<h2>Answer:</h2>
A one solution because it's x=1
<h3>Step By Step explanation:</h3>
this is the original problem
8x-3=3x+2
we want to have x by itself so. . .
we add three on both sides. it cancels -3. And 2+3=5
8x=3x+5
we subtract 3x on both sides so 8x-3x=5x and 3x cancels on the other side
5x=5
we divide by 5 on both sides to get x by itself
x=1
if it was 1=1 or x=x (the same on both side) it would've been infinite solutions. if the numbers didn't match like 4=6 it would've been no solution
It’s -2 cause it’s on the -2 line
Answer: Simplifying the expression of the substraction of the two complex numbers we get 11-2i
Solution:
(5-5i)-(-6-3i)
Eliminating the parentheses: 5-5i+6+3i
Grouping similar terms: (5+6)+(-5+3)i
Adding the similar terms: 11+(-2)i = 11-2i
I'm sorry! i really wish i could help you out more on this one. personally, i'm pretty confused myself. i think the data should have more years because i'm not sure how you're supposed to give a reasonably close predicted value when it's so far apart. your graph looks really good though other than the trend line should be straight across the points i believe. i could try to link a photo if you're not sure of what i'm talking about. i'll keep looking at this one though and let you know if i figure anything out.
