Answer:
He is not correct. Even though 12 is higher than9 it is in the negative, meaning that on a number line it is going left.
If the 12 was positive, it would be warmer, but since its in the negative like the 9 he is incorrect and, in fact, it is colder.
Step-by-step explanation:
Answer:
so i dont know the answer but i know that if u are determining the surface are then u should multiply two times and then divide once
Step-by-step explanation:
so 10 times 8 times 8 =640

Answer:
D; 330, 5pi/3, 7pi/6, 2pi/3, pi/2
Step-by-step explanation:
Answer:
D. f(x) = 2x - 8
Step-by-step explanation:
What you do is you take the x number and but it into the x spot.
f(x) = 2x Put 5 into the x
2(5) = 10 does not equal 2.
f(x) = x -3 Put 5 into the x
5 - 3 = 2, but if you plug a different x into it, it doesn't work.
D. f(x) = 2x - 8 is your answer.
