Answer:
y=3x+20
Step-by-step explanation:
So first, I don't like fractions so I would multiply the whole equation by 4. This will make the equation 3x+y=20. Then you have to isolate the y to find the answer so you should subtract 3x from both sides. This will make the equation look like this y=-3x+20. Therefore, y=3x+20

Answer:
y = ±√(x − 16)
Step-by-step explanation:
y = x² + 16
To find the inverse, switch x and y, then solve for y.
x = y² + 16
x − 16 = y²
y = ±√(x − 16)
Explanation:
Any situation in which 40 items are divided into 8 or 5 divisions will be modeled by an equation of this sort. A couple of possibilities are ...
- "There are 40 in all, and 8 in each group. How many groups are there?"
- "There are 40 in all, divided into 8 groups. How many are in each group?"
__
The "items" could be any sort of units of measure: beads, people, tickets, feet, yards, square miles, cubic millimeters, stars in the sky, whatever. The idea is that grouping by 8 or 5 gives you 5 or 8 groups, respectively.
