Answer:

Point A.

Step-by-step explanation:

A complex number is composed of 2 parts: it's Real Part often denoted with Re(z), where z - complex number, Im(z) - imaginary part of z.

The number can be thought of as a point on the xy axis where Re(z) serves as the x coordinate and Im(z) serves as the y component, thus giving you the position. (Re(z), Im(z))

A line passes through the points (0, 4) and (1, 9). What is its equation in slope-intercept
Simora [160]

Answer:

y=5x+4

Step-by-step explanation:

First get slope:

(4-9)/(0-1) = -5/-1 = 5

The y-intercept is where the graph hits the y-axis. That is also the point on the graph where x = 0. We are already given that, with point (0,4).

The y-intercept is 4.

y = mx +b,  m is slope and b is the intercept.

y = 5x +4

Zoe shows her work in finding the solution to 9 – 7x = 7 – 4(2x 3). which choice describes the error in her solution?
FinnZ [79.3K]
I'll assume the above equation is: 9 - 7x = 7 - 4(2x+3)

* do distributive multiplication
9 - 7x = 7 - 8x - 12

*move like terms
-7x + 8x = 7 - 12 - 9

* solve for x
x = 7 - 21
x = -14

To check, substitute x by its value -14

9 - 7x = 7 - 4(2x+3)
9 - 7(-14) = 7 -4[2(-14) + 3]
9 + 98 = 7 - 4(-28 +3)
107  = 7 - 4(-25)
107 = 7 + 100
107 = 107
