I went to mathamadics.com it gave me all my answers to that type of question
The factor outside the parentheses is -1. Distribute using that factor.
2 - (4 - <em>x</em>) = 7<em>x</em> - 5<em>x</em>
<em />
-1 * 4 = -4 and -1 * -<em>x</em> = <em>x</em>
<em />
2 - 4 + <em>x</em> = 7<em>x</em> - 5<em>x</em>
Simplify.
-2 + <em>x</em> = 2<em>x</em>
<em>x</em> = 2<em>x</em> + 2
-<em>x</em> = 2
<em>x</em> = -2

Answer:</h3>
<em>x</em> = -2
Answer: -185 (choice D)
=========================================================
Explanation:
- x = first integer
- x+1 = second integer
Note how x+1 follows immediately after x. That's what "consecutive" means by definition. An example of consecutive integers would be 7,8,9,10.
Adding those two said integers will lead to -371
first+second = -371
x+(x+1) = -371
2x+1 = -371
2x = -371-1
2x = -372
x = -372/2
x = -186
x+1 = -186+1 = -185
Note how -186+(-185) = -371 to confirm the answer.
The two consecutive integers that add to -371 are -186, -185. The larger of the two is -185 since it's more to the right on the number line.
Hi!
The answer is B. Linear function.
A linear function is when the change in <em>y </em>and <em>x</em><em> </em>is constant. For example, let's make some <em>x</em> and <em>y</em> values.
x 1, 2, 3, 4, 5
y 2, 4, 6, 8, 10
When <em>x</em> increases by 1, <em>y</em> increases by 2. The change in <em>x</em> and <em>y </em>is constant, therefore, that is a linear function.
x 6, 9, 13, 26
y 3, 5, 10, 11
There is no pattern in those numbers, therefore this is not a linear function.
Hope this helps! :)
