What's a standard formula y=ax squared +bx+c with x=4 and othe x=7

Step-by-step explanation:

To find the x-intercept let y = 0 and solve for x. You can solve for x by factoring, completing the square, or using the quadratic formula. In this case, we end up with the square root of a negative number, so there are no x-intercepts. Step 4: Graph the parabola using the points found in steps 1 – 3.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
