1) Put the equation in quadratic form y=adº+bx+c. x2-y=-4x - 3
y=x2 - 4x -3
y=x2 – 3x +4
y= x2 + 4x +3
y= x2 + 4x - 3

step-by-step explanation:

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
