The complex conjugate of <span>7i</span><span> is </span><span>−7i </span>The complex conjugate of a number 

z is a number with opposite imaginary part.

So if <span>z=a+bi</span> then conjugate is: <span><span>¯z</span>=a−bi</span> for any <span>a,b∈R</span>

We can note, that if we represent all complex numbers in coordinate system, then for any number: the number z and its conjugate <span>¯z</span> are symetrical according to "real part" axis.

Ski Mountain sells lift tickets. Ski Mountain Sale Packages Number of Lift Tickets Total Cost Package A 3 $30 Package B 5 $60 Pa
LenaWriter [7]

Answer:

Packages A and C

Step-by-step explanation:

To find the ratio between the number of lifts to the cost we first remove the $ symbol and find out how much 1 lift will cost per package.

Package A =  3 : 30

Package B = 5 : 60

Package C = 12 : 120

Package D = 16 : 120

Now let's break it down.

Package A = 30/3 = $10 per lift

Package B = 60/5 = $12 per lift

Package C = 120/12 = $10 per lift

Package D = 120/16 = 7.5 per lift

So now we are able to know which packages have the same ratio.

Package A and C cost $10 per lift.

Answer:

(d) y≥-5

Step-by-step explanation:

first, we find the equation for the blue line:

a doesn't work as it goes diagonally, so as b, e, or f.

so it must be y≥-5 or y<-5

since the graph is shaded above the line, it must be greater than or greater than or equal to, so it must be D) y≥-5.

You can tell it must be D as greater or less than is dotted while greater equal or less equal would be a solid line.

What are the y-intercept and the asymptote of g(x) = 4x – 6?
Marina CMI [18]

The y-intercept of the line is (0 -6). The given function has no vertical and horizontal asymptotes

<h3>y-intercept and asymptotes of an equation</h3>

A linear equation is an equation that has a leading degree of 1. Given the equation

g(x) = 4x - 6

The y-intercept occurs at a point where x = 0

g(0) = 4(0) - 6

g(0) = -6

Hence the y-intercept of the line is (0 -6)

The given function has no vertical and horizontal asymptotes
