4. D does NOT form a proportion
5. To get the answer you would multiply 45*8=360 then 360/18=20 so n=20

6. same as number 2
multiply 1.2*.6= .72 then .72/1.6= .45 so w=.45

4. (a) 8/14 = 4/7
         20/35 = 4/7
    (b) 6/10 = 3/5
         15/25 = 3/5
    (c) 9/4
         36/16 = 9/4
    (d) 12/15 = 4/5
          30/40 = 3/4
The answer is D.

5. 8/18 = n/45
   18 x n = 45 x 8
   18 x n = 360
    n = 360/18
       = 20
The answer is C.

6. 0.6/1.6 = w/1.2
    0.6 x 1.2 = w x 1.6
    0.72 = w x 1.6
    0.72/1.6 = w
    w = 0.45
The answer is A.

Describe the solution of g(x) shown in the graph.

Ugo [173]

Answer:

All real solutions

Step-by-step explanation:

The given graph is a maximum quadratic function.
The solution to the graph is where the graph intersects the x-axis.
We can see from the graph that, the function intersected the x-axis at two different points, hence its discriminant is greater than zero.
Hence the solution of g(x) are two distinct real solutions.
The solutions are not whole numbers because the x-intercepts are not exact.
The solutions are also not all points that lie on g(x)
The first choice is correct.
