What is the slope and equation of a line that is perpendicular to the y-axis and passes through the point (3,12) A . The slope is undefined and the equation of the line is y=12 .

B . The slope is zero and the equation of the line is x=3 .

C . The dlope is zero and the equation of the line is y=12 .

D . The slope is undefined and the equation of the line is x=3 .

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

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
