Answer:
The function f(x)=3x-10 has the greater value at x=8.
Step-by-step explanation:
In the table, x=8 corresponds to y=4.
In the function f(x)=3x-10 when x=8, y corresponds to f(8)=3(8)-10=24-10=14.
SInce 14>4 , the the function f(x)=3x-10 has a greater value at x=8 than the table does.
If we use the formula, which is
, Then it would give us y = 4x - 10! Hope this helped!
Answer:
xy = - 27
Step-by-step explanation:
Note that
(x - y)² = x² - 2xy + y² ← substitute given values, that is
9² = 27 - 2xy
81 = 27 - 2xy ( subtract 27 from both sides )
54 = - 2xy (divide both sides by - 2 )
- 27 = xy
