Answer:no solution the lines are parallel they have the same slope
Step-by-step explanation:
8x+2y=14
-8x. -8x
2y= -8x+14
Divide all by 2
Y= -4x +7
8x+2y=4
-8x. -8x
2y= -8x+4
Divide by 2
Y-= -4x+2
Since they both have -4x they have the same slope they never touch making them parallel
For this case we have the following expression:
We must find the value of the expression when:
Substituting the values in the expression we have:
Thus, the value of the expression is 2.
Answer:
The value of the expression is 2
Option A
the derivitive is just the slope
minimum happens when the derivitive goes from negative to positive, imagine a slope of the function, the minimum is where the slope goes from neative to positive, and to get there, it has to pass through 0
max happens when the derivitive goes from positive to negative
increaseing is when the derivitive is positive
so, based on what you said, the slope of f(x) is 0 at x=-3, x=1 and x=2 since those are where the derivitive is 0 (derivitive is just the slope)
A and B are wrong because the derivitive isn't 0 at those points
C is correct because increasing means that the derivitive is positive, and so therefo since the only hoirontal place in between 1 and 2 is 1.5, it must remain positive throughout and not dip down, C is right
D is wrong then
answer is C
Answer:
Step-by-step explanation:
(2x+4)° + 42° = 180°
x = 67°
