Answer:

1)   (6,2) (9,2) (3,8) (3,5)

2)   (2,-5) (5,-5) (-1,-11) (-1,-8)

Step-by-step explanation:

For the first question, your reflecting over the x-axis into quadrant I, so you just need to make all the coordinates positive.  The numbers stay the same - you just get rid of the negative signs.  (6,2) (9,2) (3,8) (3,5)

For the second problem, you subtract 4 from the x-value, and 3 from the y-value.

(6,-2) becomes (2,-5)

(9,-2) becomes (5,-5)

(3,-8) becomes (-1,-11)

(3,-5)  becomes (-1,-8)

What is the answer for 4i over 3+7i
icang [17]

Answer:

see explanation

Step-by-step explanation:

given \frac{4i}{3+7i}

To rationalise multiply the numerator/denominator by the conjugate of the denominator

the conjugate of 3 + 7i is 3 - 7i, hence

\frac{4i(3-7i)}{(3+7i)(3-7i)}

distribute the numerator/denominator

= \frac{12i-28i^2}{9-49i^2}

[ note that i² = - 1 ]

= \frac{12i+28}{9+49}

= \frac{28+12i}{58}

= \frac{28}{58} + \frac{12}{58} i

= \frac{14}{29} + \frac{6}{29} i ← in standard form

Extra points!!no links tho
Naddik [55]

Answer:

<h3>              a. the  vertex represents a minimum point</h3><h3>              b.  f(x) = (x + 5)² - 5</h3>

Step-by-step explanation:

a.

a = 1 > 0  ← that means the parabola opens up, so the vertex is minimum of the function

b.

  f(x)=x^2+10x+20\\\\f(x)=\underline{x^2+10x+25} - 25+20\\\\f(x)=(x+5)^2-5
