The expression 2y+ 2.6 is equal to ? for y=5

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

As voters exit the polls, you ask a representative random sample of voters if they voted for a proposition. if the true percentage of voters who vote for the proposition is 63%, what is the probability that, in your sample, exactly 5 do not voted for the proposition before 2 voted for the proposition? the probability is
