Step-by-step explanation:

If these coordinates reflected over y = -1, the resulting coordinate will be:

P = (-4, -6)

Q = (-2,-8)

R = (1, -4)

A reflected coordinates are mirror images of each other. From the given diagram, the coordinate points are;

P = (-4, -3)

Q = (-2,-4)

R = (1, -2)

If these coordinates reflected over y = -1, the resulting coordinate will be:

Check the picture below.

The complete question is

"Which values of x and y would make the following expression represent a real number? (4 + 5i)(x + yi)"

The value of x and y are all points that satisfy the equation would be,(4,-5).

Use the distributive property to simplify the expression.

The given expression is,

(4 + 5i)(x + yi)

4(x + yi)+ 5i (x + yi)

4x + 4yi + 5xi + 5yi^2

We know that i^2 = -1

4x + 4yi + 5xi - 5y

(4x - 5y) +i (  4y + 5x)

In x+iy, x is the real part and y is the imaginary part.

If the given expression represents a real number it means the imaginary part must be zero.

4y + 5x= 0

All the points which satisfy the above equation are the values of x and y for which the given expression is a real number.

For eg. (4,-5)

4y + 5x

4(-5) + 5(4)

= 0

LHS=RHS, which means the point satisfies the equation and the value of x and y are (4,-5).

The formula in factored form is (t - 3)(t - 9) and the swimmer dives into the water 3 seconds after the timer was started also, the swimmer comes back up 9 seconds after the timer was started.

Analysis:

at h(t) = 0 that is when the diver has not dived or at height 0 foot

the equation becomes [tex]t^{2}[/tex] -12t + 27 = 0

by factorizing,

[tex]t^{2}[/tex] -9t -3t + 27 = 0

(t-9)(t-3) = 0, this is the equation in factored form.

t = 3 or 9

These are the times, the height h(t) = 0

Which means the swimmer dived 3 seconds later or got to the top of water after 9 seconds in which case h(t) = 0

In conclusion, the swimmer dives 3 seconds later after the timer was started and the swimmer comes back up after 9 seconds are the true statements for this problem.

9.2 units

Step-by-step explanation:

A(-2,-2) and B(4,4) then the length is given by the distance formula

length = [tex]\sqrt{(4-(-2))^{2}+(4-(-3))^{2} }[/tex] units

           = [tex]\sqrt{6^{2}+7^{2} }[/tex] units

           = [tex]\sqrt{85\\[/tex] units

           = 9.2 units          

Answer:

AB ≈ 9.2 units

Step-by-step explanation:

calculate the length using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A (- 2, - 3 ) and (x₂, y₂ ) = B (4, 4 )

AB = [tex]\sqrt{(4-(-2))^2+(4-(-3))^2}[/tex]

     = [tex]\sqrt{(4+2)^2+(4+3)^2}[/tex]

     = [tex]\sqrt{6^2+7^2}[/tex]

     = [tex]\sqrt{36+49}[/tex]

     = [tex]\sqrt{85}[/tex]

     ≈ 9.2 units ( to the nearest tenth )

A parallel line has the same slope as the original line. So in this case the slope of the line is also 3/4. Now how do we know if it intersects the point? We need to adjust the y intercept.



Currently, we know the equation of the line is y= 3/4 x + b, where b is the thing we are looking for. We also have a point, which supplies the x and y. Plug that in and solve for b

-2 = (3/4)*(12) + b

You'll get b= -11

So the equation of the parallel line intersecting the point given is y= 3/4x -11.

I am assuming that the slope is 3/4 based on the way you formatted the original equation, but it's the same steps if the slope is different.
