final 100 point giveaway although quick favor if i give you 100 points can i get five brainliest also make sure you giveaway 100 points on here two thank you

The border line of the linear inequality 4x + 7y < 5 is dotted true or false?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.

Find the zeros of each function. f(x) = 6x^2 - 7x - 20
