Error analysis - describe the error in a sentence or two. then, solve the problem correctly.
13.
if f(x) = 2x - 1. then find the x-value so that f(x) = 21.

f(21) = 2(21-1
f(21) = 42-1
f(21) = 41

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

probability for j is 1/4

while

a is 1/6

the answer to this would be 5x^3-6x^2-24 over 3x^2

hope this if needed hmu
