Answer:
estimated gpa: 2.85
Step-by-step explanation:
Evaluate y=0.14x+0.75 at x = 15 (hours):
y = 0.14(15 hours) + 0.75
= 2.1 + 0.75
y = 2.85 = estimated gpa corresponding to 15 houirs of study
Cos(x) = adj/hyp
=3/5
A
thats it
the first number in slope intercept is the slope and the second number is the y-intercept
