Simplify 9 + 7 + n.
o n + 17
o d + 16
o 160

it’s supposed to be -4+45=41

step-by-step explanation:

m∠a is 90°

m∠b is 40°

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
