Without drawing the graph of the equation, determine how many points the parabola has in common with the x-axis and whether its vertex lies above, on, or below the x-axis. y=x2−12x+12 1 point in common; vertex on x-axis
2 points in common; vertex above x-axis
no points in common; vertex above x-axis
2 points in common; vertex below x-axis

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

i wish i could you, i have no idea how to answer this

step-by-step explanation:

7x7=4 so if u carry the 9 it will be 33
