6x + 7(1-x) = -4(x-4)
6x + 7 - 7x = -4x + 16
-x + 7 = -4x + 16
-x + 4x = 16 - 7
3x = 9
x =9/3
x = 3

Let f(x)=√3x and g(x)=x-6 What's the smallest number that is in the domain of fog?
yaroslaw [1]

9514 1404 393

Answer:

  6

Step-by-step explanation:

Maybe you have ...

  f(x) = √(3x)

  g(x) = x-6

Then ...

  f(g(x)) = √(3(x -6))

The square root function is only defined for non-negative arguments, so we require ...

  3(x -6) ≥ 0

  x -6 ≥ 0 . . . . . divide by 3

  x ≥ 6 . . . . . . . . add 6

The smallest number in the domain of f(g(x)) is x = 6.

Need points ?Answer question simple.
Tresset [83]

Answer:

45 degrees

Step-by-step explanation:

A straight line is an angle with a measure of 180°, but becasue it looks like we have two angles that create the 180° angle, therefore, it is a supplementary angle.

Knowing this

2X = 90° (right angle)

so (2X) + (2X) = 180° (supplementary angle)

Therefore, to find X you can do

2X = 90

divide by 2 on both sides (to isolate the variable we are trying to find which is X)

and you get....

X= 45 becasue 2 times 45 equals 90

answer: X=45°
