Answer from: braydenmcd02

D. (2/3,1/5)

Step-by-step explanation:

To know which one belongs to the graph of 3x-5y = 1, we will evaluate the function with the options given

3x - 5y = 1

A. x = -2/3 y = -1/5

3(-2/3) - 5(-1/5) = 1

-2 - (-1) = 1

-2 + 1 = 1 wrong

B. x = -2/3 y = 1/5

3(-2/3) - 5(1/5) = 1

-2 - 1 = 1

-2 - 1 = 1 wrong

C. x = 2/3 y = -1/5

3(2/3) - 5(-1/5) = 1

2 - (-1) = 1

2 + 1 = 1 wrong

D. x = 2/3 y = 1/5

3(2/3) - 5(1/5) = 1

2 - 1 = 1

2 - 1 = 1 CORRECT

if we achieve equality it means that the point belongs to the graph

Answer from: expresslmnop

Step-by-step explanation:

We want to determine the solution to the equation, 3x-5y=1

We will check by substituting values of x and y into the left hand side of the equation and the values that satisfy the equation would be the solution.

1) substituting x = - 2/3 and y = -1/5 into the equation, it becomes

3 × -2/3 -5 × 1/5 = - 3

(-2/3, - 1/5) doesn't belong to the graph.

2)substituting x = - 2/3 and y = 1/5 into the equation, it becomes

3 × -2/3 -5 × -1/5 = - 3

(-2/3, 1/5) doesn't belong to the graph.

3) substituting x = 2/3 and y = - 1/5 into the equation, it becomes

3 × 2/3 -5 × -1/5 = 3

(2/3, -1/5) doesn't belong to the graph.

4) substituting x = 2/3 and y = 1/5 into the equation, it becomes

3 × -2/3 -5 × -1/5 = 1

(2/3, 1/5) belongs to the graph

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
