Using data for the years 1985 to 1990, the function y = 9x + 10.8 can be used to estimate the first trend, while the function y = 5.5x + 30 can be used to estimate the second trend. For both functions,
x is the number of years since 1985. If these trends continue, in what year are the two trends
equal?

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

"a" determine whether sage found the correct quotient. show your work

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
