Y=-2x-7
Y=mx+b where m is the slope and b is the y-intercept
x - y = 14
given the ratio x : y = 5 : 3
then let x = 5x and y = 3x, hence equation can be expressed as
5x + 3x = 56
8x = 56 ( divide both sides by 8 )
x = 7
Hence x = 5 × 7 = 35 and y = 3 × 7 = 21
Thus x - y = 35 - 21 = 14

Step-by-step explanation:
185 is to 14.8 as x is to 18.5
185/14.8 = x/18.5
x = 185(18.5)/14.8
x = $231.25
You find the prime factorization by breaking the number down into other numbers that are prime. Start by breaking up 312 into 39 * 8. 39 breaks up into 3 * 13, and 8 breaks up into 4 * 2 which breaks up into 2 * 2. So the prime factorization of 312 is 3 * 13 * 2 * 2 * 2 or
. When you multiply those together you'll get 312.
