Find the y-coordinate of the y-intercept of the polynomial function defined below. f(x) = (5x + 5)

If rt is greater than ba, which statement must be true ?

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.

What is the distance from zero if a quadratic function has a line of symmetry at x=-3 and a zero at 4
