Tickets to a baseball game cost $3 for a child’s ticket and $5 for an adult ticket. at the last game, $521 was collected when 139 people attended the game. which value could replace x in the table so that a single-variable equation can be written and solved to determine the number of child’s tickets, c, sold? 139 521 139 – c 521 – c

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

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)
