2x² + 3x -8 = 0
a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73
for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a
So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)
Hopefully helpfull.. ^_^
Least-squares regression is used to find the equation of best fit of a linear model
The equation of the least-squares regression line for predicting GPA from the number of absences is
The given parameters are:
The equation of the least-squares regression line is represented as:
Where:
So, we have:
Substitute values for a and b in
So, we have:
Approximate
Hence, the equation of the least-squares regression line for predicting GPA from the number of absences is

Answer:
12
Step-by-step explanation:
Answer:
area= 5/12
Step-by-step explanation:
Answer:
5c+4=2(c-5)
opening the parentheses we get:
5c+4=2c-10
putting like terms together we get
5c-2c=-10-4
3c=-14
c=-14/3
so the answer would be A. C = - 4 2/3
