Line segment AB is reflected across the y–axis to form line segment CD. Then, line segment CD is rotated 90° clockwise about the
Maksim231197 [3]

Answer:

The coordinates of EF are E(5,-4) and F(1,-4).

The line segment EF is in QIV

Step-by-step explanation:

The line segment AB has vertices at: A(-4,5) and B(-4,1).

We apply the rule (x,y)\to (-x,y) to reflect AB in the y-axis to obtain CD.

\implies A(-4,5)\to C(4,5)

\implies B(-4,1)\to D(4,1)

We apply the rule (x,y)\to (y,-x) to rotate CD 90 degrees clockwise about the origin to obtain EF.

\implies C(4,5)\to E(5,-4)

\implies D(4,1)\to F(1,-4)

The coordinates of EF are E(5,-4) and F(1,-4).

The domain and range of a function is the set of input and output values, the function can take.

  • <em>The domain is [0,6]</em>
  • <em>The range is [0,90]</em>

<em />

From the question, we have:

\mathbf{Rate = \$15}

<u>The domain</u>

He cannot mow more than 6 yards a day.

This means that the domain is: 0 to 6

<em>This is properly represented as: [0,6]</em>

<u></u>

<u>The range</u>

When he mows 0 yards, his earnings is:

\mathbf{Earnings = 0 \times \$15 = \$ 0}

When he mows 6 yards, his earnings is:

\mathbf{Earnings = 6 \times \$15 = \$ 90}

This means that the range is: 0 to 90

<em>This is properly represented as: [0,90]</em>
