"the science club went on a two-day field trip the first day of the members paid $70 for transportation plus $12 per ticket to the Planetarium. the second day they paid $90 for transportation plus $9 per ticket to the geology Museum. write an expression to represent the total cost in dollars for two days for the 'n' members of the club." "an expression that represents the total cost in dollars for the two days for the 'n' members of the club is given by "

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

the answer is (-4,-4)

hope this ! : d

answer: 323 is how many she has ☃☃⛄❄

step-by-step explanation:

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
