Harold can buy 2 pounds of bananas for $7. Write an equation to represent the cost, c , for b bananas.

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

Ineed with this problem 21 show steps

Let u = {q, r, s, t, u, v, w, x, y, z} a = {q, s, u, w, y} b = {q, s, y, z} c = {v, w, x, y, z}. list the elements in the set.a ∩ (b ∪ c)a) {q, s, w, y}b) {q, y, z}c) {q, s, u, w, y, z}d) {q, r, w, y, z}
