a) The point-slope form of the equation of a line through point (h, k) with slope m is
  y - k = m(x - h)

In point-slope form, the equation of the line through (-3, -7) with slope -6/5 is
  y + 7 = (-6/5)(x + 3)


b) The graph of
  y = |x|-4
represents a translation downward 4 units of the graph of
  y = |x|
It retains the same general shape and axis of symmetry, but will have two (2) x-intercepts instead of one (1).

Evaluate the piecewise function for the given values.
adoni [48]

Answer:

f(-3) = -2

f(-2.6) = -2

f(0.6) = 2.4

f(4.5) = 8.5

Step-by-step explanation:

(Whole question:

Evaluate the piecewise function for the given values.

Find f(-3), f(-2,6), f(0.6), and f(4.5) for f(x)={ -2 If x ≤ 0 4x. If 0 <x <1. x + 4. If x ≥ 1)

As the piecewise function shows, the function f(x) has the value of -2 for values of x lesser or equal than 0, has the value of 4x if the value of x is between 0 and 1, and has the value of x+4 for values of x greater or equal than 1.

So, for f(-3), the value of x is lesser than 0, so we have that f(-3) = -2

For f(-2.6), the value of x is lesser than 0, so we have that f(-3) = -2

For f(0.6), the value of x is between 0 and 1, so we have that f(0.6) = 4*0.6 = 2.4

For f(4.5), the value of x is greater than 1, so we have that f(4.5) = 4.5 + 4 = 8.5

Answer:

  8

Step-by-step explanation:

You are given the hypotenuse and one leg of a right triangle, and are being asked to find the other leg. The Pythagorean theorem applies.

  TW² + TY² = WY²

  TW² = 17² - 15² = 64

  TW = √64

  TW = 8
