Let x be number of black markers
4.5x + 2x3.25x + 3x1.98x = 284.24
16.94x = 284.24
x = 16.78 = 17
The person bought 17 black pens, 34 red and 51 green
Using the absolute value function, all the points that are a distance CD away from point A are given by:
|x - A| = CD
<h3>What is the absolute value function?</h3>
The absolute value function is given by:
It measures the distance of a point x to the origin, which is given to x = 0.
All the points that are a distance CD away from point A are given by:
|x - A| = CD
This means that the solutions are:
- X - A = -CD, which means that x is CD units to the left of A.
- X - A = CD, which means that x is CD units to the right of A.

Y=x^2+12x+30
8x-y=10
sub x^2+12x+30 for y in the secodn equaiton
8x-(x^2+12x+30)=10
8x-x^2-12x-30=10
-x^2-4x-30=10
times -1
x^2+4x+30=-10
add 10 both sides
x^2+4x+40=0
use quadratic formula
we find that we have 2 imaginary roots and therefor are not on the real plane, they are not plotted on the imaginary plane
no real solution
x=-2+6i or -2-6i
the interseciton on the imaginary plane is
(-2+6i, -26+48i) or (-2-6i,-26-48i)
Answer:

Step-by-step explanation:
2 is no
