Answer:

See below

Step-by-step explanation:

<h3>Given function </h3>
  • f(x) = 5x - 7

<u>Another notation for same function is</u>

  • y = 5x - 7, where 5 is the slope and -7 is the y-intercept
<h3>Questions </h3>

<u>1. Is the function increasing or decreasing? </u>

  • Increasing as x has positive slope

<u>2. What is the y-intercept? </u>

  • y- intercept is -7

<u>3. What is the slope? </u>

  • The slope is 5

<u>4. What is f(-2)? </u>

  • f(-2) = 5(-2) - 7 = - 10 - 7 = -17

<u>5. If f(x) = 0, what is x?</u>

  • f(x) = 0
  • 0 = 5x - 7
  • 5x = 7
  • x = 7/5
  • x = 1.4

Answer:

  1. It is increasing x has a positive slope as seen in the graph above
  2. y intercept is= - 7

<u>Solving</u><u> </u><u>s</u><u>tep</u>

f(x) = 5x - 7

Substitute x=0

f(0) = 5 \times 0 - 7

Calculate the product

f(0) = (0) - 7

When adding or Subtracting 0 the quantity does not change

f(0) =  - 7

  1. G
  2. Slope is =5 ⚄
  3. ?

f(x) = 0

0 = 5x - 7

5x = 0

x =  \frac{7}{5}

OR

x = 1.4

On a coordinate plane, quadrilateral Q R S T has points (0, 2), (negative 4, 0), (0, negative 3), and (4, 0).
Afina-wow [57]

By applying the definitions of <em>rigid</em> transformation ((x, y) → (0.5 · x, 0.5 · y)) and dilation, we conclude that the coordinates of Q'(x, y) are (0.1).

<h3>How to apply rigid transformations on a point</h3>

Herein we must apply a rigid transformation into a given point to determine an image. <em>Rigid</em> transformations are transformations applied on a <em>geometric</em> locus such that <em>Euclidean</em> distance is conserved. Dilations are a kind of <em>rigid</em> transformations such that:

(x, y) → (k · x, k · y), for k > 0

If we know that Q(x, y) = (0, 2) and k = 0.5, then the coordinates of Q' are:

Q'(x, y) = (0.5 · 0, 0.5 · 2)

Q'(x, y) = (0, 1)

By applying the definitions of <em>rigid</em> transformation ((x, y) → (0.5 · x, 0.5 · y)) and dilation, we conclude that the coordinates of Q'(x, y) are (0.1).
