He function f(x) = x2 + 10x – 3 written in vertex form is f(x) = (x + 5)2 – 28. what are the coordinates of the vertex?

a.(–5, –28)
b.(–5, 28)
c.(5, –28)
d.(5, 28)

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
