The simplification of each form of expression is;
- (6r + 7) + (13 + 7r) = 13r + 20
- (13 - 3/2r) - (1 - r) = 12 - 1/2r
- (-8 - r) + (2r - 4) = -12 + r
- (7r - 3/2) - (2/3 + 6r) = r - 13/6
<h3>Simplification</h3>
(6r + 7) + (13 + 7r)
= 6r + 7 + 13 + 7r
= 13r + 20
(13 - 3/2r) - (1 - r)
= 13 - 3/2r - 1 + r
= 12 - 3/2r + r
= 12 -3r+2r/ 2
= 12 - 1/2r
(-8 - r) + (2r - 4)
= -8 - r + 2r - 4
= -12 + r
(7r - 3/2) - (2/3 + 6r)
= 7r - 3/2 - 2/3 - 6r
= r -9-4/6
= r - 13/6

Answer:
1/30
Step-by-step explanation:
The zeros of the function are ...
So, the factorization for some leading coefficient 'a' is ...
y = a(x +3)(x -2)²(x -5)
and the y-intercept is ...
y = a(3)(-2)²(-5) = -60a
The graph shows the y-intercept is -2, so we must have ...
-2 = -60a
1/30 = a
The leading coefficient is 1/30.
The answer is c. x+1 (I'm pretty sure)
bearing in mind that an absolute value expression, is in effect a piece-wise expression, so once we remove the bars, we really end up with two siblings, one is negative, the other positive, of the same expression.
The independent variable is the number you put into a function.
The function has no control or influence on it. It's whatever YOU
decided to put in. It's completely independent of the function.
The value that results from what you put in is the dependent variable.
It depends on => what you put in, and => what the function does
with that.
