Solve each system of equations using the elimination method. check the solution. 5. 6 = 4x + 2y -19 = 4x - 3y 6. 4x - y = -2 2x + y = 2 7. 3x + 8y = 2 4x - 2y = -10 8. 2x - 4y = 10 -4x + 3y = -20

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form. −three fourthsx + y = 10 3x − 4y = −40 y = three fourthsx + 12 y = three fourthsx + 10
