The formula f=5280m can be used to convert a measurement of f feet to an equivalent measurement m miles. if an airplane flies at 21,120 feet above the ground, how much is that in miles? a. 4 miles b. 5.3 miles c. 111, 513, 600 miles d. 132, 620, 600 miles

yes

step-by-step explanation:

yes

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

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
