I have 500 points so thought I could give 100 free points

400

Step-by-step explanation:

we would subtract 100 (the amount being given) from 500 (the total amount of points) as shown below

500 - 100 = 400

we can fact check by adding the amount taken back to the new amount

400 + 100 = 500

SEE? ACADEMIC USE FOR FREE POINTS!! :D

(lol)

i cant see the graph

step-by-step explanation:

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
