Given f(x) = x2 – 3 and g(x) =
x + 2
Find (gºf)(4).

15

Step-by-step explanation:

(gоf)(4) means g of f of 4. You would plug in f(4) into g(x).

f(4)=(4²)-3=16-3=13

Now that we know f(4) is 13, we would plug in 13 to g(x).

g(13)=13+2=15

step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
