Answer:
x = 1
Step-by-step explanation:
-5x-(-7-4x)-2(3x-4)
-5x + 7 - 4x - 6x + 8 First step is to factor all the numbers out so you have no parenthesis. In this case -(-7 just turns into + 7 because two negatives equal a positive. As well as -2*3x and -2*-4 which gives you -6x + 8.
-15x + 15 In this step you combine like terms.
-15x = -15 Next you move the whole number to the other side of the equation by subtracting it from both sides.
x = 1 Finally you divide -15 by -15 to get x by its self.
Answer:
x=5
Step-by-step explanation:
Set the 2 equations equal to each other and solve for x.
11x-28=7x-8
add 28 to both sides (-8+28=20)
11x=7x+20
subtract 7x from both sides (11x-7x=4x)
4x=20
divide both sides by 4 to isolate x (20/4=5)
x=5
Answer:
D.
Step-by-step explanation:
The point must be a critical point but it could be a saddle point. If the point is a saddle point it would not be neither a maximum nor a minimum. So it must be critical but it does not follow directly that it has a local maximum or local minimum.
Therefore D. (a,b) would be a candidate, but is not necessarily a maximum or minimum. It could be a saddle.
