Answer:
y = -2 x = 0
Step-by-step explanation:
1. 3x-4y = 8
2. 18-5y = 10
Multiply equation 1 by 6
3. 18x-24y = 48
Subtract equation 2 from equation 3
4. -19y = 38
y = 38/-19
y = -2
Sub y = -2 back into equation 1
3x-4(-2) = 8
3x + 8 = 8
3x = 0
x = 0/3
x = 0
Answer:
A. Matrix A
Step-by-step explanation:
When you put a systems of linear equations in matrix form, you take only the coefficients of the <em>xy </em>terms and sort them. <em>x</em> goes first, <em>y</em> comes after, and the numbers after the bars are the constants.

Answer:
The actress has the more extreme age because
Step-by-step explanation:
Given
Male Athletes:
Female Athletes
Required
Determine which athlete had more extreme age
To do this, we simply calculate the standard z score using
For the actor:
For the actress:
Comparing both z values;
The actress has the more extreme age because
- <em>It has a positive z value</em>
- <em>Its z value is greater than that of the actor</em>
<em></em>
