Answer:
1.125
Step-by-step explanation:
the unit cost is how much it cost per wheel
dozen is 12
so 12 times 6 is 72
so then you do 81/72 to get your answer
and you are probably wondering how i got the divison from was because i'm supposed to divide to find a unit cost.
the 81 was the total for the 72 packages of toy wheels
The answer is 7. So you would do
2(3)2=12
4(3)=12
12-12=0
0+7
7
(y² - 3)(y⁴ - 6y² + 9)
y²(y⁴ - 6y² + 9) - 3(y⁴ - 6y² + 9)
y².y⁴ - y².6y² + y².9 -3.y⁴ - 3.(-6y²) -3.( 9)
y⁶ - 6y⁴ + 9y² - 3y⁴ + 18y² -27
y⁶ - 6y⁴- 3y⁴ + 9y² + 18y² - 27
y⁶ - 9y⁴ + 27y² - 27
I hope this helps.
Answer:
19) slope=2 y-intercept is 1 equation is y=2x+1
