Answer: x=4
Step-by-step explanation: You have to distribute the negative signs
x - (4x-7)= 5x-(x+21)
x - 4x + 7 = 5x - x - 21
- 3x + 7 = 4x - 21
28 = 7x
X = 4
For this you need to expand the brackets first:
3(2x+5)-4(2x-7) = 6x+15-8x-28
And then now you need to add and simplify:
6x+15-8x-28 —> 6x-8x= -2x
15-28= -13
So that leaves
-2x - 13
Answer:
<em>B) Victor</em>
Step-by-step explanation:
<em>A positive value for r implies a positive linear correlation, while a negative value for r implies a negative linear correlation. The
</em>
<em>closer |r| is to 1, the stronger the correlation, and the stronger the correlation, the more reasonable the data model. Since |–0.91| =
</em>
<em>0.91, |0.73| = 0.73, |–0.44| = 0.44, and |0.88| = 0.88, the person with the most reasonable model for his or her data is</em><em> B) Victor!</em>
