Answer:
y = 160 - x
Step-by-step explanation:
Given :
Maximum text character = 160
x = number of typed characters
y = Number of characters left or unused characters
Unused characters = 160 at the start of a fresh message page, which reduced as characters are being typed.
Hence,
Unused characters = (maximum characters - number of typed characters)
y = 160 - x
Well, notice, we can pretty much see the x-intercepts if we set f(x) = 0, clearly they're just 6 and -2,
now, this is a quadratic equation, since it only has 2 solutions at most, recall your fundamental theorem of algebra.
so, the vertex will be right in middle of those two x-intercepts.
what's between -2 and 6?, well is +2 or just 2, so
x = 2.
so we know the x-coordinate for the vertex is the halfway point of 2, what's the y-coordinate?
f(x) = y = (
2 - 6)(
2 + 2)
y = ( - 4)( 4 )
y = -16thus the vertex is at, well you already know.

You're clicking at it. lol
Step-by-step explanation:
8:1 is same as 8 divided by 1 which is 8 and just divide 120 by 8 and you have 15 chaperones.:)
