Answer:
Step-by-step explanation:
4x= 4(-1)= -4
3y= 3(2)=6
4x^3y= -4^6
=4096
4096^2= 16777216
(f-g)(x) = f(x) - g(x)
= (x^3 -2x+6) - (2x^3+3x^2-4x+2)
= x^3 -2x +6 -2x^3 -3x^2 +4x -2 . . . . distribute the negative sign
= (1-2)x^3 -3x^2 +(-2+4)x +(6-2) . . . . . combine like terms
(f-g)(x) = -x^3 -3x^2 +2x +4
Answer:
Logan's average is 2,250 meters per hour
Step-by-step explanation:
60 ÷ 1/3 = 20
1/3 of an hour is 20 min
Logan swam 750 meters in 20 minutes
20min × 3 = 60min = 1 hour
750 meters × 3 = 2250
Logan's average is 2,250 meters per hour
Answer:
x = 5
Step-by-step explanation:
To find the value of x make sure to get it on one side
First subtract 3x from each side. This makes the equation now
3x + 2 = -8 + 25
Now see what 25 subtract by 8 is (17)
3x + 2 = 17
Next subtract 2 from both sides
3x = 15
Lastly, divide 15 by 3, making x equal 5
x = 5
Answer:
x=12
Step-by-step explanation:
x-9=3
basically 3 + 9=12 so 12-9=3
