What’s the answer please? ..

If 1 is divided by the sum of y& 4.the result is equal to 3 divided by 4, find the value of m

7.(03.01 lc)which set represents the range of the function shown? {(-1, 5), (2,8), (5, 3), 13, -4)} (5 points){-1, 2, 5, 13){(5, -1), (8, 2), (3,5), (-4, 13)){-4, 3, 5, 8}{-4, -1, 2, 3, 5, 5, 8, 13}

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