Answer:
The value of y is 89.55 at x=15 and 60.69 at x=9.
Step-by-step explanation:
The equation of best fit line is

where, y is scores of two students after x working hours.
We need to find the score after 15 and 9 hours.
Substitute x=15 in the given equation.


Substitute x=9 in the given equation.


Therefore, the value of y is 89.55 at x=15 and 60.69 at x=9.
Answer: No
Step-by-step explanation:
If we don't know if the lines are parallel, we cannot conclude the angles are equal.

Yay I got easy points thank you bro
Step-by-step explanation:
Answer:
See explanations below
Step-by-step explanation:
Given the functions f(x)=2x+3 and g(x)=x^2-1
a. Find f(g(x))
f(g(x)) = f(x^2-1)
f(g(x)) = 2(x^2-1)+3
f(g(x))= 2x^2-2+3
f(g(x)) = 2x^2+1
Hence the composite function f(g(x)) is 2x^2+1
b) g(f(x)) = g(2x+3)
g(f(x) = (2x+3)^2-1
g(f(x)) = 4x^2+12x+9-1
g(f(x)) = 4x^2+12x+8
