Distribute:
= 4x ( x^3) + (4x)(-6) + (-7) (x^3) + (-7) (-6)
= 4x^4 + -24x + -7x^3 + 42
= 4x^4 - 7x^3 - 24x + 42
Good luck :)
Y= 2/3x + b
12= 2/3(9) + b
12= 6 + b
6 =b
Anwer: y= 2/3x + 6
Answer:
Expression: $7.50x + 15.50 = y Total Cost: $30.50
Step-by-step explanation:
x goes next to 7.50 because it is 7.50 per person, which makes it a variable that varies and can change.
since the expression is $7.50x + 15.50 = y, we just plug x in for 2 because he and his friend are going which is 2 people.
7.50(2) + 15.50 = 30.50
