A cereal company finds that the number of people who will buy one of its products in the first month that it is introduced is linearly related to the amount of money it spends on advertising. If it spends ​$30,000 on​ advertising, then​ 100,000 boxes of cereal will be​ sold, and if it spends ​$100,000 on​ advertising, then​ 200,000 boxes of cereal will be sold. (a)
Write an equation that relates the amount A spent on advertising to the number x of boxes the company aims to sell.
(b)
How much advertising is needed to sell 500,000 boxes of​ cereal?
(c)
Interpret the slope.

you can't solve x because it is 2 linear equation and you only have one equation

(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
