Answer:
y = -6
Step-by-step explanation:
Step 1: Define
8x - 9y = -50
x = -13
Step 2: Substitute and solve for <em>y</em>
8(-13) - 9y = -50
-104 - 9y = -50
-9y = 54
y = -6
Answer:
Median
Step-by-step explanation:
Since the data has an outlier (12,985), mean is not the best average.
This data set does not have a modal value
Therefore the best option is Median

Answer:
Step-by-step explanation:
<span>|7x-7|+3 = 4x+1 ⇒⇒⇒ add (-3) to both sides
</span>
<span>∴ |7x-7| = 4x - 2
</span>
According to the absolute rule
∴ 7x - 7 = 4x - 2 OR -(7x - 7) = 4x - 2
7x - 4x = 7 - 2 l 7x - 7 = -4x + 2
3x = 5 l 7x + 4x = 2 + 7
x = 5/3 l 11 x = 9 ⇒⇒⇒ x = 9/11
∴ x = 5/3 and 9/11
So, the correct answer is option <span>B. 5/3 and 9/11</span>
