Answer: 125 ft cubed
Step-by-step explanation:
You add the equations together making sure one of the variables disappears by making one negative and one positive. In this situation y would alrady disappear 8x+y=-16
Answer:
x^4 -x^3 -4x^2-3
Step-by-step explanation:
f(x)=x^4−x^2+9
g(x)=x^3+3x^2+12
(f−g)(x)= x^4−x^2+9 - (x^3+3x^2+12)
Distribute the minus sign
(f−g)(x)= x^4−x^2+9 - x^3-3x^2-12
I like to line them up vertically
x^4 −x^2+9
- x^3 -3x^2-12
---------------------------
x^4 -x^3 -4x^2-3
Answer:

hope this helps :)
if it does, can I get brainliest, please??!
Answer: 9/23
Step-by-step explanation:
1- Convert the mixed fraction to an improper fraction. 9 x 2 + 5 = 23 and keep the original denominator. 23/9
2- Now “flip” the fraction to its reciprocal. 23/9 becomes 9/23
3- Check to see if it can be reduced. It cannot so there’s your answer. 9/23
