Follow the directions to solve the system of equations by elimination. 8x + 7y = 39 4x – 14y = –68 multiply the first equation to enable the elimination of the y-term. add the equations to eliminate the y-terms. solve the new equation for the x-value. substitute the x-value back into either original equation to find the y-value. check the solution. the solution to the system of equations is

The graph shown below expresses a radical function that can be written in the form f(x)=a(x+k)1/n+c what does the graph tell you about the value of n in this function

The number of hours per week that the television is turned on is determined for each family in a sample. the mean of the data is 37 hours and the median is 33.2 hours. twenty-four of the families in the sample turned on the television for 22 hours or less for the week. the 13th percentile of the data is 22 hours. approximately how many families are in the sample? round your answer to the nearest integer.
