7y + 10x = 99
y - x = 2
y = 7 , x = 5
Answer:
-4
Step-by-step explanation:
- y = 3(x+5)²-4
- y= 3(x²+10x+25)-4
- y= 3x²+30x+75-4
- y= 3x²+30x+71
Derivate the function
solve the equation y'= 0
- y'= 6x+30
- 6x+30= 0
- 6x= -30
- x = -5
The extrme value of y is reached in -5
y = 3(-5+5)²-4= -4
What are the x values of the table?
Answer:
67/500
Step-by-step explanation:
we have
The decimal number 0.134
