Step-by-step explanation:
Quadratic regression generally requires the use of "technology" to aid in finding the equation of the curve of best fit. Use the technology you've been introduced to.

When only a few data points are provided, I prefer to use the Desmos graphing calculator. It shows the equation to be ...
y = x^2 +10x -9
Answer:
21
Step-by-step explanation:
- AC = 64
- AB = 7x + 8
- BC = 3x + 6
<u>Since AC = AB + BC</u>
- 7x + 8 + 3x + 6 = 64
- 10x + 14 = 64
- 10x = 50
- x = 50/10
- x = 5
------------------
BC = 3x + 6 = 3*5 + 6 = 21
Answer:
Step-by-step explanation:
If 3⁄4 gallons of water come out of a hose in 15 minutes, to calculate the rate of water that comes out in an hour (60 minutes), we will use the expression;
3/4 gallons = 15 minutes
x gallons = 60minutes
cross multiply
15x = 3/4 * 60
15x = 180/4
15x = 45
x = 45/15
x = 3/1
x = 3:1
Hence the water rate in gallons per hour is 3 gallons per hour
