3. if x and y are integers such that x2=64 and ys=64, which of the following could be true?
1. x = 8
ii. y = -4
iii. x +y = -4
a. i only
b. ll only
c. i and iii only
d. ii and iii only
c. land
and i only

1 is c

2 is a

3 is a

step-by-step explanation:

24

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

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
