What happens when a rational number is added to an irrational number

Mathematics
1 answer:
Whitepunk [10]3 years ago
6 0

The answer to your question is,

Each time they assume the sum is rational; however, upon rearranging the terms of their equation, they get a contradiction (that an irrational number is equal to a rational number). Since the assumption that the sum of a rational and irrational number is rational leads to a contradiction, the sum must be irrational.

HELP ASAP PLZ &amp;THANK YOU :)

The standard form:

Ax+By=C

The slope-intercept form:

y=mx+b

m - slope

m=\dfrac{y_2-y_1}{x_2-x_1}

b - y-intercept (0, b).

We have the point (0, 43) → b= 43.

Next point (2, 55). Substitute to the slope formula:

m=\dfrac{55-43}{2-0}=\dfrac{12}{2}=6

Therefore we have:

y=6x+43      <em>subtract 6x from both sides</em>

\boxed{-6x+y=43}

The sum of three consecutive whole numbers is 183 find the numbers
sergiy2304 [10]

Answer:

let the no.s be : x, x+1, x+2

then,

=> x + x+1 + x+2 = 183

=> 3x + 3 = 183

=> 3x     = 183 - 3

=> x  =  180/3

=> x = 60

therefore,  the whole no.s are 60, 61, and 62

Which is a valid prediction about the continuous function f(x)?
Bumek [7]
Without seeing the graph, it's impossible to tell. The same can be said if we don't know the function rule. However, we can rule out three non-answers. 

Choice B is false because the interval [1,3] has f(x) below zero but the rest of the interval to the right of x = 3 has f(x) not below zero.

Choice C is false. The value x = -1 leads to f(x) = 0 which is not greater than 0

Choice D is false because the values 8 and 4 are positive

After eliminating B, C, & D, we are left with choice A as the answer.
