2A) C is correct.
2B) If x + 13 = 28, solve.
If x = 15 and x + 13 = 28, you can solve it two ways:
1. Plug x into 4x + 26 to get a perimeter of 86, or
2. Redo the equation:
3a. Since the 6z is negative, you want an expression the has 5z - (11z). Answers A and D have that in their answer.
But since the 13 is positive, you want the answer that subtracts the smaller number from the larger. Thus, D is your answer since it subtracts 2 from 15.
3b) You think about this question the same way; 6z is positive, so the smaller number is being subtracted from the larger, meaning that 11z - 5z is what you look for. C and D are the two that have that, so now let's look at the second term.
The 13 is negative, so you want the answer that has 2 - 15. The answer that has that is D.
Hope this helps :D

Answer:
Option C is correct
Step-by-step explanation:
The Proportional relationship says that:
then
the equation is of the form :
y = kx .....[1] where k is the constant of Proportionality
As per the statement:
Constant of proportionality (k) =
Substitute in [1] we get;
Therefore, an equation represents a proportional relationship that has a constant of proportionality equal to 1/5 is
A cubic with a positive x³ coefficient will have a generally "/" shape, increasing to the right. When your function is evaluated at x=-2, you get (-2)³-2 = -8-2 = -10. These facts are sufficient to help you select the 3rd choice as being appropriate.
... graph that increases from left to right that passes through ordered pairs negative 2, negative 10; negative 1, negative 3; 0, negative 2; 1, negative 1; and 2, 6
This is a cubic function. The end behavior of the graph will increase to the right and decrease to the left.
