Answer:

  x ∈ (-∞, 9) U (-1, ∞)

Step-by-step explanation:

Get the absolute value by itself. Do that by multiplying by 4.

  |3x +15| > 12

This resolves to two cases:

<u>3x +15 > 12</u>

  x +5 > 4 . . . . divide by 3

  x > -1 . . . . . . .subtract 5

<u>-(3x +15) > 12</u>

  x +5 < -4 . . . . divide by -3

  x < -9 . . . . . . . subtract 5

Then the solution in interval notation is ...

  x ∈ (-∞, 9) U (-1, ∞)

a 28 inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third pi
klasskru [66]
Where x is the length of the first piece
x + 2x + 6x + 1 = 28 \\  \\ 9x = 27 \\  \\ x = 3
so the first piece is 3 inches, the second is 6 inches and the third is 19 inches

A camp counselor starts from home and drives to a campground. The expression 130−60t represents the distance, in miles, the coun
telo118 [61]

Answer:

<em>The value 60 represents the speed of the vehicle the counselor is driving.</em>

Step-by-step explanation:

<u>Linear Function</u>

The linear relationship between two variables d and t can be written in the form

d=mt+b

Where m is the slope (or rate of change of d with respect to t) and b is the y-intercept or the point where the graph of the line crosses the y-axis

The function provided in our problem is

d=130-60t

Where d is the distance in miles the counselor still needs to drive after t hours. Rearranging the expression:

d=-60t+130

Comparing with the general form of the line we can say m=-60, b=130. The value of -60 is the slope or the rate of change of d with respect to t. Since we are dealing with d as a function of time, that value represents the speed of the vehicle the counselor is driving. It's negative because the distance left to drive decreases as the time increases
