All the rational roots of the polynomial f(x) = 20x4 + x3 + 8x2 + x - 12 are 3/4 and -4/5.
Remember this! The equation that represents a proportional relationship, or a line, is y=kx, where k is the constant of proportionality.
She sold 36 White shirts. Its 48 shirts in total so it would be a ratio of 1/4. 1=Blue shirts and 4=total shirts sold. divide 48 by <span>¼.soyou get 12 shirts. the blue shirts of course.48-12 =36. Another way to check your work is 12 x 3 = 36.
