PLEASE HELP ME YALL I dont know this and its already late its my next period please

Steps to solve:

f(x) = 6(1 - x) when x = -8

~Substitute

f(-8) = 6(1 - (-8))

~Simplify

f(-8) = 6(1 + 8)

~Add in parenthesis

f(-8) = 6(9)

~Multiply

f(-8) = 54

Best of Luck!

step-by-step explanation:

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
