6 0

Answer:

6

Step-by-step explanation:

To solve, first plug in 4 as your x value for your g(x) equation.

g(4)=\sqrt{4-3} \\g(4)=\sqrt{1} \\g(4)=1

Next, plug in the value of g(4) into your f(x) equation for x.

f(1)=-1+7\\f(1)=6

Line segment ab has endpoints a(9, 3) and b(2, 6). find the coordinates of the point that divides the line segment directed from
Dominik [7]
When we are to divide the line segment such that the ratio is 1:2, there are actually 3 parts of the segment. First, we determine the distance between the coordinates and divide the distance by 3. Then, we add the quotient to the x-coordinate.

x-coordinate:    (2 - 9) / 3 = -7/3
y-coordinate:    (6 - 3 ) / 3 = 1

Adding them to the coordinates of a,
           x - coordinate: (9 - 7/3) = 20/3
           y - coordinate: (3 + 1) = 4
Thus, the coordinates are (20/3, 4).
