The points (4, 5), (−1, 7), (−2,−2), and (6.5,−10.5) reflected in the x-axis followed by the y-axis are (−4,−5), (1,−7), (2, 2),
Triss [41]

Reflecting the points in the y-axis followed by the x-axis gives the same result as x-axis followed by the y-axis

<h3>Transformation</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are<em> rotation, reflection, translation and dilation.</em>

If a point A(x, y) is reflected along the x axis, the new point is A'(x, -y). If a point A(x, y) is reflected along the y axis, the new point is A'(-x, y).

Given the points (4, 5), (−1, 7), (−2,−2), and (6.5,−10.5). If it is reflected along the y axis it gives (-4, 5), (1, 7), (2,−2), and (-6.5,−10.5). If it is then reflected along the x axis it gives (-4, -5), (1, -7), (2, 2), and (-6.5, 10.5).

Reflecting the points in the y-axis followed by the x-axis gives the same result as x-axis followed by the y-axis

Dan invests £1300 into his bank account.
alexandr402 [8]

Given parameters:

Principal  = £1300

Interest rate  = 5%

Duration  = 2yrs

Unknown:

Total amount of Dan's principal = ?

To solve this problem, we apply the equation below:

  Total investment worth  = Principal + interest

   Interest  = \frac{PRT}{100}

where P is the principal

          R is the rate

          T is the time

Now, input the parameters;

     Total investment worth  = £1300 + £ \frac{1300 x 5 x 2}{100}

                                             = £1300 + £130

                                             = £1430

The amount after two years is £1430

Evaluate the function f(x) =-x/2 -7x -2 find f(-9)
NeX [460]

Answer:

f(-9)=\frac{131}{2}

Step-by-step explanation:

In order to evaluate a function at a given x-value, plug in that value into the actual function

f(x)=-\frac{x}{2} -7x-2\\\\f(-9)=-\frac{9}{2} -7(-9)-2\\\\f(-9) = \frac{131}{2}
