180° - 114°

m∠C = 66°

Therefore,

  • m∠C = 66°
