Samantha conjectures that for x < - 1 it is true that x ^ 5 - 2 > x her conjecture correct? Why or why not?

Incorrect

Step-by-step explanation:

Given

Determine if the conjecture is true

To determine if it's true or not, we have to substitute the values of x in

In the first inequality, we have that

This means that the values of x are: -2. -3, -4......

Substitute -2 for x in

Her conjecture is incorrect because the inequality is not true for x = -2

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
