Step-by-step explanation:
I wrote it down with steps
I hope you benefit from me
I did the math and it is 4x
Solution
3(-x+(2x+1))=x-1
3(x+1)=x-1
3x+3=x-1 collect like terms
3x-x=-1-3
2x=-4 divide both side by 2
x=-4/2=-2
Step-by-step explanation:
The question above is answered below.
Consecutive numbers are set of numbers that follow one another in ascending or descending order, e.g. 1, 2, 3, 4, 5....
The sum of three consecutive numbers = 72
Let the unknown consecutive numbers be represented by x+1, x+2 and x+3 such that:

Remove the brackets

Collect like terms and simplify


Make 3x subject of formula by subtracting 6 from both sides


To obtain the value of x, divide through by the coefficient of x, which is 3. Hence;


Since x = 22,



The smallest of these numbers is 23.
Check,
23 + 24 + 25 = 72
Answer: The y intercept is 1.
Step-by-step explanation: Sorry I could only answer the one about the y-intercept. So basically finding the y intercept is where the line crosses at the y-axis. So in this case the y-intercept is 1 because thats the point the line crosses at the y-axis. I hope this clarifies your question and I hope this helps. Good Luck on your upcoming test if you have one soon!
