Answer:
(x + 3)² = 14
Step-by-step explanation:
x² + 6x - 5 = 0
Add 5 and 9 on both sides.
x² + 6x + 9 = 14
Factor left side.
(x + 3)² = 14
Take the square root on both sides.
(x + 3) = ±√14
Subtract 3 on both sides.
x = -3 ±√14

Answer:
ΔLMN ~ ΔLFG; scale factor 7/3
Step-by-step explanation:
The ratios of side lengths, shortest to longest are ...
FG : GL : LF = 24 : 36 : 42 = 4 : 6 : 7 (reduced)
MN : NL : LM = 56 : 84 : 98 = 4 : 6 : 7 (reduced)
The side ratios are the same, so ΔLMN ~ ΔLFG. The scale factor is ...
MN/FG = 56/24 = 7/3

Is the system of equations independent inconsistent or dependent?
An independent system of equations has exactly one solution (x,y) . An inconsistent system has no solution, and a dependent system has an infinite number of solutions.What are the 3 types of system of equations?
There are three types of systems of linear equations in two variables, and three types of solutions.
An independent system has exactly one solution pair. The point where the two lines intersect is the only solution.
An inconsistent system has no solution. ...
A dependent system has infinitely many solutions.
Answer:
4. D
5. B
6. B
Step-by-step explanation:
Flowcharts are used to show the steps of a process in a subsequential order. They are not used to represent relations or functions therefore the answer is D
In a function each x value had its own corresponding y value. To be more specific the x value cannot repeat.
In answer choice A the x value 3 and -3 repeats therefore is is not a function
in answer choice b each x value has it's own y value. So this might be the answer but just to be safe let's check the other
In answer choice C the x value 2 repeats multiple times therefore it is not a function
In answer choice D the x value 4 repeats therefore it is not a function
So we can conclude that the answer is B
The dependent variable is the variable the depends on another variable to get it's value. in the description of the question it says that the number of products on his plastic bag lists INFLUENCES how many plastic bags he brings to the store.This means that the number of plastic bags depends on the number of products on the plastic bags lists. Hence the answer is B
