Solve each system using the substitution method. Show all work and steps. 4.5.1) 2x-5y=8
x=3y-1
A. Substitute the equation that is already solved for one variable into the other equation.

B. Solve for the single variable in the one-variable equation.

C. Substitute the result from the previous step into x=3y−1 and solve for the unknown variable.

D. Write the solution as an ordered pair. E. Check the solution with the equation not used in Step C.

Which shows the correct substitution of the values a, b and c from the equation 1=-2x+3x^2+1

The square root of 9x plus 7 plus the square rot of 2x equall to 7

Me max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
