Answer:
Step-by-step explanation:
x² + 6x + 1 = 0
a = 1 , b = 6 , c = 1
33 * 3 + 3/3 = 100
I do not believe u have to use all of the operations because it says " at most once ".
Answer:
x = -8
Step-by-step explanation:
x = 2y - 4 --- Equation 1
7x + 5y = -66 --- Equation 2
I will be using the substitution method to solve this.
Substitute x = 2y - 4 into Equation 2:
7x + 5y = -66
7(2y - 4) + 5y = -66
Evaluate.
14y - 28 + 5y = -66
Evaluate like terms.
19y - 28 = -66
Isolate 19y.
19y = -66 + 28
= -38
Find y.
y = -38 ÷ 19
y = -2 --- Equation 3
Substitute y = -2 into Equation 1:
x = 2y - 4
x = 2(-2) - 4
Evaluate.
x = -4 - 4
x = -8
I would assume Independent because pulling 1 marble doesn't cause you to pull a second one.

Constant in a mathematical expression is a term whose value never changes.
The terms with x and y will vary based on the variable x and or y.
