Answer:
D(t)=200-40*t
Step-by-step explanation:
He was already travelling for 3 hours, so he travelled 3*40=120miles. Total distance between his house and city A is 120+80=200miles. And he is travelling 40m/h. So I think this function represent his distance from city A depending how much time he was travelling (t).
D(t)=200-40*t
1 is a and 2 is b hope its right
3x+4=6+7x
Subtract 3x from both sides
4 = 6 + 4x
subtract 6 from both sides
-2 = 4x
Divide by 4 on both sides
-1/2 = x
Answer:
The value under the radical is 3
Step-by-step explanation:
9^(2/3) This means 9 squared then find find the cube root of the answer.
9^(2/3)=∛(9^2 )
= ∛81
= ∛(3×3×3×3) = ∛(3)³ ₓ ∛3
= 3∛3
The value under the radical is 3
I hope this now shows clearly the number under the radical is 3.
