I WILL MARK BRAINLIEST THERE ARE TWO QUESTIONS (QUADRATIC EQUATIONS) If a parabola contains x-intercepts at (-8, 0) and (2, 0) what is the equation for the axis of symmetry? x= *

If a parabola contains x-intercepts at (-10, 0) and (3, 0), what is the equation for the axis of symmetry? x=___ *

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18

Can someone me with these two circle theorem questions asap?
