Answer:
x = 55 or x = 15
Step-by-step explanation:
Solve Absolute Value.
We know that either 1/5x - 7 = 4 or 1/5x - 7 = -4.
1/5x - 7 = 4
1/5x - 7 + 7 = 4 + 7
1/5x = 11
1/5x (5) = 11 (5)
x = 55 (one possibility)
1/5x - 7 = -4
1/5x - 7 + 7 = -4 + 7
1/5x = 3
1/5x (5) = 3 (5)
x = 15 (second possibility)
Answer:
The scientific notation of 0.91 is: 9.1 × 10-1
Step-by-step explanation:
For the answer to the question above, the power of "y" doesn't influence descending order for x even if it is higher than power of x.
Unordered polynomial is
7x3y3 + 4 - 11x5y2 - 3x2y
Polynomial in descending order looks like this
-11x5y2 + 7x3y3 - 3x2y + 4
Degree of the second term is 5 ( because of x5 )
