The fire department is having a BBQ fundraiser. The hot dogs costs $1.50 each and cans of soda cost $0.75 each. The department uses the algebraic expression 1.50x + 0.75y to calculate
customers’ total expenses.
a. What does the x variable represent?
b. What does the y variable represent?
c. A family buys 7 hot dogs and 4 sodas. What are their total expenses?

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
