Your answer is -2,146 because you have to try to get x by itself. So to do that you must subtract 2,318 and 18 from 190 to get your answer.

Answer:
Step-by-step explanation:
Given the equation of a line expressed as y = 3x-1, we are to find y = f(x) for the following values of x in the table.
If y = 3x-1, then f(x) = 3
When x = -1
f(-1) = 3(-1)-1
f(-1) = -3-1
f(-1) = -4
<em>Hence when x = -1, f(x) = -4</em>
<em></em>
When x = 0
f(0) = 3(0)-1
f(0) = 0-1
f(0) = -1
<em>Hence when x = 0, f(x) = -1</em>
<em></em>
When x = 2
f(2) = 3(2)-1
f(2) = 6-1
f(2) = 5
<em>Hence when x = 2, f(x) = 5</em>
Answer:5 and 3
So we let the number take the letter b, anc the expression of the question is:
b^2+15=8×b.....so
b^2+15=8b
Then we take the 8b to the other side of the equal sign so that it becomes...
b^2+15-8b=0
Hence it becomes a quadatic equation following the principle ax^2+bx+c where x is the unknown...
From there we work out to get two different numbers...either b-5=0
b=5
Or b-3=0
b=3
So the two numbers are 5 and 3
Hopefully this is right! x
