I need help with this please. Can someone help me? If y=5 when x=-3, find x when y=-1
If y=25 when x=15, find y when x=6

5. x=0.6 or 3/5 (it's just the fraction and decimal form)

6. y=10

Step-by-step explanation:

5. We are given y=5 and x=-3, so whenever  and need to find x if y=-1

We need to find the "x" for the second proportion

Using this information we can create a ratio or proportion. To understand this better, (usingy=5 and x=-3) we can say that for every 5 of something (y) we have -3 of something (x). We can create a "key" using the proportionality:

here is our proportion

lets cross multiply first, 5x=-1(-3)  this simplifies to 5x=3, divide 5 from both sides, 5x/5=3/5  and you x=3/5, so this means that x is 3/5 or 0.6 as decimal

6. Lets set up our "key" again ,

our ratio is for every 25 something (y) we have 15 something(x) or 25/15 or 25:15

  this is our proportion, lets cross multiply to solve for "y"

25*6=15y this simplifies to 150=15y

lets divide both sides by 15, 150/15-15y/15  and we get our final answer

10=y so our why for this is 10
