Two quantities, x and y, are directly proportional. If x is doubled, what happens to y?
vagabundo [1.1K]

Answer:

y is also doubled.

Step-by-step explanation:

Direct proportionality between x and y means that

y \propto x

or

y=cx,

which indicates a linear relationship between  x and y because they are related by a constant.

Therefore, if x is doubled, then the new value of y is y_{new}

y_{new}=c(2x)

y_{new}=2(cx)

y_{new}=2y

The new value of y is 2 times the previous; therefore, y is doubled as x is doubled.

Help with geometry!!!!!!!
Black_prince [1.1K]
Since the angle under angle 3 is a right angle (because of the little orange square) we can assume that angle 3 plus angle 2 equals 90 degrees. so 
(2x - 5) + (4x - 13) = 90
6x - 18 = 90
6x = 108
x = 18
measure of angle 2 = 36 - 5 = 31
measure of angle 3 = 72-13 = 59
