Answer:
Step-by-step explanation:
8 / x = -4
the solution of a number divided by 8 is negative four.....this is wrong
this is saying : x / 8 = -4
Since both sides has same factor (x+6), we can set (x+6) equal to 0.
So we would have one of solution x = -6. (because this would have us x·0 = 4·0 )
Now when x is NOT equal to -6, we can divide both sides by (x+6), leaving us
x = 4
So answer is x = -6 or 4.
Answer: 29.3
Step-by-step explanation:
Abby's average after taking 31 quizzes is 76.
Total test scores= 31 × 76 = 2356
After Abby's teacher drops her 3 lowest test scores, her average increases to 81. This means that (31-3)= 28 test scores were used.
Total scores = 28 × 81 = 2268
Sum of Abby's three lowest score
= 2356 - 2268
= 88
Average of the three scores will now be 88 divided by 3
= 88/3
= 29.3
The average is 29.3
Answer:
The answer to your question is:
Step-by-step explanation:
Data
Focus = (3, 3)
Vertex = (1, 3 )
Horizontal parabola that opens to the right
Process
p = 2 distance to the vertex to the focus
Formula
(y - k)² = 4p (x - h)
( y - 3)² = 4(2)(x - 1)
y² - 6y + 9 = 8x - 8
y² - 8x - 6y + 17 = 0
