First, find the gradient/slope:
Use slope formula:
m=(y2-y1)/(x2-x1)
=(11-5)/(3-1)
=6/2
=3
Then use the line equation formula:
y=mx+c
You can substitute (1,5) if you like, also must substitute the slope as well!
5=3x1+c
c=2
Then find the full equation, which gives you the answer:
y=3x+2

Answer:
always true
Step-by-step explanation:
Given
2(x + 3) = 5x + 6 - 3x ← distribute left side
2x + 6 = 2x + 6
Since both sides are equal then any real value of x is a solution.
Thus the equation is always true
Answer:
≈ 542,029 copies
Step-by-step explanation:
37,400 copies represents a 6.9% of the total copies sold to date.
Therefore; Copies sold to date will be 100%
Thus;
Total number of copies sold = (37,400/6.9)× 100
= 542,028.99 copies
<u>≈ 542029 copies</u>
