Answer:
(1/2)(x³ - 3)
Step-by-step explanation:
That would be (1/2)(x³ - 3).
Step-by-step explanation:
x+2y = 10 ...1
-x+y = 2 ...2
...1 + ...2
x+2y+(-x+y) = 10 + 2
3y = 12
y = 12/3
= 4
Replace y = 4 in ...1
x + 2(4) = 10
x + 8 = 10
x = 10 - 8
= 2
(x,y) = (2,4)
Answer:
-19
Step-by-step explanation:
f(x) = -11 + 8x
f(-1) =-11 + 8(-1)
= -11 -8
= -19
Answer:
(x/4) +1 OR (4/x)+1
