Laura runs a factory that makes stereo tuners. Each R80 takes 6 ounces of plastic and 4 ounces of metal.
Each D200 requires 3 ounces of plastic and 6 ounces of metal. The factory has 174 ounces of plastic, 252
ounces of metal available, with a maximum of 18 R80 that can be built each week. If each R80 generates
$10 in profit, and each D200 generates $1, how many of each of the stereo tuners should Laura have the
factory make each week to make the most profit?
R80:
D200:
Best profit:

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
