Answer:
2x +5(y+3)
Step-by-step explanation:
this depends on what you want
x+y+x+y+3(y+5)
expanding this, we have;
2x +2y +3y+15
2x +5y +15
2x +5(y+3)
Answer:
Step-by-step explanation:
y - 9 = 2(x - 1)
y - 9 = 2x - 2
y = 2x + 7
Answer:
Only one extreme value of f(x) is possible.
Step-by-step explanation:
We are given the quadratic function of independent variable x which is f(x) = x² - 7x - 6 ......(1)
Now. the condition for extreme values of f(x) is 
Hence, differentiating both sides of equation (1) with respect to x, we get
= 0
⇒ x = 3.5.
So there is only one value of x for which f(x) has extreme value which is x = 3.5.
Therefore, only one extreme value of the given function is possible. (Answer)
