Answer:

- 145

Step-by-step explanation:

Evaluate g(3) then use the value obtained to evaluate f(x), that is

g(3) = - 2(3) + 1 = - 6 + 1 = - 5 , then

f(- 5) = (- 5)³ + 4(- 5) = - 125 - 20 = - 145

Ralph and Jody go to the store to buy chips and candy bars. Ralph buys 3 bags of potato chips and 4 candy bars for 375 cents. Jo
s2008m [1.1K]
3x+4y = 375
6x+ 4y= 600
-------------------
6x-3x  = 600 - 375

3x=225
x=225:3
x=75 cents

3*x+4y= 375
3*75+4y=375
225 +4y = 375
4y=375-225
4y=150
y=150:4
y=37,5 cents

the price is 75+37,5=112,5 cents for one bag of potato chips and one candy bar
