Decide whether each expression is equivalent to 0.75t-21. 3/4t-21 3/4( t-21) 0.75( t-28) t-0.25t-21. Explain how you know

only 10/60 isn't equivalent

hope this : )

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

okay..i will pick 8!
