Grade eight math studying for exams . i have been trying to solve this for hours and am not able to. i only use one variable equations. none of my friends can explain it either. you so much! 25 points and brainliest!

Which facts are true for the graph of the function below? check all that apply. f(x) = log8 x. (30 points pls )

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.
