Equation #1:
Equation #2:
-4 is smaller than 13, so the solution to equation #1 is smaller than the solution to equation #2.
The answer is a.
Answer: Chi-square test
Step-by-step explanation:
A Chi-square test is a test used or applied to check or see if a relationship between two categorical variables. Example
The marketing firm trying to show their client that there is a linear relationship between sales and the amount of money the client has invested in radio advertisements uses chi-square method by comparing the two variables which are Sales made and Amount spent on advert or promotion on radio.
Answer: The solution to the system is (-2, 3)
Step-by-step explanation: In order to graph these equations, plug in any numbers for the value x to solve for the y value. For example, you can choose x to equal -1. Solve for this in both equations: y = -2(-1) - 1 and y = -1 + 5.
Y = -2(-1) - 1
Y = 2 - 1
Y = 1
Y = -1 + 5
Y = 4
Graphing this, you can see the values (-1, 1) for y = -2(-1) - 1 (blue) and (-1, 4) for y = -1 + 5 (red). Continue to solve for y using a variety of x values until you find where both lines cross each other.
