Find the missing coordinate if the ordered pair is to be a solution to the equation 3x + y = 9

You are given only one equation, but are to find the values of two variables (x and y).  No soap.

However, you could arbitrarily let x=1 and then find the corresponding y value.

Then 3(1) + y = 9, so y = 6.  One point on this line is (1,6).  But there are an infinite number of other solutions.

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 )
