Answer & Step-by-step explanation:
n represents our number. So, twice a number would be 2n because twice means multiply by two.
When the problem says 6 less, then it means 6 less than 2n. So, it would look like 2n-6.
FInally, the problem says that all of this equals 17 so 17 would be the result.
So, you answer is 2n-6 = 17. This is answer choice B.
Answer:
b
Step-by-step explanation:
<span>Let time taken by Luke to cover the distance = x hours
Speed of Luke = 6 miles per hour
Therefore, Distance covered by Luke = 6x ------(1)
Speed of Micah = 4 miles per hour
Since Micah walked 2 miles before Luke started running, Luke started 1/2 an hour after Micah started.
Therefore time taken by Micah to cover the distance = x+1/2
Distance covered by Micah = 4(x + 1/2) -------(2)
Equating (1) and (2)
6x = 4(x+1/2)
6x = 4x +2
2x = 2
x= 1
Therefore Luke would take 1 hour to cover the distance covered by Micah.</span>
Answer:
Point (4,4) satisfies the required condition.
Step-by-step explanation:
x²-3x+2 = x²-2x-x+2
= x(x-2)-1(x-2)
= (x-2)(x-1)
According to the given information
y ≤ (x-2)(x-1) ...(1)
So lets consider one point having coordinates (4,4).
Substitute (4,4) in equation (1), we get
4≤ (4-2)(4-1)
4 ≤ 6
Hence point (4,4) satisfies the above condition. It's only one example there will be more points which satisfies the required condition.
