A construction crew is lengthening a road. The road started with a length of 57 miles, and the crew is adding 4 miles to the roa

d each day. Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked. Write an equation relating L to D . Then use this equation to find the total length of the road after the crew has worked 31 days.

The equation you can use to relate L to D uses the information in the first part of the problem. First, if we just add 4 miles every day (ignoring the other piece), the length of the road would be 4 times the number of days, or L = 4D. But since we started with 57 miles built, we have to add that in order to get the total length, so the equation would be:

L = 4D + 57

You can use this question to find any value of L or D if you know one of them. According to the questoin, we know the crew worked 34 days (or D). So if you plug in 34 for D you'll get:

L = 4(34) + 57 ->
L = 136 + 57 ->
L = 193

Answer:

see explanation

Step-by-step explanation:

Given f(x) then f(x - 2) represents a horizontal translation of f(x) shifted 2 units to the right, thus

The marked points on f(x) → f(x - 2) are

(0, 0 ) → (2, 0 )

(2, 4 ) → (4, 4 )

(3, 9 ) → (5, 9 )

The first position can be taken by any of the 10 runners

Now, the second position can be taken by remaining 9 runners

What is the slope and y-Intercept of the equation 3(y – 2) + 6(x + 1) - 2 = 0?
Ne4ueva [31]

Answer:

  • A. Slope = -2, y-intercept = 2/3

Step-by-step explanation:

<u>Convert the given equation into slope-intercept form:</u>

  • 3(y - 2) + 6(x + 1) - 2 = 0
  • 3y - 6 + 6x + 6 - 2 = 0
  • 3y + 6x - 2 = 0
  • 3y = - 6x + 2
  • y = - 2x + 2/3

The slope is -2, the y-intercept is 2/3

Correct choice is A
